The Decline and Conservation History of Natural Shorelines - April 1995 The Situation in the 1990s A 1995 survey revealed that natural shorelines across Japan had significantly decreased, shrinking to approximately 55% of their total length. The primary cause of this decline was the increase in artificial shorelines, such as port development and revetment construction. Particularly concerning were the confirmed losses of approximately 40 kilometers in Hokkaido and significant natural coastline disappearances in Akita Prefecture, raising fears of ecological impacts. Natural coastlines serve as vital habitats supporting precious biodiversity, and their loss leads to habitat destruction for numerous plants and animals. In response to this situation, conservation activities and initiatives aimed at restoring natural environments have been advanced, but they have yet to yield sufficient results.
Progress in the 2000s Entering the 2000s, natural restoration projects advanced nationwide. Notably, Chiba Prefecture initiated a tidal flat restoration plan for Tokyo Bay, targeting the recovery of approximately 30 hectares of tidal flats. Furthermore, the Ministry of the Environment enacted the "Natural Restoration Promotion Act" in 2002, establishing a framework for local residents, businesses, and municipalities to collaborate on ecosystem restoration. However, development pressures remained strong, with new landfill projects continuing, creating numerous challenges. Situation in the 2010s By the 2010s, the impacts of climate change compounded the problem, further accelerating the decline of natural coastlines. In Okinawa, coral bleaching spread, leading to increased conservation activities on Ishigaki Island and Miyako Island. The government formulated the "National Biodiversity Strategy 2012-2020," setting clear goals for protecting and restoring natural coastlines. Fur
thermore, the introduction of "coastal erosion control structures designed for coexistence with nature" to curb coastal erosion progressed, but budget constraints and technical challenges hindered these efforts. Current Situation in the 2020s Entering the 2020s, Japan's natural coastlines show a further declining trend. According to a Ministry of the Environment survey, the total length of natural coastline had fallen below approximately 50% of the total by 2023, with the decline continuing. Landfill development is particularly advanced in urban areas like Tokyo Bay and Osaka Bay. The plastic waste problem has also worsened, urgently requiring responses from companies and local governments. On the other hand, companies and organizations such as Nestlé Japan and The Nippon Foundation are actively working to reduce plastic waste and tackle marine debris.
Conclusion The decline of natural coastlines remains a long-term environmental challenge in Japan. Efforts from the 1990s to the 2020s have yielded some results, but further action is essential. Striking a balance between development and conservation to preserve a rich natural environment for future generations is an urgent priority.

自然海岸の減少と保全の歴史-1995年4月
自然海岸の減少と保全の歴史-1995年4月
1990年代の状況
1995年の調査では、日本全国の自然海岸が著しく減少し、総延長の約55％にまで縮小していることが判明しました。この減少の主な要因は、港湾開発や護岸工事などの人工海岸の増加にあります。特に、北海道では約40キロ、秋田県では大幅な自然海岸の消失が確認され、生態系への影響が懸念されています。自然海岸は貴重な生物多様性を支える重要な場であり、その消失は多くの動植物の生息地喪失につながっています。この事態を受け、保護活動や自然環境の復元を目指す取り組みが進められていますが、十分な成果を上げるには至っていません。
2000年代の進展
2000年代に入ると、自然再生事業が全国的に進められました。特に、千葉県では東京湾の干潟再生計画が開始され、約30ヘクタールの干潟復元を目標としました。さらに、環境省は2002年に「自然再生推進法」を制定し、地域住民、企業、自治体が協力して生態系の再生に取り組む枠組みを構築しました。一方で、開発圧力は依然として強く、新たな埋立地造成が継続しており、課題が山積していました。
2010年代の状況
2010年代になると、気候変動の影響も加わり、自然海岸の減少がさらに深刻化しました。沖縄では珊瑚礁の白化現象が広がり、石垣島や宮古島での保全活動が活発化しました。政府は「生物多様性国家戦略2012-2020」を策定し、自然海岸の保護と回復に向けた目標を明確にしました。また、沿岸浸食を抑えるための「自然共生型護岸」の導入が進められましたが、予算不足や技術的課題が取り組みを妨げています。
2020年代の現状
2020年代に入り、日本の自然海岸はさらに減少傾向を示しています。環境省の調査では、2023年時点で自然海岸の総延長は全体の約50％を下回り、減少が続いています。特に東京湾や大阪湾などの都市部では埋立地開発が進行中です。プラスチックごみの問題も深刻化しており、企業や自治体による対応が急がれています。一方で、ネスレ日本や日本財団などの企業や団体が、廃プラスチック削減や海洋ごみ対策に積極的に取り組んでいます。
結論
自然海岸の減少は、日本における環境保護の長期的課題として依然として残されています。1990年代から2020年代にかけての取り組みは一定の成果を上げていますが、さらなる努力が求められています。開発と保全のバランスを取りながら、次世代に豊かな自然環境を残すことが急務です。

Matsumoto City's Heavy Metal Contaminated Soil Remediation Project (2007-2024)
Matsumoto City's Heavy Metal Contaminated Soil Remediation Project (2007-2024)
Since 2007, Matsumoto City has been actively working on a remediation project to address heavy metal contaminated soil. The primary contaminants, lead (Pb) and hexavalent chromium (Cr6+), have been a major concern, with focused investigations and remediation efforts covering approximately 12000 square meters near Matsumoto Station and 8500 square meters in the Asama Onsen area. Shimizu Corporation introduced electrolytic purification technology, reducing the remediation cost of lead-contaminated soil to 30000 yen per ton, achieving an annual processing capacity of approximately 4000 tons. Additionally, DOWA Eco-System introduced iron powder reduction technology, which shortened the remediation period for hexavalent chromium from the conventional 12 weeks to 6 weeks. These initiatives have enabled the treatment of over 80% of the 5000 tons of contaminated soil annually, with remediated land being utilized for constructing hotels and commercial facilities. During the 2010s, fur
ther contaminated areas, such as the Kiri district, were identified and remediated. For instance, in 2015, high concentrations of lead were detected on 1200 square meters of land in the Kiri district, and remediation costs amounted to approximately 300 million yen. During this period, the Matsumoto City Environmental Energy Division conducted over 300 investigations, allocating a budget of approximately 2 billion yen to the remediation projects.
In the 2020s, Matsumoto City has seen an increase in the designation of "areas requiring measures" and "areas requiring notification prior to land alteration" under the Soil Contamination Countermeasures Act. As of 2024, specific sites such as Kaname 478 (259.83 square meters, fluorine concentration of 5.5 mg/L) and Yoshino 105-1 (158.09 square meters, hexavalent chromium concentration of 8.2 mg/L) have been designated, and remediation efforts are ongoing. Shimizu Corporation's on-site plant can now process up to 100 tons of contaminated soil per day, and DOWA Eco-System has successfully reduced the cost of hexavalent chromium remediation to 20000 yen per ton using iron powder reduction technology. Citywide, approximately 6000 tons of contaminated soil are generated annually, with an estimated annual remediation cost of 1.8 billion yen. Matsumoto City plans to utilize 50% of the remediated land for new facility construction by 2025, contributing significantly to reducing heal
th risks for residents and utilizing tourism resources. The Matsumoto City Environmental Energy Division, in collaboration with the local company Environmental Science Co., Ltd., aims to further improve efficiency and reduce costs through the adoption of advanced technologies.

Overseas Expansion of Desulfurization Equipment - Development from 1998 to the 2020s In 1998, Mitsubishi Heavy Industries and Hitachi, leading Japanese companies, began exporting desulfurization equipment to the Asian market. Demand grew particularly strong in Taiwan and South Korea, with plans to install 200 units in Taiwan and 150 units in South Korea by 2025. These units efficiently remove sulfur oxides (SOx) generated by power plants and steel mills, contributing to regional air pollution control. Employing wet scrubbing technology, they chemically absorb SOx using limestone as an absorbent. The resulting byproduct, approximately 100,000 tons of gypsum annually, is reused as construction material, helping reduce industrial waste.
Furthermore, Mitsubishi Heavy Industries formed a technical partnership with Taiwan Power Company (Taipower) to adapt to local environmental standards. In South Korea, Korea Southeast Power adopted units capable of removing over 95% of SOx. This was expected to reduce SOx emissions in South Korea by approximately 150,000 tons annually. With an eye on entering the European market, technological improvements were also advanced to meet regional environmental standards.
Entering the 2020s, Japanese companies further intensified the overseas expansion of desulfurization equipment. Mitsubishi Power, a subsidiary of Mitsubishi Heavy Industries, secured an order for two of the world's largest flue gas desulfurization (FGD) units for Serbia's Nikola Tesla B coal-fired power plant, with operation scheduled to commence in 2024. This power plant has an output of 1.34 million kW, and each FGD unit installed can process flue gas up to 670,000 kW. The introduction of these FGDs is expected to reduce SO₂ emissions by 96%, achieving levels below 130 mg/Nm³, compliant with the EU's new Industrial Emissions Directive (IED) standards.
Mitsubishi Power has delivered over 300 FGD units globally. In 2019, it secured the top market share of 37.2% in the FGD market. Cumulatively over the six years from 2014, it achieved a 37% share with a total capacity of 51.01 million kW. In the Asian market, amid rising demand for Air Quality Control Systems (AQCS) in emerging economies like China and India, Mitsubishi Power contributes to regional environmental improvement through technology transfer and guidance.
In this way, Japanese companies continue to play a vital role in improving the global environment and realizing a sustainable society by leveraging desulfurization technology.

脱硫装置の海外展開 - 1998年から2020年代までの発展
脱硫装置の海外展開 - 1998年から2020年代までの発展
1998年、日本企業の代表である三菱重工業と日立製作所は、アジア市場に向けた脱硫装置の輸出を開始しました。特に台湾と韓国での需要が高まり、2025年までに台湾で200基、韓国で150基の設置が計画されました。この装置は、発電所や製鉄工場で発生する硫黄酸化物（SOx）を効率的に除去するためのもので、地域の大気汚染の抑制に寄与しています。湿式脱硫法を採用し、石灰石を吸収剤としてSOxを化学的に吸収し、年間約10万トンの石膏として副生成物を建築資材に再利用するなど、産業廃棄物の削減にも貢献しています。
また、三菱重工業は現地の環境基準に適応するため、台湾の電力会社台電との技術提携も行い、韓国では韓国南東発電がSOxを95%以上除去する能力を持つ装置を採用。これにより韓国では年間約15万トンのSOx削減が見込まれました。さらにヨーロッパ市場への進出も視野に入れ、地域ごとの環境基準に対応するための技術改良が進められました。
2020年代に入ると、日本企業はさらに脱硫装置の海外展開を強化します。三菱重工業の子会社である三菱パワーは、セルビアのニコラ・テスラB石炭火力発電所に世界最大級の排煙脱硫装置（FGD）2基を受注し、2024年中の運転開始を予定しています。この発電所は出力134万kWで、導入されるFGDは1基あたり67万kWの排煙処理が可能です。このFGDの導入により、SO₂排出量が96%削減され、EUの新産業排出指令（IED）基準に適合する130mg/Nm³以下が達成される予定です。
三菱パワーは世界市場で300基以上のFGDの納入実績を持ち、2019年にはFGD市場でトップシェア37.2%を獲得、2014年から6年間の累計でも出力5101万kWでシェア37%を達成しています。アジア市場においても、中国やインドの新興経済圏で空気質制御システム（AQCS）の需要が高まる中、技術供与や指導を通じて地域の環境改善に貢献しています。
このように、日本企業は脱硫装置の技術を活用して、地球環境の改善と持続可能な社会の実現に向けて重要な役割を果たし続けています。

2020年代に入ると、日本企業はさらに脱硫装置の海外展開を強化します。三菱重工業の子会社である三菱パワーは、セルビアのニコラ・テスラB石炭火力発電所に世界最大級の排煙脱硫装置（FGD）2基を受注し、2024年中の運転開始を予定しています。この発電所は出力134万kWで、導入されるFGDは1基あたり67万kWの排煙処理が可能です。このFGDの導入により、SO₂排出量が96%削減され、EUの新産業排出指令（IED）基準に適合する130mg/Nm³以下が達成される予定です。
三菱パワーは世界市場で300基以上のFGDの納入実績を持ち、2019年にはFGD市場でトップシェア37.2%を獲得、2014年から6年間の累計でも出力5101万kWでシェア37%を達成しています。アジア市場においても、中国やインドの新興経済圏で空気質制御システム（AQCS）の需要が高まる中、技術供与や指導を通じて地域の環境改善に貢献しています。
このように、日本企業は脱硫装置の技術を活用して、地球環境の改善と持続可能な社会の実現に向けて重要な役割を果たし続けています。

The Journey of Satoyama Conservation and Regional Revitalization - Hisaya District, Matsuyama City The "Satoyama Conservation Project" in Hisaya District, Matsuyama City, Ehime Prefecture, launched in 2001, involves local company "Matsuyama Environmental Development" and residents working together to restore degraded forests and revitalize the community. By the 2020s, the project had achieved cumulative planting of over 200,000 trees, with forest regeneration progressing across more than 100 hectares. Improvements in the water quality of the Ishite River and the return of fireflies were observed. However, challenges remain, including landslides due to climate change, an increase in invasive species, and a shortage of workers due to an aging population. Efforts to address these issues through the use of AI technology and funds have made the project a notable model for sustainable community development.

Progress in Regulating Hazardous Waste Dumping in the North Sea - 2020s At the 1995 North Sea Protection Conference, an agreement was reached to ban hazardous waste dumping in the North Sea by 2020. By the 2020s, a significant reduction in waste had been achieved. Dumping of harmful substances, particularly lead, mercury, cadmium, and PCBs, was reduced to near zero. Germany, France, and Norway invested heavily in recycling facilities and technological development, leading to improved water quality in the North Sea. The United Kingdom has also introduced policies in recent years aiming for a complete cessation of waste dumping, continuing international cooperation for environmental protection.

The Current State of Vehicle Scrapping and Recycling in Japan Japan has recorded a vehicle ownership of 70 million units, with 5 million vehicles scrapped annually. Currently, the shredder dust remaining after dismantling these scrapped vehicles amounts to 1 million tons. As waste disposal associated with scrapped vehicles becomes increasingly serious, attention is turning not only to recycling (recycling into new resources) of car parts but also to reuse.
The Current State of Vehicle Scrapping and Recycling in Japan Japan has recorded a vehicle ownership of 70 million units, with 5 million vehicles scrapped annually. Currently, the shredder dust remaining after dismantling these scrapped vehicles amounts to 1 million tons. As waste disposal associated with scrapped vehicles becomes increasingly serious, attention is turning not only to recycling (recycling into new resources) of car parts but also to reuse.
"Current Status of Used Parts Reuse" However, in Japan, the rate of reusing used parts for automotive repairs and maintenance stands at only about 3% (equivalent to 50 billion yen), compared to 15% in Europe and over 30% in the United States. "Purpose of the Research Report" This research report details the current status and future prospects of reuse—the process within the vehicle disposal chain that imposes the least environmental burden while effectively utilizing resources.
"Germany's Initiatives" In Germany, where 2.6 million vehicles are scrapped annually, design considerations for part recycling and reuse are incorporated from the production stage. Notably, Mercedes-Benz publicly discloses which parts use used components, and consumers accept this as standard practice. In Sweden, the major insurance company "Folksam Insurance" operates a specialized subsidiary, "Folksam Auto," dedicated to dismantling scrapped vehicles and selling used parts, actively promoting the reuse of automotive components.
"Finland's Initiatives" Similarly, in Finland, three companies, including VAT Damage Repair Center Insurance, jointly operate "Autovarikos," a company specializing in vehicle dismantling and used parts sales. Since Finland lacks domestic car manufacturers, repairs are directly brought to this company, resulting in an overwhelmingly high usage rate of used parts. The company also handles a large volume of dismantling work for accident-damaged and scrapped vehicles, maintaining a rich inventory of recycled parts. The current usage rate of used parts in repairs by this company is 15% per vehicle. The goal is to increase this share to 20%.
"Initiatives by Major Automakers" Next, looking at initiatives by major automakers and Japan, Mercedes-Benz, mentioned earlier, collects approximately 110,000 batteries, 50,000 bumpers, 30,000 hubcaps, and 170,000 window panes annually from about 1,300 dealerships in Germany. These are sorted by specialized companies for recycling or reuse. Starting in November 1993, Mercedes-Benz implemented the "Mercedes Recycling System," a specialized logistics system to promote the collection, recycling, and reuse of discarded parts. This system was realized through a partnership with Rents System Transport (RST). RST currently operates an experimental plant that swiftly dismantles and sorts end-of-life vehicles.
"Volvo's Initiatives" Volvo Car Corporation (Sweden) has operated a pilot plant for reuse since 1994. By 1998, it had dismantled 3,000 passenger cars, sorting reusable parts while developing technologies for more effective reuse.
"BMW Japan's Initiatives" As part of the Japanese subsidiary of the German automaker, BMW Japan (Chiba City: 043-297-7075) began offering free end-of-life vehicle collection in 1994. Vehicles collected through dealers are transported to the Himeji plant of a partner company, where they are dismantled and sorted. Materials and parts suitable for reuse or recycling are then sold. Although the initiative currently handles only about 100 vehicles annually, the company's high recycling rate of 80-85% for its various models is cited as a factor enabling the free service. "Mercedes-Benz Japan's Initiatives" Mercedes-Benz Japan (Minato-ku) has built a system since 1980 in Japan to collect high-value parts like transmissions, engines, and gearboxes from authorized domestic dealers for reuse.
"NGP Activities" The activities of the NGP (Nippon Good Parts) Group are also significant. The group currently has 107 member companies, a total of 117 distribution hubs, and possesses an inventory of 350,000 items. Its total annual sales reach 18 billion yen, making it Japan's largest "recycled parts distribution group" and playing a major role in the automotive repair market. One key feature of the group is the utilization of the online "Super Line" system accessible to all members. While individual member companies might hold only a few thousand items each, consolidating all member inventories online enables the group to instantly access a shared inventory of 350,000 items. Locating any single item within this inventory takes just 30 seconds. Computer access to the system reaches 200,000 hits per month, with over 60,000 items traded online monthly on average.
"Japanese Manufacturers' Response" In contrast, Japanese manufacturers show little engagement with reuse. Companies like Toyota Motor Corporation, Honda Motor Co., Ltd., Fuji Heavy Industries Ltd., and Isuzu Motors Ltd. are involved in initiatives such as bumper collection and recycling. However, only two manufacturers—Toyota and Honda—currently operate nationwide programs. Even then, these programs focus solely on used bumpers generated by their respective dealer networks.
"Japan's Reuse Market" Consequently, the current Japanese auto parts reuse market is supported by used car dealers (approx. 50,000 stores), auto dismantlers (approx. 5,000 companies), auto repair shops (approx. 60,000 companies), and used parts retailers (approx. 300 companies). Among these, Shimizu Shokai (Kumagaya City: 0485-24-0610) stands out as a rapidly growing pioneer in used auto parts sales, having completely transitioned from being an auto dismantler. "Shimizu Shokai's Initiatives" Shimizu Shokai thoroughly leveraged such support systems, achieving approximately 60 employees and annual sales of ¥1.05 billion in fiscal 1995. Furthermore, sales of ¥1.4 billion are projected for fiscal 1996. The company sells parts directly usable from scrapped vehicles to approximately 10,000 auto repair shops nationwide. Processing around 150 scrapped vehicles monthly, the company currently holds inventory of about 50,000 parts, claiming to stock nearly all parts for vehicles over
five years old.
"Prospects for the Reuse Market" "Reusing and recycling car parts is commonplace in Europe and America. Conditions are gradually improving in Japan too. I believe this market will reach around ¥300 billion in the near future," stated President Nobuo Shimizu. While part reuse in Japan is currently limited to repairing used cars, if it becomes as common as in Europe and America for new cars, the market will likely expand further.
"Reintroducing the NGP Group" Additionally, the activities of the NGP (Nippon Good Parts) Group, established in 1986 as a consortium of industry peers supporting the company's current business operations, are significant. The group currently has 107 member companies, a total of 117 distribution hubs, and possesses an inventory of 350,000 items. Its total annual sales reach ¥18 billion, making it Japan's largest "recycled parts distribution group" and playing a major role in the automotive repair market. One key feature of the group is the use of the online "Super Line" system accessible to all members. While individual member companies might hold only a few thousand items each, consolidating all member inventories online enables the group to instantly access a shared inventory of 350,000 items. Finding a single item from this inventory takes just 30 seconds. Computer access to the system reaches 200,000 times per month. The number of items traded online averages over 60,000
per month.

「日本における廃車とリサイクルの現状」日本では7000万台もの保有台数を記録し、年間で500万台が廃車となっている。現在、その廃車の解体作業の中で最後に残るシュレッダーダストは100万トンにも及ぶ。こうした廃車に伴う廃棄物処理が深刻化する中で、車部品のリサイクル（再資源化）のほか、リユース（再利用）が注目され始めている。
「日本における廃車とリサイクルの現状」日本では7000万台もの保有台数を記録し、年間で500万台が廃車となっている。現在、その廃車の解体作業の中で最後に残るシュレッダーダストは100万トンにも及ぶ。こうした廃車に伴う廃棄物処理が深刻化する中で、車部品のリサイクル（再資源化）のほか、リユース（再利用）が注目され始めている。
「中古部品再利用の現状」しかし、日本では、自動車の補修などに中古部品を再利用する比率は、ヨーロッパで15%、米国では30%以上と比べると、まだ3%（金額にして500億円）程度というのが現状である。
「調査レポートの目的」今回の調査レポートでは廃車処理の一連の過程において最も環境に負荷が少なく、かつ資源を有効に活用するリユースについての現状と展望を報告する。
「ドイツの取り組み」ドイツでは、年間260万台の自動車が廃車となっている現状において、生産段階から部品のリサイクルやリユースに考慮した設計がなされている。中でも、メルセデス・ベンツ社では中古部品が使われている部分を公表し、消費者側もそれを当然のこととして受けとめているという。また、スウェーデンでは、大手損害保険会社「フォルクサム保険会社」が廃車の解体や中古部品の販売を行なう専門子会社「フォルクサムオート」を持ち、積極的な自動車部品のリユースを展開している。
「フィンランドの取り組み」さらにフィンランドでも同様に、VAT損傷車補修センター保険会社をはじめとする3社が共同で、廃車解体・中古部品販売会社「アウトバヒンコキスコス」を経営している。同国はカーメーカーを自国に持たないことから、同社に修理などが直接持ち込まれるため、中古部品の使用比率が圧倒的に高い。同社は事故車・廃車の解体作業も多く、リサイクルパーツの在庫も豊富だ。同社の補修による中古部品の使用率は現在、車1台につき15％だ。これを20％までのシェア向上を目標としている。
「代表的な自動車会社の取り組み」次に、代表的な自動車会社およびわが国の取り組みについて見ると、前出のメルセデス・ベンツ社では、ドイツ国内の販売店約1300カ所で、年間にバッテリー11万個、バンパー5万本、ハブキャップ3万個、窓ガラス17万枚を回収し、それぞれの専門業者により、そのリサイクルかリユースに分別されている。93年11月から、廃棄された部品の回収とリサイクル、リユース促進のための特別な物流システム「メルセデス・リサイクリング・システム」を実施した。このシステムはレンツ・システム・トランスポート社(RST)との提携によって実現したもの。RSTでは現在、廃車の解体と分別をすみやかに行なう実験プラントを稼働している。
「ボルボの取り組み」ボルボ・カー・コーポレーション（スウェーデン）では、94年からリユースのためのパイロットプラントを操業している。98年までに3000台の乗用車を解体し、リユース可能な部品の分類作業を行なうとともに、より効果的なリユースのための技術開発に取り組んでいる。
「BMWジャパンの取り組み」ドイツ自動車会社の日本現地法人の取り組みとして、BMWジャパン（千葉市：043-297-7075)では、94年より廃車の無料引き取りをはじめた。ディーラー経由で回収した廃車は提携業者の姫路工場に運ばれ、解体・仕分けし、リユースやリサイクルできる素材や部品は販売している。まだ、年間100台程度の取り組みだが、80-85％に達する同社各車種の高いリサイクル率が無料を可能にした一因だという。
「メルセデス・ベンツ日本の取り組み」メルセデス・ベンツ日本（港区では、日本において80年から、トランスミッション、エンジン、ギアボックスなどの高価値部品を国内の正規ディーラーから回収し、リユースするシステムを構築している。
「NGPの活動」NGP（日本グッド・パーツ）グループの活動も重要だ。同グループでは、現在加盟会員企業数107社、流通拠点延べ総数は117拠点、商品在庫点数に至っては35万点を所有している。年間総売り上げ高は全体で180億円にも達し、わが国最大の「リサイクル部品流通企業集団」として、自動車補修市場活動に大きな役割を果たしている。同グループの特徴の一つとして、グループ会員全てにオンライン化した「スーパーライン」の活用がある。これは一会員企業だけでは数千点ずつだが、会員全社の在庫をオンライン化することによって、一気にグループの共有在庫35万点を可能とした。35万点の中から1点を選び出す時間はわずか30秒。コンピューターでのアクセスは月間20万回にも上る。オンラインで取引される商品数は月間平均6
万点強だという。
「日本のメーカーの対応」その一方、日本のメーカーのリユースへの対応はほとんどない。トヨタ自動車、本田技研工業、富士重工業、いすゞ自動車などが、バンパーの回収・リサイクルなどに取り組んでいる。しかし、全国規模で実施しているメーカーは、今のところトヨタと本田の2社だけだ。それも、それぞれの系列ディーラーで発生する使用済みバンパーが対象となっている。
「日本のリユース市場」こうしたことから、現在日本の自動車部品のリユースを支えているのは、中古車販売店（約5万店）、自動車解体業者（約5000社）、自動車修理業者（約6万社）、中古部品販売業者（約300社）などだ。その中で急成長しているのが、自動車解体業者から完全転換し、自動車中古部品販売のパイオニア的存在となった清水商会（熊谷市：0485-24-0610) だ。
「清水商会の取り組み」清水商会ではこのようなサポートシステムも徹底活用し、95年度には従業員約60名、年商10億5000万円を計上した。さらに96年度には14億円の売上げが予想されている。同社では、廃車の中からそのまま使用できる部品を全国約1万の自動車修理工場向けに販売している。月に150台前後の廃車を処理し、現在同社が持つ在庫部品点数は約5万点、5年以上前の車のパーツならほとんどのものが揃うという。
「リユース市場の展望」「車の部品のリユースおよびリサイクルは欧米では当たり前。日本でもだんだん条件が整ってきた。近い将来は3000億円ほどの市場になると思います」 （清水信夫社長）という。日本では部品のリユースは中古車の補修に限定されているが、欧米なみに新車にも使用されたりすると、その市場はさらに拡大するだろう。
「NGPグループの再紹介」また、今日の同社の事業経営を支える同業者企業集団として、86年に創設されたNGP（日本グッド・パーツ）グループの活動も重要だ。同グループでは、現在加盟会員企業数107社、流通拠点延べ総数は117拠点、商品在庫点数に至っては35万点を所有している。年間総売り上げ高は全体で180億円にも達し、わが国最大の「リサイクル部品流通企業集団」として、自動車補修市場活動に大きな役割を果たしている。同グループの特徴の一つとして、グループ会員全てにオンライン化した「スーパーライン」の活用がある。これは一会員企業だけでは数千点ずつだが、会員全社の在庫をオンライン化することによって、一気にグループの共有在庫35万点を可能とした。35万点の中から1点を選び出す時間はわずか30秒。コン�

「フィンランドの取り組み」さらにフィンランドでも同様に、VAT損傷車補修センター保険会社をはじめとする3社が共同で、廃車解体・中古部品販売会社「アウトバヒンコキスコス」を経営している。同国はカーメーカーを自国に持たないことから、同社に修理などが直接持ち込まれるため、中古部品の使用比率が圧倒的に高い。同社は事故車・廃車の解体作業も多く、リサイクルパーツの在庫も豊富だ。同社の補修による中古部品の使用率は現在、車1台につき15％だ。これを20％までのシェア向上を目標としている。
「代表的な自動車会社の取り組み」次に、代表的な自動車会社およびわが国の取り組みについて見ると、前出のメルセデス・ベンツ社では、ドイツ国内の販売店約1300カ所で、年間にバッテリー11万個、バンパー5万本、ハブキャップ3万個、窓ガラス17万枚を回収し、それぞれの専門業者により、そのリサイクルかリユースに分別されている。93年11月から、廃棄された部品の回収とリサイクル、リユース促進のための特別な物流システム「メルセデス・リサイクリング・システム」を実施した。このシステムはレンツ・システム・トランスポート社(RST)との提携によって実現したもの。RSTでは現在、廃車の解体と分別をすみやかに行なう実験プラントを稼働している。
「ボルボの取り組み」ボルボ・カー・コーポレーション（スウェーデン）では、94年からリユースのためのパイロットプラントを操業している。98年までに3000台の乗用車を解体し、リユース可能な部品の分類作業を行なうとともに、より効果的なリユースのための技術開発に取り組んでいる。
「BMWジャパンの取り組み」ドイツ自動車会社の日本現地法人の取り組みとして、BMWジャパン（千葉市：043-297-7075)では、94年より廃車の無料引き取りをはじめた。ディーラー経由で回収した廃車は提携業者の姫路工場に運ばれ、解体・仕分けし、リユースやリサイクルできる素材や部品は販売している。まだ、年間100台程度の取り組みだが、80-85％に達する同社各車種の高いリサイクル率が無料を可能にした一因だという。
「メルセデス・ベンツ日本の取り組み」メルセデス・ベンツ日本（港区では、日本において80年から、トランスミッション、エンジン、ギアボックスなどの高価値部品を国内の正規ディーラーから回収し、リユースするシステムを構築している。
「NGPの活動」NGP（日本グッド・パーツ）グループの活動も重要だ。同グループでは、現在加盟会員企業数107社、流通拠点延べ総数は117拠点、商品在庫点数に至っては35万点を所有している。年間総売り上げ高は全体で180億円にも達し、わが国最大の「リサイクル部品流通企業集団」として、自動車補修市場活動に大きな役割を果たしている。同グループの特徴の一つとして、グループ会員全てにオンライン化した「スーパーライン」の活用がある。これは一会員企業だけでは数千点ずつだが、会員全社の在庫をオンライン化することによって、一気にグループの共有在庫35万点を可能とした。35万点の中から1点を選び出す時間はわずか30秒。コンピューターでのアクセスは月間20万回にも上る。オンラインで取引される商品数は月間平均6
万点強だという。
「日本のメーカーの対応」その一方、日本のメーカーのリユースへの対応はほとんどない。トヨタ自動車、本田技研工業、富士重工業、いすゞ自動車などが、バンパーの回収・リサイクルなどに取り組んでいる。しかし、全国規模で実施しているメーカーは、今のところトヨタと本田の2社だけだ。それも、それぞれの系列ディーラーで発生する使用済みバンパーが対象となっている。
「日本のリユース市場」こうしたことから、現在日本の自動車部品のリユースを支えているのは、中古車販売店（約5万店）、自動車解体業者（約5000社）、自動車修理業者（約6万社）、中古部品販売業者（約300社）などだ。その中で急成長しているのが、自動車解体業者から完全転換し、自動車中古部品販売のパイオニア的存在となった清水商会（熊谷市：0485-24-0610) だ。
「清水商会の取り組み」清水商会ではこのようなサポートシステムも徹底活用し、95年度には従業員約60名、年商10億5000万円を計上した。さらに96年度には14億円の売上げが予想されている。同社では、廃車の中からそのまま使用できる部品を全国約1万の自動車修理工場向けに販売している。月に150台前後の廃車を処理し、現在同社が持つ在庫部品点数は約5万点、5年以上前の車のパーツならほとんどのものが揃うという。
「リユース市場の展望」「車の部品のリユースおよびリサイクルは欧米では当たり前。日本でもだんだん条件が整ってきた。近い将来は3000億円ほどの市場になると思います」 （清水信夫社長）という。日本では部品のリユースは中古車の補修に限定されているが、欧米なみに新車にも使用されたりすると、その市場はさらに拡大するだろう。
「NGPグループの再紹介」また、今日の同社の事業経営を支える同業者企業集団として、86年に創設されたNGP（日本グッド・パーツ）グループの活動も重要だ。同グループでは、現在加盟会員企業数107社、流通拠点延べ総数は117拠点、商品在庫点数に至っては35万点を所有している。年間総売り上げ高は全体で180億円にも達し、わが国最大の「リサイクル部品流通企業集団」として、自動車補修市場活動に大きな役割を果たしている。同グループの特徴の一つとして、グループ会員全てにオンライン化した「スーパーライン」の活用がある。これは一会員企業だけでは数千点ずつだが、会員全社の在庫をオンライン化することによって、一気にグループの共有在庫35万点を可能とした。35万点の中から1点を選び出す時間はわずか30秒。コン�

Environmental Damage from Urban Flooding (1990s–2020s) - May 1996 1990s: Urban flooding caused by torrential downpours became frequent in the 1990s, posing challenges nationwide in Japan. The summer of 1994 saw severe water shortages, prompting increased attention to rainwater reuse. In Tokyo, the Sumida Ward Office introduced a 1,000-cubic-meter underground rainwater storage tank, reusing over 30,000 tons of water annually. Additionally, the Tokyo Dome (designed by Takenaka Corporation) collected rainwater from its 36,000-square-meter roof, using 600 cubic meters per day for toilet flushing.
Environmental Damage from Urban Flooding (1990s–2020s) - May 1996 1990s: Urban flooding caused by torrential downpours became frequent in the 1990s, posing challenges nationwide in Japan. The summer of 1994 saw severe water shortages, prompting increased attention to rainwater reuse. In Tokyo, the Sumida Ward Office introduced a 1,000-cubic-meter underground rainwater storage tank, reusing over 30,000 tons of water annually. Additionally, the Tokyo Dome (designed by Takenaka Corporation) collected rainwater from its 36,000-square-meter roof, using 600 cubic meters per day for toilet flushing.
In Fukuoka City, Fukuoka Dome installed a 2,900-cubic-meter rainwater storage tank, utilizing approximately 55,000 cubic meters of rainwater annually for plant irrigation and toilet flushing. These initiatives aimed to balance preventing urban flooding with efficient resource use, though collaboration between local residents and businesses remained a challenge.
2000s: In 2001, Tokyo completed the "Metropolitan Outer Ring Floodway" (Underground Temple), consisting of a 6.3-kilometer tunnel and a massive pressure-regulating reservoir, capable of draining over 500,000 cubic meters of rainwater annually. This facility prevented flooding in approximately 20,000 households during the heavy rains of 2008, achieving significant results.
Osaka City formulated its "Basic Plan for Heavy Rain Countermeasures in Sewers" in 2004, developing drainage capacity to handle rainfall of 70 mm per hour. In 2009, it expanded rainwater storage facilities in the Yodo River basin, increasing total storage capacity to 50,000 cubic meters. Furthermore, collaboration with businesses and research institutions advanced flood prediction technology, contributing to disaster risk reduction.
2010s: Amid frequent extreme weather due to climate change, Tokyo promoted the "Tama River Flood Countermeasure Project." During Typhoon No. 15 in 2011, enhanced drainage pumps minimized damage in the Arakawa River basin. Furthermore, during the 2014 flash floods, Sumida Ward's underground storage basin activated, processing approximately 12,000 cubic meters of rainwater.
In Osaka City, the "Osaka Mega Rainwater Storage System," designed by Takenaka Corporation, began operation in 2015. With a storage capacity of approximately 100,000 cubic meters, it streamlined drainage into Osaka Bay. In Fukuoka City, the storage capacity of the Sannō Retention Pond doubled in 2018, enabling the reuse of 70,000 cubic meters of rainwater annually. This significantly mitigated damage during Typhoon No. 21.
2020s: Since 2020, Tokyo has advanced expansion work on the Metropolitan Outer Floodway. In 2023, new drainage pumps were introduced. Capable of discharging 45 tons of rainwater per minute, these pumps further reduced flood risks for residential areas along the Arakawa River.
Osaka City promoted its "Osaka Mega-Flood Countermeasures" in 2022, increasing the total capacity of its storage tanks to 100 million cubic meters. Furthermore, in collaboration with Daikin Industries, it introduced new rainwater filtration systems. The purified rainwater is now also utilized for urban greening projects.
In Fukuoka City, the "Smart Rainwater Storage System," developed with Daikin's cooperation, was introduced in 2023, achieving an annual reusable rainwater volume of 120,000 cubic meters. This has significantly mitigated flood damage during typhoons and reduced disaster risk.

都市型洪水による環境被害（1990年代～2020年代）-1996年5月
都市型洪水による環境被害（1990年代～2020年代）-1996年5月
1990年代：
集中豪雨による都市型洪水は1990年代に入ってから頻発し、日本全国で課題となりました。1994年の夏には深刻な水不足があり、雨水の再利用が注目され始めました。東京では墨田区庁舎が地下1000立方メートルの雨水貯留タンクを導入し、年間3万トン以上の水を再利用していました。また、東京ドーム（竹中工務店設計）では3万6000平方メートルの屋根から雨水を集水し、1日600立方メートルをトイレ洗浄水として利用していました。
福岡市では福岡ドームが2900立方メートルの雨水貯留タンクを導入し、年間約5.5万立方メートルの雨水を植栽散水や便器洗浄に活用しました。こうした取り組みは、都市型洪水の防止と資源の有効活用の両立を目指して実施されましたが、地域住民や企業間での連携が課題として残されました。
2000年代：
2001年、東京都が完成させた「首都圏外郭放水路」（地下神殿）は、全長6.3kmのトンネルと巨大な調圧水槽から成り、年間50万立方メートル以上の雨水を排水可能としました。この施設は、2008年の豪雨時に約2万世帯の浸水を防ぎ、大きな成果を上げました。
大阪市では、2004年に「下水道豪雨対策基本計画」を策定し、1時間あたり70mmの降雨に対応する排水能力を整備。2009年には淀川流域に雨水貯留施設を増設し、合計貯留能力を5万立方メートルまで拡張しました。さらに、企業や研究機関との連携で洪水予測技術が進化し、災害リスクの軽減に貢献しました。
2010年代：
気候変動の影響で異常気象が頻発する中、東京都は「多摩川浸水対策プロジェクト」を推進。2011年の台風15号では、排水ポンプの強化により荒川流域の被害を最小限に抑えました。また、2014年のゲリラ豪雨では、墨田区の地下調整池が稼働し、約1.2万立方メートルの雨水を処理しました。
大阪市では2015年、竹中工務店が設計した「大阪メガ雨水貯留システム」が稼働を開始。約10万立方メートルの貯水能力を持ち、大阪湾への排水を効率化しました。福岡市では2018年、山王調整池の貯留能力が倍増し、年間7万立方メートルの雨水を再利用。これにより、台風21号時の被害を大幅に軽減しました。
2020年代：
2020年以降、東京都では首都圏外郭放水路の拡張工事が進められ、2023年には新型排水ポンプが導入されました。このポンプは1分間で45トンの雨水を排水でき、荒川沿いの住宅地の洪水リスクをさらに低減させました。
大阪市は2022年に「大阪メガフラッド対策」を推進し、貯留タンクの総容量を1億立方メートルに増強。さらに、ダイキン工業と連携し、新型雨水ろ過装置を導入。これにより浄化された雨水は都市緑化事業にも活用されています。
福岡市では2023年、ダイキンの協力で開発された「スマート雨水貯留システム」が導入され、再利用可能な雨水量が年間12万立方メートルに達しました。これにより、台風時の洪水被害が大幅に軽減され、災害リスクが低下しています。

Food Bank Development - Status in the 2020s (October 2020) In the 2020s, as concerns over environmental pollution and food safety increased, the role of Japan's food bank became even more critical. In particular, the accumulation of heavy metals and dioxins in food products due to environmental pollution has become a major issue, and monitoring systems across the country have been strengthened.
Food Bank Development - Status in the 2020s (October 2020) In the 2020s, as concerns over environmental pollution and food safety increased, the role of Japan's food bank became even more critical. In particular, the accumulation of heavy metals and dioxins in food products due to environmental pollution has become a major issue, and monitoring systems across the country have been strengthened.
For example, in Fukushima Prefecture, after the 2011 nuclear disaster, the influence of radioactive cesium-137 remains, and strict safety inspections of agricultural and marine products are ongoing. Only products that meet strict standards based on radiation tests are allowed to be distributed in the market.
Additionally, in Ise Bay, Mie Prefecture, mercury and cadmium pollution from industrial wastewater is a serious concern, and monitoring of marine products continues. The national food bank network collaborates to freeze food samples and conduct regular analyses.
Companies such as Nichirei, known for their freezing technology, and Marubeni, a general trading company, actively contribute to this initiative by providing cutting-edge freezing equipment. Nichirei, in particular, has introduced ultra-low temperature freezing technology at -60°C, ensuring long-term food preservation. This technology enhances efforts to reduce food waste while ensuring food safety.
Moreover, the government and corporations have implemented blockchain technology to manage food bank data, improving traceability and ensuring swift detection and response to food affected by contaminants. In 2020, approximately 1.5 million tons of food were managed through the food bank, contributing to food safety and the establishment of a sustainable food system.

"Toward a Lake Kasumigaura Where You Can Swim" - The Challenge from 2007 to the 2020s In 2007, Ibaraki Prefecture announced a plan to improve Lake Kasumigaura's water quality, adopting "Toward a Lake Kasumigaura Where You Can Swim" as its theme in the Environmental White Paper. At that time, Lake Kasumigaura was suffering from advanced eutrophication, and blue-green algae blooms were severely impacting the lake's ecosystem and local residents. With five lakes in the prefecture failing to meet environmental standards, improving Lake Kasumigaura was positioned as an urgent priority. Ibaraki Prefecture strengthened discharge regulations, improved water circulation, and advanced proper management of domestic and agricultural wastewater, fostering collaboration with local residents and businesses. The "Lake Kasumigaura Basin Comprehensive Water Quality Improvement Project" is ongoing into the 2020s. Although sewage treatment coverage has reached over 90%, the inflow of untreated w
astewater remains a challenge. The introduction of environmentally conscious pesticides developed by Sumitomo Chemical Co., Ltd. and new river monitoring technologies is advancing. Furthermore, the Ministry of the Environment and Ibaraki Prefecture are considering further regulatory tightening to address nitrite nitrogen concentrations exceeding environmental standards in the Kita-Ura Basin.
Improving Lake Kasumigaura directly impacts the health and economic development of the local community, and efforts to realize a "Lake Kasumigaura where you can swim" continue. --- Related Information Sources 1.

「泳げる霞ヶ浦を目指して」-2007年から2020年代までの挑戦
「泳げる霞ヶ浦を目指して」-2007年から2020年代までの挑戦
茨城県は2007年に環境白書で「泳げる霞ヶ浦を目指して」をテーマに掲げ、霞ヶ浦の水質改善に取り組む計画を発表しました。当時の霞ヶ浦は富栄養化が進行し、アオコの発生が湖の生態系と地域住民に深刻な影響を与えていました。環境基準を満たせない湖沼が県内に5カ所存在し、霞ヶ浦の改善は緊急の課題として位置付けられました。茨城県は排水規制の強化、水循環の改善、生活排水や農業排水の適切な管理を進め、地域住民や企業との連携を図りました。
2020年代には「霞ヶ浦流域総合水質改善プロジェクト」が進行中です。下水処理普及率は90％以上に達したものの、未処理排水の流入が課題として残っています。住友化学株式会社が開発した環境配慮型農薬や、新たな河川モニタリング技術の導入が進められています。また、環境省や茨城県は北浦流域の亜硝酸性窒素濃度の環境基準超過に対応するため、さらなる規制強化を検討しています。
霞ヶ浦の改善は地域社会の健康と経済の発展に直結しており、「泳げる霞ヶ浦」を実現するための取り組みは継続しています。

History of Satoyama Conservation Activities and Regional Revitalization - Hisaya District, Matsuyama City, Ehime Prefecture In 2001, the Hisaya Satoyama Conservation Project began in the Hisaya district of Matsuyama City, Ehime Prefecture. Its goals were to restore the deteriorating satoyama landscape and revitalize the local community. This project was developed through cooperation between the local company Matsuyama Environmental Development Co., Ltd. and residents, aiming for sustainable development.

Its goals were to restore the deteriorating satoyama landscape and revitalize the local community. This project was developed through cooperation between the local company Matsuyama Environmental Development Co., Ltd. and residents, aiming for sustainable development.
Initial activities included planting 5,000 broadleaf and coniferous trees annually and implementing the "River Guardians" program to improve the water quality of the clear-flowing Ishite River. By the early 2010s, the planted area reached 50 hectares, showing signs of ecosystem recovery, such as the return of wild boars and raccoon dogs. Furthermore, production of the local specialty "Kutani Tea" increased by 30%, and visitor numbers to the tourist farm exceeded 20,000 annually. Entering the 2020s, the initiative expanded further. The cumulative number of trees planted surpassed 200,000, and the target area expanded to over 100 hectares. Moreover, the COD (Chemical Oxygen Demand) of the Ishite River improved to 7mg/L, and the arrival of fireflies gained attention as a tourist attraction. In 2019, the number of tourists reached 35,000 annually, with 5,000 visitors participating in nature experience programs at the newly established "Kutani Ecotourism Center."
However, challenges for the 2020s have also emerged. Frequent abnormal weather events due to climate change caused 3% of the planted area to be lost to landslides. Additionally, the proliferation of the invasive species, Japanese knotweed, and a decline in volunteer numbers due to the aging local population present challenges. To address this, Matsuyama Environmental Development Co., Ltd. has introduced tree-planting support robots utilizing AI technology, initiating efforts to streamline activities across the entire region. Furthermore, the "Kutani Future Fund" has been established to strengthen the foundation of activities while soliciting donations nationwide. For over 20 years, satoyama conservation activities in the Kutani area have pursued sustainable development and achieved significant results.

里山保護活動の歴史と地域再生の歩み - 愛媛県松山市久谷地区
里山保護活動の歴史と地域再生の歩み - 愛媛県松山市久谷地区
2001年、愛媛県松山市久谷地区では、荒廃が進む里山の再生と地域活性化を目的とした「久谷里山保全プロジェクト」がスタートしました。このプロジェクトは、地元企業「松山環境開発株式会社」と地域住民が協力し、持続可能な発展を目指して展開されました。
当初の活動では、毎年5000本の広葉樹や針葉樹の植樹が行われ、清流石手川の水質改善を目指した「川の守り隊」プログラムが実施されました。2001年から2010年代初頭までに、植樹面積は50ヘクタールに達し、イノシシやタヌキなどが復活するなど、生態系の回復が見られました。さらに、地域特産品「久谷茶」の生産量が3割増加し、観光農園の来訪者数は年間2万人を超える成果を上げました。
2020年代に入ると、この活動はさらに拡大。植樹本数は累計20万本を超え、対象区域は100ヘクタール以上に拡大しました。また、石手川のCOD（化学的酸素要求量）は7mg/Lに改善され、ホタルの飛来が観光資源として注目されるようになりました。2019年の観光客数は年間35000人に達し、新設された「久谷エコツーリズムセンター」では、年間5000名の観光客が自然体験プログラムに参加しています。
一方で、2020年代の課題も顕在化しています。気候変動の影響で頻発する異常気象により、植樹地の3%が土砂崩れで失われました。また、外来種アレチウリの繁殖や地域住民の高齢化に伴うボランティア数の減少が課題となっています。これに対応するため、「松山環境開発株式会社」はAI技術を活用した植樹支援ロボットを導入し、地域全体の活動を効率化する取り組みを開始。また、「久谷未来基金」を設立し、全国から寄付金を募りながら活動基盤を強化しています。
久谷地区での里山保護活動は、20年以上にわたり持続可能な発展を追求し、多くの成果を上げてきました。2020年代は、自然保護の成功を基盤に新たな課題を克服しつつ、地域住民と企業が連携して未来を切り開く重要な局面を迎えています。

**Hachijo Island's Food Waste Recycling Initiative - History and Current Status** --- **1998: Beginning of the Recycling Project** In 1998, Hachijo Island in Tokyo began a food waste recycling initiative aimed at utilizing regional resources and reducing the burden of waste disposal. This project started as a pilot test involving 270 households in the city housing complex, establishing a system to compost approximately 300 tons of food waste annually. At the composting facility, microorganisms were used to decompose food waste, producing organic fertilizer distributed to local farmers. This compost was utilized in the cultivation of specialty products such as potatoes and tomatoes, balancing agricultural economics and environmental conservation.
The composting process employed a high-efficiency decomposition device developed by Kankyo Techno Co., Ltd., which reduced processing time and improved treatment capacity. At this stage, the goal was to process 20% of the food waste into compost, laying the foundation for a sustainable living environment. --- **2010s: Establishing a Circular Society and Collaboration with Tourism**
In the 2010s, Hachijo Island's recycling project evolved into efforts to establish a circular society across the region. In 2015, the composting facility was expanded, increasing its processing capacity to 800 tons annually. While tourism supported the island's economy, the increase in tourists presented challenges in waste management, leading to the full-scale collection of food waste from tourist facilities and restaurants.
During this period, local use of compost was further promoted, benefiting not only farmers but also school and public facility greening projects. Additionally, Hachijo Island was selected for the "Island Environment Model Project" led by the Tokyo Metropolitan Government, enhancing collaboration with municipalities and companies. The reduction of chemical fertilizer usage through composting was achieved island-wide, balancing environmental and economic benefits.
--- **2020s: Expansion and Technological Advancement**
In the 2020s, Hachijo Island's food waste recycling initiative achieved further advancements. The project expanded to cover the entire island, with an annual capacity to process approximately 1000 tons of food waste. The composting facility adopted the latest decomposition equipment developed by Kankyo Techno Co., Ltd., enabling processing times to be halved and supporting an annual capacity of 1500 tons.
The use of compost reduced chemical fertilizer usage by 25% annually, easing the financial burden on farmers. It also improved the quality of Hachijo Island's specialty products, including potatoes and tomatoes. Furthermore, food waste from tourist facilities and restaurants, accounting for an additional 200 tons annually, was newly targeted, raising the total processing volume to approximately 1200 tons per year.
This initiative, led by the Hachijo Island Town Office in collaboration with the Tokyo Metropolitan Government, has gained recognition as a model case for regional societies. Plans for expansion to neighboring Izu Islands are also being considered, spreading efforts toward a sustainable society. --- **Conclusion**
Since its inception in 1998, Hachijo Island's food waste recycling initiative has expanded in scale and advanced technologically. In the 2010s, it strengthened collaboration with the tourism sector and established the foundation for a circular society. By the 2020s, it further expanded its scope, emerging as a success story in achieving a sustainable regional society. Prospects for expansion to other areas continue to grow.

The composting facility adopted the latest decomposition equipment developed by Kankyo Techno Co., Ltd., enabling processing times to be halved and supporting an annual capacity of 1500 tons.
The use of compost reduced chemical fertilizer usage by 25% annually, easing the financial burden on farmers. It also improved the quality of Hachijo Island's specialty products, including potatoes and tomatoes. Furthermore, food waste from tourist facilities and restaurants, accounting for an additional 200 tons annually, was newly targeted, raising the total processing volume to approximately 1200 tons per year.
This initiative, led by the Hachijo Island Town Office in collaboration with the Tokyo Metropolitan Government, has gained recognition as a model case for regional societies. Plans for expansion to neighboring Izu Islands are also being considered, spreading efforts toward a sustainable society.
---
**Conclusion**
Since its inception in 1998, Hachijo Island's food waste recycling initiative has expanded in scale and advanced technologically. In the 2010s, it strengthened collaboration with the tourism sector and established the foundation for a circular society. By the 2020s, it further expanded its scope, emerging as a success story in achieving a sustainable regional society. Prospects for expansion to other areas continue to grow.

Recycle Mine Bark Project - June 1995 In 1995, the Japan Mining Association launched the "Recycle Mine Bark Project." This initiative aims to efficiently reuse discarded home appliances and industrial waste by utilizing closed mines, such as the Osarizawa Mine in Aomori Prefecture and the Kosaka Mine in Akita Prefecture, as recycling hubs. Major companies like Mitsui Mining & Smelting and Sumitomo Metal Mining participate, utilizing refining technologies to recover precious metals such as copper, aluminum, iron, and gold from thousands of tons of waste annually. For example, approximately 20,000 tons of copper and 10,000 tons of aluminum are recovered and recycled annually from refrigerators and televisions. Furthermore, in cooperation with the Ministry of the Environment, waste collection is being advanced nationwide, with hundreds of thousands of tons of industrial waste being reused annually across Japan. This initiative is gaining attention both domestically and internati

In the 2000s, the import of electronic waste (E-waste) from Southeast Asian countries increased. DOWA Group's Kosaka Smelting and Mitsubishi Materials' Naoshima Smelter played key roles in recycling waste containing lead, copper, and silver. By 2005, the import volume reached 14637 tons, highlighting the importance of waste management, though illegal transport remained a significant challenge.
#### 2010s: Amendment of the Basel Law and Simplification of Import Procedures
In 2018, Japan amended its Basel Law, introducing a pre-consent mechanism to expedite the import of waste to environmentally conscious recycling facilities. As a result, the import of items like printed circuit boards (PCBs) and used batteries became smoother, and the number of regulated items was reduced. Companies such as Mitsubishi Materials and JX Metals expanded their capacity to handle hazardous waste containing lead and mercury.
#### 2020s: Strengthening Monitoring and International Cooperation against Illegal Transport In the 2020s, Japan enhanced cooperation with Southeast Asian countries and strengthened its monitoring system against illegal transport. In 2020, 72112 tons of hazardous waste were imported, with much of it processed at facilities like Mitsubishi Materials' Naoshima Smelter and JX Metals' Hitachi Smelter. Additionally, issues such as fires and odors from improper electronic waste management have arisen, prompting the government to increase enforcement efforts. Through these efforts, Japan aims to balance efficient waste management with environmental conservation, complying with the Basel Convention and advancing technologies that contribute to global environmental protection.
