History of the Illegal Dumping of FRP Wrecked Vessels - From 1994 to the 2020s In 1994, the problem of illegally dumped FRP (fiberglass-reinforced plastic) wrecked vessels became severe along coastlines and in ports nationwide. A nationwide survey found that 40% of the 1,573 confirmed wrecked vessels were FRP boats. Due to their high durability, they did not biodegrade, raising concerns about long-term environmental impacts. Particularly, fishing industry stakeholders and marine environmental protection groups pointed out the deterioration of scenery and the impact on fishing grounds. In response to this situation, the Japan Coast Guard announced a policy in 1996 to strengthen enforcement against the illegal dumping of FRP vessels, introducing measures such as affixing warning stickers, providing guidance on proper disposal, and applying penalties.
Entering the 2000s, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Ministry of the Environment (MOE) promoted measures for the proper disposal of FRP vessels, advancing the development of recycling technologies. In November 2005, the Japan Marine Industries Association (JBIA) commenced operation of the "FRP Vessel Recycling System," facilitating the processing of FRP waste vessels, including their conversion into cement raw materials. However, illegal dumping remained a significant problem due to high disposal costs. According to a 2003 report by the Ministry of the Environment, approximately 78% of the 884 newly confirmed illegally dumped vessels were FRP boats, and 93% of the pleasure boats involved were made of FRP.
By the 2020s, the FRP boat recycling system was operating continuously, with regular collection points established in each region. Recycling technology using cement kilns became the standard method for proper FRP boat disposal and received official government recognition. Furthermore, information on FRP boat disposal methods became more widely available, enabling owners to arrange proper disposal through "registered dealers" within the FRP Boat Recycling System.

FRP廃船の不法投棄問題の歴史 - 1994年から2020年代まで
FRP廃船の不法投棄問題の歴史 - 1994年から2020年代まで
1994年、全国の海岸や港湾でFRP（繊維強化プラスチック）製の廃船が不法投棄される問題が深刻化した。全国調査では、確認された1573隻の廃船のうち40％がFRP船であり、耐久性の高さから自然分解されず、長期的な環境影響が懸念された。特に、漁業関係者や海洋環境保護団体から、景観の悪化や漁場への影響が指摘された。この状況を受け、海上保安庁は1996年からFRP廃船の不法投棄取り締まりを強化する方針を発表し、警告シールの貼付や適正処理の指導、罰則の適用を導入した。
2000年代に入ると、国土交通省や環境省はFRP船の適正処理に関する対策を推進し、リサイクル技術の開発が進められた。2005年11月には一般社団法人日本マリン事業協会（JBIA）が「FRP船リサイクルシステム」の運用を開始し、FRP廃船のセメント原料化などの処理が進められた。しかし、処理費用の高さから不法投棄は依然として問題視され、環境省の2003年の報告では、新たに確認された不法投棄廃船884隻のうち約78％がFRP船であり、プレジャーボートでは93％がFRP製であった。
2020年代に入ると、FRP船のリサイクルシステムは継続的に運用され、地域ごとに定期的な回収受付が行われるようになった。FRP船の適正処理として、セメント焼成によるリサイクル技術が標準的に活用され、国から正式に認められた。また、FRP船の廃棄方法に関する情報提供が進み、所有者はFRP船リサイクルシステムの「登録販売店」を通じて適正な廃棄処理ができるようになった。

History and Current Status of Tachikawa Town's Citizen Energy Conservation Project in the 2020s - 2003 to 2023 Yamagata Prefecture's Tachikawa Town launched its "Citizen Energy Conservation Project" in 2003 to promote energy savings across the entire community. Initially involving 100 households, the project aimed to reduce annual electricity consumption by approximately 500,000 kWh. With cooperation from local businesses like the "Shonai Electric Power Cooperative" and "Tatekawa Energy Co., Ltd.," energy-saving targets were set for each household. A system was introduced where participants who met their targets received "Fuchan Tickets," usable at local shops. Within six months of the project's start, the total electricity consumption of participating households was reduced by approximately 50,000 kWh, and CO₂ emissions decreased by about 20 tons annually. Thus, this resident-participation energy-saving initiative steadily progressed, successfully combining heightened loca
l environmental awareness with economic revitalization. Entering the 2020s, the Power Saving Station Project expanded further, reaching 300 participating households by 2023. Annual total electricity consumption was reduced by approximately 20% from the initial 500,000 kWh, now maintained at around 400,000 kWh. Yamagata Clean Energy Co., Ltd. joined as a new partner company, aiming to further improve energy efficiency and enhance the supply system. According to the latest data, an average annual reduction of 1,200 kWh per household has been achieved, along with a decrease in CO₂ emissions of approximately 50 tons per year. Furthermore, the scope of use for "Fuchan Tickets" has been expanded, making them usable not only at local shops but also at eco-shops and recycling stores. Through collaboration with the "Tachikawa Town Recycling Center," residents can now purchase recycled appliances at a discount, strengthening resource circulation within the town. Furthermore, solar p
ower generation systems have been installed at public facilities, reducing annual electricity consumption at the town hall and public schools by 15%. As a result, the town as a whole has achieved an annual electricity reduction of approximately 1 million kWh and a reduction of over 200 tons of CO₂ emissions per year.
Moving forward, Tachikawa Town plans to further introduce and optimize energy-saving equipment, aiming for participation from all households by 2025. This project also revitalizes the local economy through the use of "Fuchan Tickets," which function similarly to local currency. Tachikawa Town envisions expanding this sustainable regional model to Kyushu and other areas. The Power Saving Station Project is anticipated to develop further as a successful example of enhancing resident participation and regional energy management.

ower generation systems have been installed at public facilities, reducing annual electricity consumption at the town hall and public schools by 15%. As a result, the town as a whole has achieved an annual electricity reduction of approximately 1 million kWh and a reduction of over 200 tons of CO₂ emissions per year.
Moving forward, Tachikawa Town plans to further introduce and optimize energy-saving equipment, aiming for participation from all households by 2025. This project also revitalizes the local economy through the use of "Fuchan Tickets," which function similarly to local currency. Tachikawa Town envisions expanding this sustainable regional model to Kyushu and other areas. The Power Saving Station Project is anticipated to develop further as a successful example of enhancing resident participation and regional energy management.
立川町の町民節電所プロジェクトの歴史と2020年代の現状 - 2003年から2023年
立川町の町民節電所プロジェクトの歴史と2020年代の現状 - 2003年から2023年
山形県立川町の「町民節電所プロジェクト」は、2003年に地域全体で省エネを促進するために開始されました。当初は100世帯が参加し、年間約50万kWhの電力消費を抑制することを目標としていました。地元企業の「庄内電力協同組合」や「立川エネルギー株式会社」の協力のもと、各家庭に省エネ目標が設定され、達成者には地元商店で利用できる「フーチャンチケット」が贈呈される仕組みが導入されました。プロジェクト開始から半年で、参加世帯の総消費電力は約5万kWh削減され、CO₂排出量も年間で約20トン減少しました。このように、住民参加型の省エネ活動として、地域の環境意識と経済活性化を両立させる取り組みが着実に進行しました。
2020年代に入ると、節電所プロジェクトはさらに拡大し、2023年には参加世帯数が300に達しました。年間総消費電力も当初の50万kWhから約20%削減され、現在では40万kWhに抑えられています。新たに「山形クリーンエナジー株式会社」が協力企業として参画し、エネルギー効率のさらなる向上と供給体制の整備が図られました。最新のデータによれば、一世帯あたり年間平均1200kWhの削減が実現し、CO₂排出量も年間約50トン減少しています。
また、「フーチャンチケット」の使用範囲も拡充され、地元商店に加えて、エコショップやリサイクル店舗などでも利用可能となりました。「立川町リサイクルセンター」との連携により、家電リサイクル品の割引購入もできるようになり、町内での資源循環が強化されています。さらに、町内の公共施設には太陽光発電システムが導入され、町役場や公立学校の年間電力使用量も15%削減されました。この結果、町全体で年間約100万kWhの電力削減と、年間200トン以上のCO₂排出削減が達成されています。
今後、立川町は2025年までに全世帯参加を目指し、省エネ機器のさらなる導入と効率化を進める計画です。このプロジェクトは、地域通貨のように利用される「フーチャンチケット」による地域経済の活性化も果たしており、立川町は持続可能な地域モデルとして九州や他地域にも展開する構想を抱いています。節電所プロジェクトは、住民の参加意識と地域のエネルギー管理を高める成功例として今後の発展が期待されています。

### History of the PCB Waste Disposal Project in the Hibikinada District of Kitakyushu City **Project Initiation (2001–2004)** In November 2001, the Environmental Services Agency (now the Environmental Restoration and Conservation Agency) planned a PCB (polychlorinated biphenyl) waste disposal project in the Hibikinada district of Kitakyushu City and received approval from the Ministry of the Environment. PCBs are hazardous substances used in transformers and capacitors, posing long-term environmental contamination risks. This project employed pretreatment technologies combining solvent washing and vacuum thermal decomposition, along with dechlorination decomposition technology for liquid treatment. The facility began operations in 2004, with a plan to complete processing within 12 years.
**Initial Results (2004–2010)** The facility commenced operations as planned, processing PCB waste transported from Kyushu and Kansai. During this period, the Kyushu facility was recognized as a model case meeting safety standards and became a national hub for PCB treatment.
**Extension of Processing Deadline (2010–2024)** Originally scheduled for completion by the end of fiscal year 2014, the processing deadline was extended twice to accommodate newly discovered PCB waste and additional waste identified through excavation surveys. By the end of March 2019, approximately 62,000 transformers and capacitors—the first planned processing targets nationwide—were completed. In 2021, responding to a national request, Kitakyushu City decided to continue the processing operations. **Operations Termination and Demolition (2024 Onward)**
On March 31, 2024, the JESCO Kitakyushu Plant ceased operations. The total volume of PCB waste processed reached approximately 10,000 tons, earning recognition as a successful PCB waste treatment case both domestically and internationally. Since then, facility dismantling and removal work has been underway, with completion scheduled for around fiscal year 2029. Following removal, soil contamination surveys and safety confirmation are planned.
**Treatment of Low-Concentration PCB Waste (Ongoing)** Treatment of low-concentration PCB waste is being handled by 31 certified contractors nationwide, with processing also underway in Tobata Ward, Kitakyushu City. This treatment is scheduled for completion by the end of fiscal year 2026. However, the volume of untreated items, such as transformers contaminated during manufacturing, remains substantial. Continued awareness and effort are necessary to achieve full completion.
**Contribution to Environmental Conservation** For over 20 years, the PCB treatment project in the Hibikinada area of Kitakyushu City has played a vital role in environmental conservation within Japan. This project has not only achieved safe and reliable waste disposal through collaboration with local residents and businesses but also contributed to reducing future environmental risks.

### 北九州市響灘地区におけるPCB廃棄物処理事業の歴史
### 北九州市響灘地区におけるPCB廃棄物処理事業の歴史
**事業の開始（2001年～2004年）**
2001年11月、北九州市響灘地区において、環境事業団（現・環境再生保全機構）がPCB（ポリ塩化ビフェニル）廃棄物の処理事業を計画し、環境省から認可を受けました。PCBは変圧器やコンデンサーに使用されていた有害物質で、長期的な環境汚染リスクが指摘されていました。この事業では、溶剤洗浄や真空加熱分解を組み合わせた前処理技術や、液処理での脱塩素化分解技術が採用されました。施設は2004年に稼働を開始し、処理完了までに12年を要する計画でした。
**初期の成果（2004年～2010年）**
施設は計画通り稼働を開始し、九州や関西から搬入されたPCB廃棄物の処理が進められました。この期間中、響灘地区の施設は安全基準を満たしたモデルケースとして評価され、全国的なPCB処理の拠点となりました。
**処理期限延長（2010年～2024年）**
当初の予定では2014年度末までに処理を完了する計画でしたが、新たに発見されたPCB廃棄物や掘り起こし調査による追加廃棄物に対応するため、処理期限が2度延長されました。2019年3月末には、全国で初めて計画的処理対象である変圧器・コンデンサー約62000台を完了。2021年には、国からの要請を受け、北九州市は処理事業の継続を決定しました。
**操業終了と解体（2024年以降）**
2024年3月31日、JESCO北九州事業所は操業を終了しました。処理されたPCB廃棄物の総量は約10000トンに上り、国内外でPCB廃棄物処理の成功事例として評価されました。その後、施設の解体撤去作業が進行中であり、2029年度頃の完了を予定しています。撤去後は、土壌汚染調査と安全性の確認が行われる予定です。
**低濃度PCB廃棄物の処理（現在進行中）**
低濃度PCB廃棄物の処理については、全国31か所の認定業者が対応しており、北九州市戸畑区でも処理が進められています。この処理は2026年度末までに完了する予定ですが、製造過程で汚染された変圧器などの未処理量が膨大であり、処理完了には引き続き周知と努力が必要とされています。
**環境保全への寄与**
20年以上にわたり、北九州市響灘地区のPCB処理事業は、日本国内の環境保全に重要な役割を果たしました。この事業は、地域住民や事業者との連携を通じ、安全で確実な廃棄物処理を実現しただけでなく、将来的な環境リスクの軽減にも寄与しています。

Proper Disposal of Medical Waste and Its Challenges: February 2003 Amid frequent outbreaks of nosocomial infections and infection incidents among waste disposal workers, highly infectious medical waste was designated as "infectious waste" under the Specially Controlled Waste category in July 1992. This designation covered items such as blood-soaked gauze, syringe needles, and scalpels, while less infectious waste remained classified as regular medical waste. Concurrently, new licensing requirements for disposal companies and mandatory use of waste manifests were implemented. According to a 1998 Ministry of Health survey, infectious waste discharged from medical institutions reached 150,000 tons, with approximately 6,000 licensed collection/transport companies and 400 licensed treatment facilities. However, improper treatment and illegal dumping of infectious waste persisted. As recently as summer 2002, Japan's largest illegal dumping incident was uncovered near the border of
Aomori and Iwate Prefectures. The illegally dumped industrial waste totaled approximately 820,000 cubic meters, significantly exceeding the volume in the Toshima Incident in Kagawa Prefecture (500,000 cubic meters). Tracing the waste back to its sources using manifests revealed that among the 2,600 waste-generating entities, medical institutions accounted for the largest share at 355. Most were operators in the Tokyo metropolitan area, with national and university hospitals featuring prominently on the list.
Proper disposal of 1 kg of infectious waste via incineration is said to cost at least ¥100 for incineration fees and ¥150-200 for transportation costs, including specialized sealed containers. However, since infectious waste was designated as such in 1992, new processors entered the market in succession, intensifying competition and leading to a price dumping war among operators. Until recent years, prices of 50 to 60 yen per kg—only slightly higher than the standard industrial waste disposal cost of 20 yen per kg—were rampant. This price is simply not feasible for proper disposal.
Movement Toward Proper Treatment Intensifies Due to this failure to bear proper treatment costs, the infectious waste treatment market has not developed healthily. However, the situation is changing. Starting in 1996, the National Industrial Waste Federation launched the "Proper Treatment Program," where processors self-check based on a proper treatment checklist and publish the results. Furthermore, coinciding with the strengthened producer responsibility under the revised Waste Management and Public Cleansing Act, the Tokyo Medical Association established a "Medical Waste Consultation Desk" and started educational workshops for special management industrial waste managers at medical institutions. Additionally, the Japan Medical Association Research Institute (http://www.jmari.med.or.jp/) began offering the "Japan Medical Association Research Institute Certified Infectious Waste Safe Disposal Promotion Specialist Training Course" starting in March 2003.
Furthermore, since 1996, the Japan Industrial Waste Treatment Promotion Center has operated a certification system for collection and transport containers used in infectious waste disposal, ensuring they are suitable for proper treatment. As of December 2002, the following containers are registered: plastic containers from Tensho Electric Industry (Mippel), Idemitsu Plastics (Medipell), Asahi Pritec (Disposal BOX), Gifu Plastics (Respell), and Kodama Resin Industry (Medical Box); paper containers from Kusaka Industry (Mercon Clean) and Niigata Paper Container Industry (Cerapcapsule). While the cost of a 20-liter plastic container is approximately ¥3,000, which is somewhat high, preventing widespread adoption, these containers are essential consumables for proper disposal. Consequently, their adoption is gradually increasing across companies. The Fuji System Pack Group has launched the "Mippear Association," holding study sessions for information exchange primarily with 50 re
lated processing companies nationwide. Meanwhile, the Idemitsu Group is accelerating adoption efforts, such as publishing the medical waste information magazine "Medimaru."
New Processing Technologies Replacing Incineration If processing costs stabilize at appropriate levels, the market is projected to reach approximately 45 billion yen in processing fees alone. This opens business prospects not only for intermediate processing operations but also for processing equipment, transport/collection containers, and related sectors. With an aging population, waste generation is increasing from elderly health facilities, nursing homes, home healthcare, and general households, suggesting further market expansion.
In the intermediate treatment sector, Aso Mine (Fukuoka Prefecture) began trial operations in January 2002 at the Kitakyushu Eco-Town with its medical waste recycling plant, "Econovate Hibiki." The 8,500-square-meter site houses a crusher, high-frequency heating sterilizer, sorting machine, solid fuel production machine, and molding machine, with a processing capacity of 24 tons per day. It collects over 5,000 tons of medical waste annually from contracted medical institutions. After crushing and sterilizing the waste, it is sorted by material type. Plastics suitable for material recycling are reground into collection containers within the plant for reuse at the contracting hospitals. Other materials are converted into solid fuel at the plant for use in Aso Group cement factories. Iron and glass components are also utilized as cement raw materials. Meanwhile, the processing equipment is not only used by processors advancing proper treatment but also by...

医療廃棄物の適正処理と課題：2003年2月
医療廃棄物の適正処理と課題：2003年2月
院内感染や処理業者の感染事故が多発する中、1992年7月に医療廃棄物の中でも感染性の高いものが「感染性廃棄物」として特別管理廃棄物に指定された。対象は血液付着のガーゼ、注射針、メスなどで、感染性の低いものは通常の医療廃棄物とされた。同時に処理業者の新規許可申請やマニフェストの義務付けも行われた。98年度の厚生省調査によると、医療機関からの感染性廃棄物排出量は15万トンに達し、収集運搬許可業者は約6000社、処理業者は400社に上る。
だが、これまで、感染性廃棄物の不適正な処理や不法投棄は絶えなかった。最近でも、02年夏に青森・岩手県境で国内最大規模の不法投棄事件が発覚した。不法投棄された産廃は、香川県・豊島事件（50万立方メートル）を大幅に上回る約82万立方メートル。マニフェストをもとに排出業者を洗い出したところ、2600の排出業者のうち、医療機関が355と最も多かった。ほとんどが首都圏の事業者で、国公立・大学病院が軒並み名を連ねているという。
感染性廃棄物1 kgの適正処理には焼却の場合、最低でも焼却費用に100円、専用の密閉容器を含めた運搬費用に150~200円がかかるといわれる。しかし92年の感染性廃棄物指定以降、処理業者の新規参入が相次ぎ競争が激化し、業者間でダンピング合戦が行なわれた。近年まで、通常の産業廃棄物処理費用20円／kgに若干色をつけた50~60円/kgという価格が横行していた。とても適正処理できるとは考えられない価格だ。
適正処理に向けた動きが活発化
こうした適正な処理費用が負担されない状況から、これまで、感染性廃棄物処理関連市場も健全に育成されてこなかった。しかし状況は変わりつつある。全国産業廃棄物連合会は96年から、処理業者が適正処理チェックリストに基づき自己チェックし、その結果を公表していく「適正処理プログラム」を開始した。また、廃棄物処理法改正で排出者責任が強化されたのにあわせ、東京都医師会では「医療廃棄物相談窓口」を設置し、医療機関の特別管理産業廃棄物管理責任者向けの教育・研修会をスタートさせたほか、日医総研（http://www.jmari.med.or.jp/）でも「日医総研認定・感染性廃棄物安全処理推進者養成講座」を03年3月から開始する。
また日本産業廃棄物処理振興センターでは96年から感染性廃棄物処理に使われる収集・運搬容器に関して、正しい処理ができる容器であることを認定する制度を始めている。02年12月現在、プラ容器として天昇電気工業（ミッペール）、出光プラスチック（メディペール）、アサヒプリテック（ディスポーザルBOX）、岐阜プラスチック（リスペール）、コダマ樹脂工業（メディカルボックス）、紙容器として日下工業（メルコンクリーン）、新潟紙器工業（セラカプセル）の容器が登録されている。プラ製20リットル容器で約3000円と若干高額なため、まだ本格普及には至っていないが、適正処理には欠かせない消耗品であり、各社とも徐々に導入が増えているという。富士システムパックグループでは「ミッペール会」を発足し、全国の
関係処理業者50社を中心に情報交換を兼ねた勉強会を開催しているほか、出光グループでは医療廃棄物情報誌「メディまる」を発刊するなど普及に向けた動きを加速している。
焼却に代わる新たな処理技術
適正な処理価格に落ち着けば、処理費用だけで450億円程度が見込まれる。それに伴い中間処理事業のほか、処理装置や運搬・回収容器などでも事業展望が開けてくる。高齢化が進んでいることで老人保健施設や老人ホーム、在宅医療など一般家庭からの排出も増加しており、市場規模はさらに拡大が予想される。
中間処理事業では、麻生鉱山（福岡県）が02年1月から北九州市エコタウンで、医療廃棄物再生工場「エコノベイト響」による試験操業を開始している。敷地面積8500平方メートルに破砕機・高周波加熱滅菌装置、選別機、固形燃料製造機、成型機などを備え、処理能力は1日当たり24トン。契約した医療機関から年間5000トンを超える医療廃棄物を回収し、破砕・滅菌した後、素材ごとに選別する。マテリアルリサイクルできるプラスチックは工場内で収集容器に再生し、契約先の病院で利用する。その他の素材は工場内で固形燃料にして麻生グループのセメント工場で利用。鉄やガラス分も、セメント原料として利用している。
一方、処理装置は、適正処理を進める処理業者だけでなく、処理

The Darkness of Waste and the Light of Purification: The Path to Recovery from Illegal Industrial Waste Dumping Shadows of illegal dumping pile up on barren land. The scars on the environment, spreading silently yet surely, would eventually be exposed to society's gaze. On January 20, 2003, the Ministry of the Environment established an investigation team, gathering experts including former police officers, lawyers, and surveyors, to dispel this darkness.
The Darkness of Waste and the Light of Purification: The Path to Recovery from Illegal Industrial Waste Dumping Shadows of illegal dumping pile up on barren land. The scars on the environment, spreading silently yet surely, would eventually be exposed to society's gaze. On January 20, 2003, the Ministry of the Environment established an investigation team, gathering experts including former police officers, lawyers, and surveyors, to dispel this darkness.
An estimated 670 illegal dumping sites scattered nationwide. Restoring them to their original state was calculated to require a staggering 90 billion yen. Who should bear the responsibility? Who polluted the environment, and who would restore its purity? Efforts progressed to identify those involved and calculate their liability costs, while measures to reduce the burden on local governments were also explored.
Then, a new sword was forged to confront the darkness. On February 20, 2003, the "Act on Special Measures Concerning the Removal of Obstructions Caused by Specified Industrial Waste," commonly known as the "Industrial Waste Special Measures Act," was approved by the Cabinet. This law promoted the restoration of sites illegally dumped during the concentrated period of the past decade and strictly pursued the responsibility of waste generators and transporters.
Furthermore, as another framework for regenerating contaminated land, the Soil Contamination Countermeasures Act came into effect in February 2003. It mandated decontamination measures for landowners of sites confirmed to be contaminated with hazardous substances. Prefectural governors were granted the authority to order decontamination when there was a risk of health hazards.
Furthermore, as a new mechanism to curb waste disposal, Nara Prefecture considered introducing an "Industrial Waste Tax (tentative name)" on January 6, 2003. This initiative proposed levying a tax of 1,000 yen per ton of waste delivered to final disposal sites, with the revenue earmarked for funding measures to suppress illegal dumping and environmental conservation.
Thus, to shed light on the dark world of illegal dumping, the government began moving forward with legal reforms and environmental countermeasures. However, problems surrounding waste disposal remain endless. To eradicate the root of environmental crimes, not only must systems be strengthened, but a transformation in the awareness of each and every one of us is required.

廃棄の闇と浄化の光 ― 産業廃棄物の不法投棄とその再生への道
廃棄の闇と浄化の光 ― 産業廃棄物の不法投棄とその再生への道
荒れ果てた土地に積み重なる不法投棄の影。静かに、しかし確実に広がる環境の傷跡は、やがて社会の目に晒されることとなった。2003年1月20日、環境省はこの闇を払うべく、警察OB、弁護士、測量士ら専門家を集めた調査チームを設置した。
全国に点在する670か所もの不法投棄現場。その原状回復には900億円という莫大な費用が必要と試算された。誰が責任を負うべきか。誰が環境を汚し、そして誰がその清浄を取り戻すのか。関与者の特定と負担額の算定が進められ、また、自治体の負担を軽減する策も検討された。
そして、闇に立ち向かう新たな剣が打ち立てられた。2003年2月20日、「特定産業廃棄物に起因する支障の除去等に関する特別措置法」、通称「産廃特措法」が閣議決定された。この法律は、過去10年間に集中した不法投棄の原状回復を推進し、排出事業者や運搬業者の責任を厳しく追及するものだった。
さらには、汚染された大地を再生するためのもう一つの枠組みとして、2003年2月、土壌汚染対策法が施行された。有害物質による汚染が確認された土地の所有者には浄化措置が義務付けられ、都道府県知事は健康被害の恐れがある場合、汚染除去を命じる権限を持つこととなった。
さらに、廃棄を抑制する新たな仕組みとして、2003年1月6日、奈良県では「産業廃棄物税（仮称）」の導入が検討された。最終処分場へ搬入される廃棄物1トンあたり1000円の課税を行い、その税収を不法投棄抑制や環境保全策の財源とするという試みだった。
こうして、不法投棄の闇に光を差し込むべく、政府は法整備と環境対策に動き出した。しかし、廃棄を巡る問題は依然として尽きることがない。環境犯罪の根を断つためには、制度の強化のみならず、私たち一人ひとりの意識の変革が求められている。

Recycling Mine Bark Project by the Japan Mining Association - June 1995 **Recycling Mine Bark Project: Revitalizing Regional Mines and Promoting Resource Circulation**
Recycling Mine Bark Project by the Japan Mining Association - June 1995 **Recycling Mine Bark Project: Revitalizing Regional Mines and Promoting Resource Circulation**
The Japan Mining Association launched the "Recycling Mine Bark Project" in 1995 to efficiently recycle household appliances and industrial waste within Japan. This plan aims to utilize closed mines and surplus infrastructure as recycling centers to carry out low-cost and efficient recycling. Notably, regions such as the Osarizawa Mine in Aomori Prefecture and the Kosaka Mine in Akita Prefecture are being repurposed to promote local economic revitalization alongside environmental protection.
The project involves recovering valuable metals such as copper, aluminum, iron, and gold from discarded household appliances and industrial equipment. Advanced sorting and processing technologies have been introduced, boosting Japan's recycling rate and encouraging the reuse of scarce resources. For example, around 20,000 tons of copper and 10,000 tons of aluminum are recovered annually from used refrigerators, air conditioners, and televisions.
In addition, major companies within the Japan Mining Association, including Mitsui Mining & Smelting and Sumitomo Metal Mining, are actively participating in this project, utilizing their refining technologies to streamline the recycling process. Mitsui Mining & Smelting, for example, processes several thousand tons of waste annually at its recycling facility in Akita Prefecture, focusing on the recovery and reuse of precious metals.
Collaborating with Japan's Ministry of the Environment, the project has expanded nationwide, and efficient waste collection and processing have been promoted in cooperation with local governments. As a result, tens of thousands of tons of industrial waste are recycled annually across Japan, contributing to cost reductions in domestic waste management. The Recycling Mine Bark Project has garnered international attention as a sustainable resource management model amid concerns about resource depletion, with expectations for future technology transfers abroad.

Illegal Chemical Discharge Incident in Yokohama City, Kanagawa Prefecture - 2003 Overview: In 2003, it was discovered that a company based in Yokohama City, Kanagawa Prefecture, with operations in the Kanto region, had illegally discharged specified chemical substances such as chromium and mercury. This incident raised concerns about impacts on surrounding residents and the environment. Yokohama City instructed the company to strictly implement waste management based on environmental standards and strengthened its monitoring system. Particularly, this illegal discharge affected the Tsurumi River within Yokohama City, raising concerns about water pollution and damage to the ecosystem. Details: The company in question had chromium concentrations of 15 milligrams per liter and mercury concentrations of 0.08 milligrams per liter in the waste liquid generated during its manufacturing process. These levels exceeded the standard values by three times and two times, respectively. Thi
s wastewater was not properly treated and was directly discharged into the Tsurumi River, resulting in deteriorated water quality. Consequently, mass fish deaths were reported near the Tsurumi River, prompting local environmental groups to demand a swift investigation. The investigation confirmed the exceedances, leading to concerns among nearby residents about drinking water safety and potential health impacts. Corporate Involvement and Penalties:
Furthermore, it was revealed that the company had manipulated discharge concentration data between 2002 and 2003, falsifying records to make actual discharge levels appear lower than they were. Consequently, local authorities and the Ministry of the Environment plan to take stringent measures, imposing fines of up to 50 million yen on the company and considering criminal penalties, including imprisonment, for those involved. Additionally, the company's name was made public following this incident, causing significant shock throughout the local community.
Response and Monitoring System: In response to this incident, Yokohama City strengthened its monitoring system for surrounding companies by installing 10 additional surveillance cameras and increasing water quality monitoring from once a month to once a week. The Ministry of the Environment also plans to tighten nationwide regulations on chemical substance emissions going forward and revise standards to prevent similar illegal acts from recurring.
Conclusion: This incident demonstrates how illegal activities by a specific company can severely impact the local environment and residents' health. To prevent recurrence, strict enforcement of the law and further strengthening of monitoring systems are essential.

神奈川県横浜市における化学物質違法排出事件 - 2003年
神奈川県横浜市における化学物質違法排出事件 - 2003年
概要:
2003年、関東地方に拠点を持つ神奈川県横浜市の企業が、クロムや水銀などの特定化学物質を違法に排出していたことが発覚しました。この事件により、周辺の住民や環境への影響が懸念され、横浜市はこの企業に対し環境基準に基づいた廃棄物管理を徹底するよう指導し、監視体制を強化しました。特に、この違法排出は横浜市内の鶴見川に影響を及ぼし、水質汚染と生態系の損害が懸念されています。
詳細:
問題の企業は、製造過程で発生する廃液に含まれるクロム濃度が1リットルあたり15ミリグラム、水銀濃度が1リットルあたり0.08ミリグラムと、基準値をそれぞれ3倍および2倍上回っていました。これらの廃液は適切に処理されず、直接排水として鶴見川に流され、結果として川の水質が悪化しました。これにより、鶴見川付近では魚類の大量死が報告され、地元の環境保護団体が迅速な調査を要請しました。調査により基準値超過が確認され、周辺住民も飲料水や健康被害についての懸念を抱く事態となっています。
企業の関与と罰則:
さらに、この企業は2002年から2003年にかけて排出濃度のデータを操作し、実際の排出量よりも低く見せるよう偽装していたことが判明しました。これにより、地方自治体と環境省は厳しい措置を取る方針で、企業に対し最大5000万円の罰金を科し、関係者には懲役刑を含む刑事罰も検討されています。また、この事件を受けて企業名が公表され、地域社会全体に大きな衝撃を与えています。
対応と監視体制:
横浜市は、今回の事件を受けて監視カメラを10台増設し、水質モニタリングを月1回から週1回に増やすなど、周辺企業への監視体制を強化しました。環境省も今後、化学物質排出に関する全国的な規制の厳格化を進め、同様の違法行為が再発しないよう基準を改定する方針です。
結論:
この事件は、特定企業の違法行為が地域の環境と住民の健康に深刻な影響を与えたものであり、再発防止のため、法の厳格な適用と監視体制のさらなる強化が求められています。

The Issue of Industrial Waste in the Suburbs of Beijing and the Government's Response - 2021 In the 2020s, the issue of industrial waste in the suburbs of Beijing remains serious. Cities surrounding Beijing, such as Tangshan and Langfang in Hebei Province, are industrial hubs, and frequent reports of illegal dumping of industrial waste from steel and chemical industries have been made. Large companies such as Tangshan Iron and Steel Group and Hebei Iron and Steel Group operate in these areas, and improper waste management has been pointed out. In particular, in 2021, about 1,500 tons of toxic waste were illegally dumped in Langfang. The waste contained heavy metals such as lead, cadmium, and arsenic, which severely affected the soil and water quality. This incident posed a direct threat to local farmland and drinking water, significantly endangering the environment and residents' health. Additionally, in the area surrounding Beijing, plastic waste and electronic waste (E-wast
e) have not been properly disposed of. In 2022, the Northern China Electronics Recycling Association was fined for illegally dumping over 300 tons of electronic waste.
In response to these issues, the Chinese government enacted the "Solid Waste Pollution Prevention Law" in 2021, imposing strict fines on companies that engage in illegal dumping. Under this law, companies can be fined up to 5 million yuan (approximately 7.5 million yen), and the obligation to restore the environment has been strengthened. In Beijing, the management of waste imports and processing has also been tightened, with strict monitoring of illegal waste trading. Thus, in the 2020s, the industrial waste issue in the suburbs of Beijing continues to have a major impact on the local community, and cooperation between the Chinese government and local companies is urgently needed to improve the situation.

History and Current Status of Russia's Ocean Dumping of Radioactive Waste (2020s) ### 1. Historical Background Since the Soviet era, Russia has continued the practice of dumping radioactive waste into the Arctic Barents Sea and Kara Sea. From the late 1960s to the late 1980s, approximately 18,000 containers of radioactive waste were sunk in these waters. This includes the nuclear submarines K-27 and K-159. K-27 was intentionally scrapped in 1982, while K-159 sank during a towing operation in 2003. K-27 lies in 33 meters of shallow water, and K-159 rests at a depth of 200 meters, raising concerns about the environmental risks each poses.

K-27 lies in 33 meters of shallow water, and K-159 rests at a depth of 200 meters, raising concerns about the environmental risks each poses.
At the time, the ocean dumping of this waste followed a "out of sight, out of mind" policy that downplayed environmental impacts. Although the London Convention banned ocean dumping of radioactive waste in 1993, another 11 reactors were dumped at sea by 1994, some containing spent nuclear fuel.
### 2. Current Status and Efforts in the 2020s In recent years, Russia has initiated a plan to remove these wastes. Led by Rosatom, this plan aims to remove six major wastes over eight years. The removal costs are estimated at 278 million euros (approximately 4.5 billion yen), with 57.5 million euros earmarked for raising K-159.
To date, the Norwegian government has contributed 150 million euros to support nuclear safety projects in the Arctic. However, the removal operations are technically complex and carry risks of radioactive leakage, demanding careful execution. K-27 is often referred to as a "radioactive time bomb," necessitating urgent countermeasures.
### 3. Future Challenges This issue has the potential for long-term impacts on the entire Arctic ecosystem and fishery resources, making international cooperation essential. Led by Russia, this project is expected to become a significant model case for Arctic environmental protection through collaboration with the international community.

ロシアによる放射性廃棄物の海洋投棄の歴史と現状（2020年代）
ロシアによる放射性廃棄物の海洋投棄の歴史と現状（2020年代）
### 1. 歴史的背景
ロシアでは旧ソ連時代から、北極圏のバレンツ海やカラ海に放射性廃棄物を投棄する慣行が続いていました。1960年代後半から1980年代後半にかけて、約18000個の放射性物質を含む廃棄物がこれらの海域に沈められました。その中には、原子力潜水艦K-27やK-159が含まれています。K-27は1982年に故意に廃棄され、K-159は2003年の曳航作業中に沈没しました。K-27は33メートルの浅い海域、K-159は200メートルの深さに沈んでおり、それぞれが環境に与えるリスクが懸念されています。
当時、これらの廃棄物の海洋投棄は、環境への影響を軽視する「見えないところに置く」という方針で行われました。ロンドン条約が1993年に放射性廃棄物の海洋投棄を禁止しましたが、1994年までにさらに11基の原子炉が海中に捨てられ、一部には使用済み核燃料も含まれていました。
### 2. 2020年代の現状と取り組み
近年、ロシアはこれらの廃棄物の撤去計画を開始しました。ロスアトム（Rosatom）が主導するこの計画では、8年間で6つの主要な廃棄物を撤去する予定です。撤去のためのコストは278百万ユーロ（約45億円）に上り、そのうちK-159の引き揚げには57.5百万ユーロが見積もられています。
これまでにノルウェー政府は1.5億ユーロを拠出し、北極圏の核安全プロジェクトを支援しています。しかし、撤去作業は技術的に複雑であり、放射能漏れのリスクを伴うため、慎重な実施が求められます。K-27は「放射性の時限爆弾」とも言われ、緊急な対策が必要とされています。
### 3. 今後の課題
この問題は、北極圏全体の生態系と漁業資源に長期的な影響を及ぼす可能性があり、国際的な協力が不可欠です。ロシアが率いるこのプロジェクトは、国際社会との協力を通じて、北極圏の環境保護における重要なモデルケースとなることが期待されています。

Then a rat of renown, very ready of tongue. Said, for a sovereign help to themselves, " Some cits have I seen, in the city of London, 160 Wear chains on their necks of the choicest gold. Or collars of crafty work ;
uncoupled they go Both in warren and waste, as their will inclines, And elsewhere at odd times, as I hear tell. If they bore each a bell, by its ringing, me thinketh, 165 One might wit where they were, and away soon run ! Right so," quoth the rat, " doth reason suggest To buy a bell of brass or of bright silver. AH the rout of great rats to his reasons assented, 175 But when bought was the bell, and well bound on the collar, Not a rat in the rout, for the realm of all France, Durst bind the said bell about the cat's neck, Nor hang it beside him, all England to win ! They owned they were cowards, and their counsel weak ; 1 80 So their labour was lost, and all their long study. To be bound on a collar, for our common profit, On the cat's neck to hang ; then each hearer can tell 170 If he rambles or rests him, or runs out to play !
When mild is his mood, we can move as we list And appear in his presence, when playful and pleased. Or, when angry, beware ; and away will we run ! " In Piers Plowman, the scene known as the "rats and the cat" presents a group of rats holding a council to find a way to escape the cat's domination. A prominent, quick-tongued rat rises and offers an example drawn from what the translator renders as "the city of London," referring to wealthy citizens who wear gold chains and finely crafted collars and seem to move about freely. Borrowing this image, the rat argues that if the cat were made to wear a bell, the ringing would reveal his movements and allow the rats to flee in time. All the rats agree with the reasoning and even decide to purchase a brass or silver bell. Yet when the moment comes to attach the bell to the cat's neck, not a single rat dares to do it, even if promised the whole of France or all of England as a reward. Confronted with their own fear, the
rats admit that their counsel is weak and that their long deliberations are useless. Although the proposal is logically sound, no one is willing to face the danger required to enact it. The episode thus shows how political reform collapses when no one will take responsibility for difficult action. As an allegory, this scene functions as a sharp satire of the weakness and timidity of contemporary urban government, especially the civic politics of London and its citizen-elite, who discuss reforms but shrink from challenging real power.

In Piers Plowman, the scene known as the "rats and the cat" presents a
group of rats holding a council to find a way to escape the cat's
domination. A prominent, quick-tongued rat rises and offers an example
drawn from what the translator renders as "the city of London,"
referring to wealthy citizens who wear gold chains and finely crafted
collars and seem to move about freely. Borrowing this image, the rat
argues that if the cat were made to wear a bell, the ringing would
reveal his movements and allow the rats to flee in time. All the rats
agree with the reasoning and even decide to purchase a brass or silver
bell. Yet when the moment comes to attach the bell to the cat's neck,
not a single rat dares to do it, even if promised the whole of France or

Hokkaido Electric Power's Challenge in Renewable Energy - December 2001 Hokkaido Electric Power has focused on introducing renewable energy, developing an energy policy centered particularly on wind power generation. By 2001, it had set an annual power purchase target of 150,000 kilowatts, deepening cooperation with local power producers while advancing research and development to ensure stable energy supply. Specifically, it overcame the challenges of fluctuating wind power generation by introducing battery storage systems and improving the efficiency of the power network. Trends in the 2010s During the 2010s, Hokkaido Electric Power expanded its adoption of renewable energy, constructing new wind farms in Tomamae Town and Rumoi City. Its annual power purchase volume increased to approximately 500,000 kilowatts. Furthermore, the introduction of the Feed-in Tariff (FIT) system encouraged participation from local businesses. In collaboration with Hitachi, Ltd. and Sumitomo Ele
ctric Industries, Ltd., demonstration experiments were conducted on large-capacity storage batteries and power grid efficiency. This significantly reduced barriers to introducing wind power generation. Current Status in the 2020s
Entering the 2020s, Hokkaido Electric Power has set a target to achieve a 40% renewable energy ratio by 2030 and is actively implementing measures. Projects are underway, including the Ishikari Bay New Port Wind Farm (annual generation capacity of approximately 600,000 kilowatts) and an offshore wind power plan in Rumoi City. Research into next-generation energy technologies utilizing ammonia and hydrogen is also being pursued, forming a key pillar of the energy transition. Regarding CO2 reduction targets, the company aims to reduce emissions by approximately 2 million tons annually, contributing to sustainable development both regionally and nationally. Supplementary Information from Related Sources - Property Tax Revenue and Job Creation: According to a report by the Japan Wind Power Association (JWPA), Hokkaido accounts for over 30% of Japan's total wind power capacity. Property tax revenue from this sector exceeds ¥10 billion annually. This has stabilized the regional ec
onomy and created approximately 1,500 jobs. - Renewable Energy Penetration Rate: Statistics from the Ministry of Economy, Trade and Industry indicate Hokkaido's renewable energy penetration rate exceeded the national average at 35% (as of 2020). This demonstrates Hokkaido Electric Power's leading role in renewable energy adoption.
- Joint Research Outcomes: Presentations by Hitachi and Sumitomo Electric Industries indicate that transmission efficiency improvements and energy storage technologies support the stable supply of wind power. These technologies have been confirmed as applicable to other regions. Sources - Hokkaido Electric Power Co., Inc.

"Black Tears Floating on the Sea"—Memories of the Tanker Accident off Shimane - January 1997
"Black Tears Floating on the Sea"—Memories of the Tanker Accident off Shimane - January 1997
In January 1997, the Russian tanker "Nahodka" caused an oil spill off the coast of Shimane Prefecture, staining the Sea of Japan with black tears. Approximately 6,000 tons of crude oil spilled, severely impacting the Oki Islands and the coast of Tottori Prefecture. The fishing industry suffered devastating blows, particularly to the abalone and turban shell aquaculture industries, and tourism also sustained significant damage.
To clean the polluted sandy beaches, a total of 40,000 local residents and volunteers gathered from across the nation worked in the cold winds. While the Japanese government mobilized oil recovery ships and helicopters and promoted the use of oil absorbents, complete recovery required a long period. Furthermore, through cooperation with the Russian government and the International Maritime Organization (IMO), discussions were held to investigate the cause of the accident and prevent recurrence. This tragedy served as a wake-up call, reinforcing the importance of marine environmental protection and becoming a catalyst for stricter regulations both domestically and internationally.

Construction of Kitakyushu City's Waste-to-Energy Plant and Development in the 2020s Kitakyushu City's "Shin-Kōgosaki Plant," which began operations in 1998, was established as one of Japan's largest waste-to-energy facilities. The facility can process 810 tons of waste per day, achieving annual waste treatment of approximately 295,650 tons. Its maximum power generation capacity is 36,300 kilowatts per hour, enabling an annual electricity supply of about 260,000 megawatt-hours. This is equivalent to the annual electricity consumption of approximately 15,000 households. The generated electricity is sold to Kyushu Electric Power, with projected annual revenue of about 2 billion yen.

This is equivalent to the annual electricity consumption of approximately 15,000 households. The generated electricity is sold to Kyushu Electric Power, with projected annual revenue of about 2 billion yen.
The facility incorporates a high-efficiency waste incineration system provided by Ebara Corporation, improving waste combustion efficiency and reducing carbon dioxide emissions by approximately 30% compared to conventional incineration facilities. Specifically, annual CO₂ emissions are projected to be reduced by approximately 80,000 tons. An exhaust gas treatment system suppresses harmful substances such as dioxins and nitrogen oxides (NOx) to levels below environmental standards. Furthermore, approximately 40,000 tons of incineration ash are generated annually as a byproduct of incineration. This ash is reused as construction materials and road paving materials, promoting the circular use of resources. Through the operation of this facility, Kitakyushu City has achieved both proper waste treatment and the effective utilization of energy resources, significantly contributing to reducing the environmental burden on the region.
Even in the 2020s, the Kōgosaki Plant continues to operate as a highly efficient waste-to-energy facility, incorporating the latest technologies. This facility processes 810 tons of waste per day, totaling approximately 169,900 tons annually. Its maximum power generation capacity is 17,200 kilowatts, achieving an annual power generation output of about 91,300 megawatt-hours. This power generation is equivalent to the annual electricity consumption of approximately 25,000 households. By selling approximately 55,800 megawatt-hours annually to Kyushu Electric Power, it generates annual revenue of approximately 2 billion yen.
Additionally, the exhaust gas treatment equipment has been upgraded to reduce environmental impact. Dioxin emissions are maintained at 0.0016 ng-TEQ/g, significantly below the legal standard of 3 ng-TEQ/g. Furthermore, the ash thermal reduction rate is 2.2%, substantially lower than the standard value of 10%, achieving both safety and reduced environmental burden.
In 2022, a demonstration experiment utilizing AI for waste identification commenced, alongside efforts to prevent the mixing of hazardous materials such as cassette gas cylinders. This AI technology reduces the risk of fire within the facility, enhancing safety. Through such technological innovation and community initiatives, the Kōgosaki Plant continues to make significant contributions to regional energy supply and environmental conservation by simultaneously achieving waste processing and power generation.
The facility incorporates a high-efficiency waste incineration system provided by Ebara Corporation, improving waste combustion efficiency and reducing carbon dioxide emissions by approximately 30% compared to conventional incineration facilities. Specifically, annual CO₂ emissions are projected to be reduced by approximately 80,000 tons. An exhaust gas treatment system suppresses harmful substances such as dioxins and nitrogen oxides (NOx) to levels below environmental standards. Furthermore, approximately 40,000 tons of incineration ash are generated annually as a byproduct of incineration. This ash is reused as construction materials and road paving materials, promoting the circular use of resources. Through the operation of this facility, Kitakyushu City has achieved both proper waste treatment and the effective utilization of energy resources, significantly contributing to reducing the environmental burden on the region.
Even in the 2020s, the Kōgosaki Plant continues to operate as a highly efficient waste-to-energy facility, incorporating the latest technologies. This facility processes 810 tons of waste per day, totaling approximately 169,900 tons annually. Its maximum power generation capacity is 17,200 kilowatts, achieving an annual power generation output of about 91,300 megawatt-hours. This power generation is equivalent to the annual electricity consumption of approximately 25,000 households. By selling approximately 55,800 megawatt-hours annually to Kyushu Electric Power, it generates annual revenue of approximately 2 billion yen.
Additionally, the exhaust gas treatment equipment has been upgraded to reduce environmental impact. Dioxin emissions are maintained at 0.0016 ng-TEQ/g, significantly below the legal standard of 3 ng-TEQ/g. Furthermore, the ash thermal reduction rate is 2.2%, substantially lower than the standard value of 10%, achieving both safety and reduced environmental burden.

History and Current Status of Septic Tank Installation in Japan: Progress and Challenges from the 1990s to the 2020s
From the 1990s, septic tank installation progressed in Japan. Ordinances and plans around Kojima Lake in Okayama Prefecture and the Yoro River basin in Chiba Prefecture promoted regional water quality improvement. In the 2000s, companies like Fujiclean Industries and Kubota developed advanced treatment septic tanks, leading to the widespread adoption of nitrogen and phosphorus removal technologies. The 2010s saw increased adoption in post-Great East Japan Earthquake reconstruction housing and for protecting tourist areas. By the 2020s, the nationwide installed base reached 7,516,864 units, with 35.6% being advanced treatment types. However, regional disparities and challenges in maintenance and management remain. Further technological innovation and promotion of adoption are required going forward.

Approximately 50,000 people participated in protests in Germany, and a boycott of Shell gas stations was launched in Norway, causing Shell's sales to drop by up to 40% and dealing a serious blow to the company. In response to this situation, Shell temporarily suspended its dumping plans and moored the facility in Norwegian waters.
This incident brought global attention to environmental protection activities and symbolized the growing social awareness of corporate environmental responsibility. In particular, the Brent Spar incident demonstrated the importance of the international community acting in concert on environmental issues and became a symbolic event in international environmental protection activities. Furthermore, the emphasis on the environmental impact of ocean dumping led to significantly stricter standards and regulations for waste disposal in the oil industry thereafter.
Furthermore, regarding the relationship between corporations and society, the Brent Spar incident underscored the importance of "Corporate Social Responsibility (CSR)." Subsequently, many companies began incorporating sustainable environmental measures into their strategies. From an environmental protection perspective, this incident became a historic turning point that profoundly altered the nature of business. 【File Name: 15-1995-10-15.pdf】

ブレント・スパー貯蔵施設の処分方法公募-1995年10月
ブレント・スパー貯蔵施設の処分方法公募-1995年10月
北海油田に設置されていたブレント・スパー石油貯蔵施設（高さ約140メートル、重量約1万4600トン、直径29メートル）は、シェル・グループが所有し、年間約30万バレルの石油を貯蔵していました。1995年、英国政府はこの施設の北大西洋への海中投棄を許可しましたが、約1000トンの残留油が含まれていることが判明し、環境保護団体グリーンピースやドイツ、ノルウェー、デンマークなど欧州諸国から強い反発を受けました。
ドイツでは約5万人が抗議活動に参加し、ノルウェーではシェルのガソリンスタンドに対する不買運動が展開され、シェルの売上は最大40%減少するなど、企業にとっても重大な打撃を受けました。この事態を受け、シェルは投棄計画を一時中止し、施設をノルウェーの海域に係留しました。
この事件は、環境保護活動が世界的に注目される契機となり、企業の環境責任に対する社会的意識の高まりを象徴しました。特にブレント・スパー事件は、国際社会が環境問題に対して協調して行動する重要性を示し、国際的な環境保護活動の象徴的な出来事となりました。また、海洋への投棄が環境に与える影響が強調されたことで、以後の石油業界における廃棄物処理の基準や規制が大幅に厳格化されるきっかけとなりました。
さらに、企業と社会の関係においても、ブレント・スパー事件は「企業の社会的責任（CSR）」の重要性を強調し、以降、多くの企業が持続可能な環境対策を戦略に組み込むようになりました。この事件は、環境保護の観点からもビジネスの在り方を大きく変える歴史的な転換点となりました。

Illegal Dumping of FRP Vessels - Nationwide in Japan - History and Current Status from 2004 to the 2020s FRP (Fiber Reinforced Plastic) pleasure boats gained popularity due to their durability and light weight, but their disposal has become a significant issue. By 2004, approximately 5,000 vessels were being discarded annually, with about 1,000 illegally dumped along coastlines and riverbanks. This illegal dumping caused severe environmental impacts, including the deterioration of marine ecosystems and landscape destruction. In response, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) began designing systems to promote FRP boat recycling. Efforts advanced to improve dismantling and crushing technologies for discarded vessels and establish dedicated recycling facilities. Additionally, campaigns to prevent illegal dumping were conducted in collaboration with local governments, and mechanisms requiring vessel owners to bear part of the recycling costs were als
o considered. However, ensuring the profitability of recycling operations remained a challenge. While development progressed on technologies to reuse discarded FRP as building materials or fuel, widespread implementation took time.
During the 2010s, efforts to resolve the FRP waste vessel problem intensified. In 2015, the "National FRP Waste Vessel Recycling Promotion Council" was established, advancing industry-wide initiatives. Specifically, shredding technology for used FRP significantly improved, leading to increased cases of its use as recycled material in road paving and construction materials. Furthermore, the government expanded subsidies for vessel disposal to a maximum of 500,000 yen per case and launched model projects in collaboration with local governments. As a result, by 2018, the proper disposal rate for FRP vessels reached 65%. However, approximately 35% (about 1,750 vessels annually) remained untreated or illegally dumped.
Entering the 2020s, reports indicate that while approximately 6,000 vessels are scrapped annually, around 800 are illegally dumped without proper processing. In response, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) established over 10 dedicated dismantling facilities nationwide, creating a system capable of processing over 2,000 scrap vessels annually. Furthermore, companies like Mitsubishi Chemical and Sumitomo Chemical have developed chemical recycling technologies, advancing efforts to reuse waste FRP as building materials and fuel. Additionally, municipalities along the Seto Inland Sea enacted the "Seto Inland Sea Waste Vessel Management Ordinance" in 2020, mandating notification to owners and introducing penalties. This reduced the abandonment of waste vessels by over 10% annually. However, the high average disposal cost of over ¥200,000 per vessel remains a persistent challenge. Internationally, efforts to share waste ship recycling technology wi
th neighboring countries like South Korea and the Philippines are advancing. The FRP waste ship issue is positioned as part of reducing marine plastic pollution and is a critical challenge for protecting the marine environment. While technological innovation and strengthened regulations have brought some improvement, the need for cost reduction and increased owner awareness remains unchanged.

FRP廃船の不法投棄問題 - 日本全国 - 2004年から2020年代の歴史と現状
FRP廃船の不法投棄問題 - 日本全国 - 2004年から2020年代の歴史と現状
FRP（繊維強化プラスチック）製プレジャーボートは、耐久性と軽量性から普及しましたが、その廃棄処理が課題となっています。2004年時点では、年間約5000隻が廃棄され、そのうち約1000隻が沿岸部や河川敷で不法投棄されていました。不法投棄は環境への深刻な影響を及ぼし、海洋生態系の悪化や景観破壊が問題視されました。
これに対し、国土交通省はFRP廃船のリサイクル推進に向けた制度設計を開始。廃船の解体・粉砕技術の向上や専用リサイクル施設の整備が進められました。また、自治体と連携した不法投棄防止キャンペーンが展開され、船舶所有者にリサイクル費用の一部負担を求める仕組みも検討されました。しかし、リサイクル事業の採算性確保が課題であり、廃FRPの建材や燃料としての再利用技術の開発が進む一方、広範な導入には時間を要しました。
2010年代には、FRP廃船問題の解決に向けた動きがさらに活発化しました。2015年には「全国FRP廃船リサイクル推進協議会」が設立され、業界全体での取り組みが進みました。具体的には、使用済みFRPの粉砕技術が大幅に改善され、リサイクル材として道路舗装や建設資材に利用される事例が増加しました。また、政府は廃船処理の補助金を1件あたり最大50万円に拡充し、自治体と連携したモデルプロジェクトを展開。その結果、2018年時点でFRP廃船の適切処理率は65％に達しましたが、依然として約35％（年間約1750隻）が未処理または不法投棄されている状況でした。
2020年代に入ると、年間約6000隻が廃棄される中、約800隻が適切に処理されないまま不法投棄されているとの報告があります。これを受けて、国土交通省は全国で10カ所以上の専用解体施設を新設し、年間2000隻以上の廃船を処理可能な体制を整備しました。さらに、三菱ケミカルや住友化学などの企業が化学リサイクル技術を開発し、廃FRPを建材や燃料として再利用する取り組みが進められています。
また、瀬戸内海沿岸の自治体では、2020年に「瀬戸内海廃船管理条例」を施行し、所有者への通知義務化やペナルティの導入を実施。これにより、廃船の放置が年間10％以上減少しました。一方で、処理コストが平均1隻あたり20万円以上かかる点が引き続き課題です。
国際的にも、韓国やフィリピンなどの近隣諸国と廃船リサイクル技術の共有が進められています。FRP廃船問題は、海洋プラスチック削減の一環として位置づけられ、海洋環境保護のための重要な課題となっています。技術革新や制度強化により一定の改善が見られるものの、コスト削減や所有者意識の向上が求められる状況は変わりません。

Strengthening Waste Dumping Regulations at the North Sea Protection Conference - August 1995 At the North Sea Protection Conference held in 1995, it was agreed to completely ban the dumping of hazardous waste into the North Sea by 2020. This agreement aims for a significant reduction in the over 10,000 tons of hazardous waste currently dumped into the North Sea annually. The targeted substances include heavy metals such as lead, mercury, and cadmium, as well as highly toxic chemicals like PCBs (polychlorinated biphenyls) and dioxins. These pose severe adverse effects on marine ecosystems, particularly burdening fishery resources.

These pose severe adverse effects on marine ecosystems, particularly burdening fishery resources.
North Sea coastal nations including France, Germany, Denmark, the Netherlands, and Norway have established a policy to gradually reduce dumping volumes by 2020 and ultimately achieve zero dumping to meet these reduction targets. Meanwhile, the UK, facing pressure from major domestic chemical companies like ICL (Imperial Chemical Industries), Union Carbide, and pharmaceutical firms, did not sign up to the complete ban on dumping. Consequently, the UK is expected to continue dumping approximately 2,000 tons of waste into the North Sea annually.
This agreement is expected to significantly impact the improvement of North Sea water quality. France and Germany have announced plans to allocate a budget of 500 million euros (approximately 65 billion yen) for the development of waste recycling facilities. Furthermore, the Norwegian government intends to invest 10 million euros (approximately 1.3 billion yen) annually in developing waste treatment technologies, advancing efforts toward the goal of zero ocean dumping.
While these North Sea protection initiatives are expected to benefit fishery resources and tourism, the chemical industry is being called upon to transition toward sustainable management practices, including waste recycling and harmless treatment.

北海保護会議廃棄物投棄規制強化 - 1995年8月
北海保護会議廃棄物投棄規制強化 - 1995年8月
1995年に開かれた北海保護会議では、北海への危険廃棄物投棄を2020年までに完全に禁止することが合意されました。この合意により、現在、年間で約10000トン以上が北海に投棄されている有害廃棄物の大幅な削減が目指されています。対象となるのは、鉛、水銀、カドミウムなどの重金属に加え、PCB（ポリ塩化ビフェニル）やダイオキシンといった極めて毒性の強い化学物質です。これらは海洋生態系への悪影響が深刻で、特に漁業資源への負担が顕著です。
フランスやドイツ、デンマーク、オランダ、ノルウェーなどの北海沿岸諸国は、こうした有害廃棄物の削減目標を達成するため、2020年までに投棄量を段階的に縮小し、最終的にはゼロにする方針を固めています。一方、イギリスは国内の主要化学企業であるICL（インペリアル・ケミカル・インダストリーズ）やユニオン・カーバイド、製薬企業などの業界からの圧力を受け、投棄の完全停止に調印しませんでした。これにより、イギリスは年間約2000トンの廃棄物を引き続き北海に投棄する可能性が指摘されています。
この合意は、北海の水質改善に大きな影響を与えると期待されており、フランスとドイツでは廃棄物のリサイクル施設の整備に5億ユーロ（約650億円）の予算を計上する計画が発表されています。また、ノルウェー政府は廃棄物の処理技術開発に年1000万ユーロ（約13億円）を投入し、海洋投棄ゼロの目標に向けた取り組みを進める方針です。
このように、北海保護の取り組みは漁業資源の保護や観光業への好影響を期待される一方、化学業界には廃棄物のリサイクルや無害化処理など、持続可能な経営への転換が求められています。

The Evolution of U.S. Grain Supply and Demand - From the 1990s to the 2020s
The Evolution of U.S. Grain Supply and Demand - From the 1990s to the 2020s
1990s According to a Worldwatch Institute report, grain prices rose 39% over the three years ending in 1996. This was driven by China's rapidly increasing feed demand, particularly the expansion of grain imports accompanying growth in meat production. While U.S. grain exports increased, domestic stockpiles were declining, creating a need for stabilization in the international market.
2000s In the early 2000s, corn demand surged due to the expansion of bioethanol production. This triggered a sharp rise in grain prices, making food price inflation a global issue. Simultaneously, major grain producers like Brazil and Argentina increased their exports, intensifying competition in the U.S. export market.
2010s: During the 2010s, China established itself as the world's largest grain importer. U.S. soybeans and corn became central supplies for China's food security policy. However, U.S.-China trade friction temporarily led China to shift imports to other countries like Brazil. Additionally, climate change impacts caused harvest fluctuations due to floods and droughts, becoming a significant issue.
2020s: Entering the 2020s, ample rainfall in the U.S. Midwest boosted grain production, with bumper corn and soybean harvests projected for 2024. However, high production levels in Brazil and other countries, coupled with intensifying market competition, drove grain prices to their lowest levels since 2020. China's grain demand remains high, with imports reaching 160 million tons in 2023, accounting for a quarter of the global total. American farmers face pressure on profits due to falling prices and are implementing cost-cutting measures. Furthermore, concerns exist that Brazil is expanding its share of the Chinese market, potentially reducing the U.S.'s export market share.

China's grain demand remains high, with imports reaching 160 million tons in 2023, accounting for a quarter of the global total. American farmers face pressure on profits due to falling prices and are implementing cost-cutting measures. Furthermore, concerns exist that Brazil is expanding its share of the Chinese market, potentially reducing the U.S.'s export market share.
アメリカの穀物需給の変遷 - 1990年代から2020年代まで
アメリカの穀物需給の変遷 - 1990年代から2020年代まで
1990年代
ワールドウォッチ研究所の報告によれば、1996年までの3年間で穀物価格が39%上昇。この背景には、中国の飼料需要の急増があり、特に肉類生産の増加に伴う穀物輸入量の拡大が影響していました。アメリカの穀物輸出量は増加する一方で、国内備蓄は減少傾向にあり、国際市場の安定化が求められていました。
2000年代
2000年代初頭には、バイオエタノール生産の拡大に伴い、トウモロコシ需要が急増。これにより、穀物価格の高騰が発生し、食料価格の上昇が世界的な問題として浮上しました。同時に、穀物生産国であるブラジルやアルゼンチンが輸出量を拡大し、アメリカの輸出市場における競争が激化しました。
2010年代
2010年代には、中国が最大の穀物輸入国としての地位を確立。アメリカ産大豆やトウモロコシは、中国の食料安全保障政策の中心的な供給源となりました。しかし、米中貿易摩擦の影響で、一時的に中国がブラジルなど他国からの輸入にシフトする場面も見られました。また、気候変動の影響で、洪水や干ばつによる収穫量の変動が問題となりました。
2020年代
2020年代に入ると、アメリカ中西部では十分な降雨により穀物生産量が増加し、2024年にはトウモロコシと大豆の豊作が予測されています。しかし、ブラジルなど他国の高い生産量や市場競争の激化により、穀物価格は2020年以来の低水準に落ち込みました。中国の穀物需要は依然として高く、2023年には輸入量が1億6000万トンに達し、世界全体の4分の1を占めるまでに拡大。アメリカの農家は価格低下による収益圧迫に直面しつつ、コスト削減策を講じています。また、ブラジルが中国市場でのシェアを拡大し、アメリカの輸出市場シェアの低下が懸念されています。

Annual industrial waste amounts to 400 million tons. Given the shortage of processing facilities and the need for effective resource utilization, the 5R approach (Refine, Reduce, Recycle, Reuse, Reconvert to Energy) is essential.
Annual industrial waste amounts to 400 million tons. Given the shortage of processing facilities and the need for effective resource utilization, the 5R approach (Refine, Reduce, Recycle, Reuse, Reconvert to Energy) is essential.
Sumieito Co., Ltd., headquartered in Himeji City, Hyogo Prefecture, is a leading company in the recycling sector. It has established a unique system as its core business, "turning industrial waste into resources." With approximately 50 employees, the company generates sales of 4.4 billion yen. We spoke with President Eiji Kumano.
Creating resources through technology. The company was founded in 1977. It was established as a management and operations company to prevent secondary pollution when mining companies recovered zinc and other materials from waste. President Kumano joined the company in 1979, two years after its founding. "After graduating from university, I joined the company my uncle managed. Being young at the time, I must admit I felt a bit embarrassed about working with garbage."
Back then, recycling meant zinc recovered from non-ferrous industry waste was reused within that same industry—intra-industry recycling was the norm. Initially, the company followed this conventional approach. However, during the recession triggered by the 1979 Second Oil Crisis, the search for more efficient business methods led to the idea of cross-industry recycling. The recession became the catalyst for challenging conventional wisdom.
"Since it's waste, we'd offer to take it off their hands instead of charging disposal fees. For the generating company, this actually reduced their processing costs. Crucially, this business model also meant the companies receiving the recycled raw materials paid less than for conventional materials. We were relentlessly focused on economic viability from the very start."
When we started the business in 1980 and went to present to cement companies, production-side personnel were reluctant to approve, asking who would take responsibility and how if using waste as raw material affected the product. After much effort, we finally secured an agreement for three trial deliveries of 500 tons each. "However, back then, the companies generating the waste also lacked awareness, and the waste sent from factories presented various challenges. We worked through the night sorting it and somehow managed to deliver it."
After the three trial deliveries, the production manager who had opposed us said, "Mr. Kumano, this is truly an era where we create resources through technology," and decided to accept our solution. "Hearing those words, the sense of inferiority I'd felt about my work vanished. My mindset shifted to recognizing that we were creating resources. Moreover, we were receiving gratitude from both the waste-generating companies and the receiving companies. That was the moment I realized this was work worthy of dedicating my entire life to."
President Kumano was 24 at the time. The business he launched this way gradually expanded its client base, accumulated know-how, and built a system. The recycling system the company established over 20 years is illustrated in the diagram below.
For example, waste from various companies—including sludge and spent solvents—is combined and homogenized into a slurry. This is then used as fuel by cement companies. Similarly, large quantities of eggshells discarded by food companies are utilized as cement raw materials. In other words, within Sumi Eight's recycling system, nothing is truly waste anymore. "For recycling to succeed, three conditions are essential: low cost, stability, and safety.
Through experiencing unfavorable conditions for our company, such as repeated yen appreciation, we have learned what is necessary to meet these conditions. Expanding our network to gather information and efficiently supply recycled raw materials, coupled with deep market knowledge, leads to economic viability. If our recycled raw materials are not superior to current raw materials in both cost and quality, the business has no value. It requires not just the idealistic notion that recycling should be done, but constant competitiveness and adaptation to changing business conditions."
"We aim to become an indispensable company. To date, the company has coordinated recycling for over 1,000 businesses. Beyond its three domestic locations, it established an office in Seoul based on the principle that 'building a wide-ranging recycling coordination network is more rational.' While the company has grown steadily since its founding in 1977, it senses a shift in societal trends over recent years.
The initial catalyst was the 1992 Earth Summit. "Before that, companies were reluctant to publicize that they recycled waste as raw materials. However, since the Summit, the trend has shifted—companies now see it as enhancing their image and are open to promoting it." Furthermore, with initiatives like the Zero Emission Concept proposed by the United Nations University in the late 1990s, the company's efforts seem ahead of their time.
"I suppose you could say the spotlight has turned to what we've been working on, accelerating the trend. However, such initiatives require breaking through the barriers of conventional wisdom, and it's not something one company can do alone. It becomes possible only when symbiotic relationships with other companies are established. Our company doesn't aim to be big or powerful; we strive to be indispensable. With 50 employees, we generate annual sales of 4.4 billion yen.
For a venture company, this size is probably the right fit." Based on this philosophy, the company has not pursued an expansion strategy but has instead focused on maximizing the use of its existing systems. While it operates its own recycling plant, over half of its processing is still outsourced to partners, and transportation and distribution are also contracted out. Establishing a joint venture with the Hitachi Chemical Group in 1995 was also part of this approach.
"We are confident in our information assets, such as our network and know-how. Going forward, technological capability is the challenge. We hope to collaborate with technology-holding entities to create new markets." The company plans to list its shares (over-the-counter) in the fall of 2001. As the global trend toward a zero-waste recycling society, including waste resource recovery, gains momentum, the company's role is likely to become even more significant in the 21st century.

年間4億トンにも上る産業廃棄物。
年間4億トンにも上る産業廃棄物。
処理場不足や資源の有効活用の面からも、5R（Refine、Reduce、Recycle、Reuse、Reconvert to Energy）が求められています。
兵庫・姫路市に本社を置くスミエイト株式会社は、そのリサイクル分野で「産廃を資源に変える」独自のシステムをビジネスとして確立した先進企業であり、社員約50名で44億円を売り上げています。
熊野英介社長にお話を伺いました。
資源を技術で創る。
同社の創立は1977年。
鉱業会社が廃棄物から亜鉛などを回収する際の二次公害防止のための管理運用会社として設立されました。
熊野社長は創業2年後の1979年に入社しました。
「大学卒業後、おじが経営する会社に入社したわけですが、当時は若かったこともあり、正直言ってゴミを扱う仕事を恥ずかしく思う気持ちもありました」。
当時のリサイクルは、非鉄業界の廃棄物から回収された亜鉛は非鉄業界で資源化する、つまり同業種内でのリサイクルが常識でした。
同社においても創立当初はセオリーどおりのリサイクルを行なっていましたが、1979年の第2次オイルショックによる不況下に、より効率のよい事業方式を探る中から異業種間のリサイクルという発想が生まれたといいます。
常識を覆すきっかけになったのが不況だった。
「廃棄物ですから、処理費用がかかるところを逆に引き取らせてくれと申し出るわけで、出す企業にすれば処理コストがかえって安くすむわけです。
この事業で重要なのは再資源化された原料を受け入れる企業にとっても、それまでの原料より安くなること。
経済性には最初から徹底的にこだわりました」。
1980年に事業を始めて問題なく、セメント会社にプレゼンテーションに行ったところ、原料に廃棄物を使って製品に影響がでたら誰がどのように責任を取るのかと、生産サイドの人がなかなかオーケーしてくれませんでした。
やっとのことで、とりあえず500トンを3回試験納入する合意を得ました。
「ところが当時は廃棄物を出す企業にも認識がなく、工場から送られてくる廃棄物には色々難題があります。
徹夜で分別をして、なんとか納入しました」。
3回の試験納入が終わったとき、反対していた生産側の担当者は「熊野さん、これからは資源を技術で創りだす時代なんですね」と言い、受け入れを決めてくれたといいます。
「この言葉を聞いて、それまで持っていた自分の仕事への引け目がなくなり、我々は資源を創りだしているんだという意識に変わりました。
しかも廃棄物の排出企業、受け入れ企業双方から感謝してもらえる。
この仕事は一生を費やすに足りる仕事だと思った瞬間です」。
熊野社長が24歳のときだったといいます。
こうして立ち上げた事業は、少しずつ対象企業を広げ、ノウハウを蓄積し、システムを作りあげてきました。
20年かけて確立した同社のリサイクルシステムは、以下の図のようになっています。
例えば各社から出る廃棄物、含む汚泥、廃溶剤などを複合・均一化してスラリー状にして、セメント会社で燃料として使ったり、食品会社から大量に排出される卵の殻をセメント原料に使ったりします。
つまり、スミエイトのリサイクルシステムの中では、もはや廃棄物と呼ばれるものは存在しません。
「リサイクルの成立には、安価・安定・安全が条件になります。
度重なる円高など、我が社にとっては不利な状況を経験する過程で、条件を満たすには何が必要かを学んできました。
ネットワークを広げて情報収集し再生原料を効率的に供給することに加え、マーケットを熟知することが経済性につながります。
現状の原料より我が社の再生原料の方が経済的にも品質的にも良くなければ、事業の価値がないわけです。
リサイクルすべしという理想論だけでなく、常に競争力と業態変化が必要とされます」。
「なくてはならない会社を目指す。
現在までに同社がリサイクル・コーディネートをした企業は1000社を超え、国内3カ所に加え、 「リサイクルコーディネートネットワークは広範囲で構築したほうが合理的」との考えからソウルにも事業所を設けています。
1977年の創立以来順調に成長してきた同社ですが、ここ数年社会の流れが変わりつつあることを感じています。
最初のきっかけは1992年の地球サミットだった。
「それまでは、企業側も廃棄物をリサイクルして原料としていることは口外したがらない状況でした。
ところがサミット以来、むしろ企業のイメージアップにつながるということで、宣伝してくれても構わないという流れになってきました」。
さらに1990年代後半には国連大学によりゼロエミッション構想が提唱されるなど、同社の取り組みは時代の先取りといった感もあります。
「私たちが取り組んできたことが脚光を浴び、流れが加速してきたといったところでしょうか。
しかし、こうした取り組みはそれまでの常識の壁を打ち破る必要性もあり、1社でできることではありません。
各企業との共生が成り立ってこそ可能になることでしょう。
我社は大きい会社、強い会社ではなく、なくてはならない会社を目指しています。
従業員も50名で年商44億円を上げています。
ベンチャーとしてはこのくらいの人数が適正規模でしょう」。
こうした考えに基づき、会社組織にも拡大路線は取らず、現存のシステムを最大限活かす方向で進んできました。
自社でもリサイクル工場を持っていますが、現在も半分以上は提携先に加工を依頼しており、運搬・流通なども外注しています。
1995年に日立化成グループと合弁会社を設立したのも、こうした発想の一環といえるでしょう。
「我々はネットワークやノウハウなど、情報面には自信があります。
今後は技術力が課題。
技術を持つところと連携して新しい市場を作っていけたらと思っています」。
2001年の秋には株式上場（店頭公開）を予定しています。
廃棄物の再資源化を含むゴミゼロ循環社会への指向が世界的な潮流となる中で、21世紀には同社の役割はさらに大きなものになっているでしょう。
