California Renewable Energy full transition 2018.12

<California is a unique renewable energy policy.>

In response to the Trump regime, which proved to be withdrawn from the "Paris Agreement", the international Framework for global warming countermeasures, California will promote its own state-level global warming strategy. As a medium-term target, we will raise the power generation ratio by renewable energy such as wind, solar, hydro, etc. to electricity companies in the state to 60% by the end of 30%.

Government buildings and other state-related facilities switch to renewable energy in the year of target achievement It is said that it is It will be implemented from January next year. In the United States, the difference between the central government and the local government is clear about environmental policy.

ESCO and the resource company business 1999.05.15

In the Environmental business field, energy conservation and resource-related business are likely to stand up. In the energy saving business, various technologies, products, and services related to energy saving and power saving are born to promote the rationalization of the use of energies. In Europe and the United States, it is called the Energy Service Company (ESCO) business, and it is in full swing as a business to provide the facilities, technology, manpower, and funds to enable energy saving and power saving for existing construction and factories.

In the Japan, it is commercialized for the enterprise, and energy saving and the power saving equipment are becoming popular gradually in the general process. The resource Service company business related to the resource saving if you want there is a business that such a ESCO business leads to energy saving, and it is not amusing to be commercialized in earnest. It is a support business that re-emphasizes production-oriented social structures and is a "resource saving" type. For each company and local government, we have developed a small amount of high-value-added products, the development of recycled resource-based product, the resource procurement of products, and the consulting of Life Cycle Assessment (LCA) for all production, distribution, consumption and disposal. It can be said that this is a comprehensive project to promote resource saving such as introduction of recycling technology and clustering of wastes.

This business is in full swing to promote resource saving and recycling technology. Japan imports vast amounts of natural resources from overseas and exports them to foreign countries as processed goods. Therefore, it is discharged to a large amount of waste and domestic. 2.2 billion tonnes of resources flowed in 1996. Of these, 1.29 billion tons are discharged after becoming new stock, such as civil engineering buildings, but only 230 million tons of recycled materials are used. Less than 900 million tonnes of waste are required, and the industrial wastes, 50 million tons, are general waste. The resource company business inevitably comes into view in the drastic improvement of the resource problem.

Eco-friendly hotels are on the increase 2

●A variety of environmentally friendly services.

It is said that the environmental and health efforts of the Japan service industry are far behind compared to the West. There are only seven hotels that have been certified as Eco Mark. However, unrelated accommodations that are not livery the official ECO Mark certification are rapidly attracting attention. The accommodation has been born in various places to take the eco-trend and to put the foot on a sustainable management. In the hotel opened in the center, you can set a lot of greening area on the site, the use of old wood beds, recycled bicycles, and food loss to reduce the amount of ingenuity (devised to put out without peeling the organic carrot) and various. At a hotel in Kawasaki City, a disposable toothbrush and other waste plastic is made into solid fuel, and the electricity is taken out from there, and the story served about 30% of the power consumption of the hotel. Among the guests, "I would like to support such management, whether it is an effort to devise environmentally friendly in the place where there are a lot of inn which tries to attract customers by price competition on TV. It is not to be overlooked that the voice of "green living person" who says "it wants to contribute to the society to the extent that I can do is increasing".

●Creation of a new business on the axis of the environment. 

The US-Trump Republican regime's decline in environmental policy has continued to recede. In a CBS News interview on December 14, Trump said, "I don't know if climate change is due to human activity. I don't want to rob millions of jobs, like the coal industry. The LDP Abe administration is also akin to keeping pace with playing cards. The main theme of environmental issues is to use the phrase "realizing a sustainable society" as a word that inflame the traditional GDP (gross national product). However, it is the beginning of the development of the eco current and the new work for smart people and the industry as the action of this eco-hotel no longer. Environmental business is nothing more than a new business development on the axis of the environment.

Food waste, thinned wood and branch materials as biomass energy 2001.05.20

Biomass energy has been attracting attention as a new energy source as a waste treatment. Biomass is the idea of an organic organism as an energy resource, in addition to plant resources, such as human waste urine, garbage from plants and animals, etc. are also included. The use of biomass energy, which is currently considered, is based on incineration heat utilization, gasification by pyrolysis, methane fermentation, and alcohol fermentation. As for the use technology, the use of heat by direct incineration and the methane fermentation of organic wastes has been put into practical use, but in the food factory, the case of adopting methane fermentation technology is increasing in response to the food waste recycling law.

Approximately 2.7 billion yen has been organized for the development and dissemination of biomass energy in the environment-related budget of the country in fiscal 2001. On the other hand, the Ministry of Health, Labour and welfare has processed human waste and raw garbage, and launched the "Sludge Regeneration treatment center Concept" to recycle methane gas and compost, and issued a subsidy only for the recycling type of new human waste treatment facilities from fiscal 1998. Therefore, the municipality is looking for a mechanism that can recycle from both sides of the garbage disposal and human waste processing.

In addition, the "Renewable Energy Promotion Law" under consideration for legislation is also touted to promote the dissemination of solar and wind power and biomass energy. 19 million tons of food waste per year, and waste material discarded from construction sites is 17 million tons annually. Only biomass resources that are currently being treated as waste rise to this amount. In addition, the forest area of the current Japan is about 25 million hectares. The forest resources that grow over the years are about 100 million cubic meters Sweden. According to assets such as ministry, the Japan has been left in mountainous areas for about 6 million cubic meters of thinned wood and branch materials. We consider these to be energy resources, and if we plan to proceed deforestation and reforestation, we can diversify energy sources and preserve forests. It also leads to the promotion of forestry, which is declining steadily.

Construction, general contractors, ideas and business change are necessary now 1

Construction industry of Japan, the transition period from the newly built market to the reproduction market at the western countries level.... The condo is more than a pre-built attention! It can be said that the stock maintenance of the building of Japan (especially the renovation and repair of the building) entered in earnest in the age. It is said that there are about 8 million buildings in the country where the stock of the building which needs repairs including the commercial facility of a reinforced steel building and a detached house in addition to the house is now about. The construction industry is not scrap and build to break and rebuild these buildings, the business opportunity to achieve a longer life by renovation and repair is expanding. -Condominium, according to the study of the pre-new market flow East real Estate distribution Agency (Chiyoda-ku) and the Real Estate Economics Research Institute (Shinjuku Ward), in the metropolitan area (Tokyo, Saitama, Kanagawa, part of Chiba), the contract units of the newly-built condominium was 35952 units , the 37829 units of used condominium were close. In 2016, the second-hand was more than new construction. The reason for this is that the rise in land prices and building materials, the shortage of manpower, etc. is high and the price of new houses is rising due to the decrease in Therefore, the sales price of the condominium in the metropolitan area spreads the difference between new construction and secondhand. For example, as of 2017, new construction was about 60 million yen. If it is the same size as the purchaser, it will naturally choose secondhand. In addition, the policy and the system which promotes the circulation of the used condominium in the country is a wind. In the Ministry of Land and infrastructure to increase the stock of the condominium "is a lot of affordable and good-quality used condominiums than new construction, I want to give a chance to those who want to get home," said the ministry.

The 21st century is the era of hydrogen civilization 2 - the ene farm

As an "ene farm", "Energy farm" refers to the spread of fuel cells for domestic use as a means of fuel cell for households, and the coinage is coined by "energies" and "farm = farms". To make electricity and heat from hydrogen and oxygen. In a word, it can be said that the farm products are made by water and the Earth. "Ene Farm" is like introducing a power plant to each home in a manner of speaking. Make your own energy. Power generation and its accompanying exhaust heat can be used for heat source such as hot water and heating and cooling. Gas and oil companies are focusing on the spread of fuel cell power generation businesses since the East Japan earthquake in Tepco. Currently, there is a background that hydrogen is not the most cost of gas and oil harvesting. Since 2009, the market is being formed in earnest. As of July, 2018, a quarter of the home fuel cells were introduced, and the demonstration test was cause overturn. At that time, three companies of ENEOS, Toshiba and Panasonic were competing, but now Panasonic has one company left. 　The price is cut by two million yen. If one million yen is cut, the penetration rate might accelerate at a dash. The subsidy for the introduction is organized every year. By the way, the fuel cost is reduced by five to six million yen per year.

Low-pollution coal using agricultural wastes 1998.09.15

The experiment to make use of the molded charcoal which mixed the residue of crops such as corn into coal started in China. Keio University, the University of Tokyo, and the Central Electric Power Research Institute have collaborated with the Chinese side to set up and operate the molding charcoal manufacturing equipment in two cities such as Shenyang City. This molded charcoal is called bio-briquette, which is hardened with high pressure mixed with corn charcoal, wood scraps and slaked lime in coal powder. Slaked lime can fix sulfur content and significantly inhibit SOx generation.

Ocean Purification Business Expanding②

<A variety of organisms from Japan cross the sea and have been in various parts of the world. >

● In various parts of the world damaged by ballast water, not to be overlooked the damage by ballast (weight) water to load the ship in order to stabilize the running. Seawater loaded into the ballast tank at the departure of the Japan is discharged at Port of call. In addition to having a bad influence on the local ecosystem and the water industry as described above as an alien species, the organism of the Japan production which had been mixed has brought it to the occurrence of the health damage of the local person. Cases of damage caused by foreign organisms that are considered to be caused by ballast water. Australian farmed scallops and oyster damage caused by starfish brought from Japan, etc. Due to the proliferation of zebra shells from Eastern Europe, the closure of the inlet of the power plant on the Great Lakes Coast United States. There have been cases where one million people have been infected in South America due to the cholera bacterium that has been transferred to the Mexico Bay, and 10,000 deaths have died.

● Market size of ballast water measures: trillion yen although the damage has not been manifested at this time, there is a high possibility that new damage will occur when the growth environment of governing organisms changes in the future of climate change, the activation of economic activity of the GDP supremacy, and water pollution by industrialization and urbanization, etc. The International Maritime Organization (IMO) adopted the "Ballast Water Regulation Treaty" in February 2004. The treaty requires that new shipbuilding be equipped with equipment that properly handles ballast water since 2009. "This processing unit is expected to be in demand for more than two trillion yen in the world" (Eco-business Network Research) Other, the damage measures caused by the biological movement, it is no doubt that an immense market will be created. This is business opportunities in the marine Japan of the environmental technology nation.

Plant-derived bioplastic②

The use of forest resources is growing as an industry, and the demand for forest-related resources is increasing from the securing of new energy resources to the world. In the Japan, energy-related thermal use and power generation utilization of forest and woody biomass (lumber residue, felling, pruning wood, etc.) widely distributed nationwide are carried out in various places. Overseas, the amount of the production of the bioethanol (cellulose as a raw material) of the oil alternative of the plant origin has increased comparatively. In the Japan, the production of BA-ethanol, which uses forests and woody-based cellulose as raw materials, has begun in the demonstration phase.

On the other hand, the bio-plastic as the eco-materiel use of the forest resource has already begun production as part of the member of the electric machine and the precision equipment. The research of the new material and eco-material "cellulose nanofibers" (CNF) of the use of Bioprestik is rapidly expanding plant, it became a concrete product is Bioprestik. In eco-material development, the world's top Japan has already begun to be used in electronic equipment and automotive related materials as a reinforcing plestik, in addition to disposable diapers and ballpoint pens. The main ingredient of this plant fiber is a robust structure, such as reinforced concrete, and the strength of one-fifth of the steel is five times higher than that. Moreover, because it is carbon neutral (not emitted CO2 into the atmosphere) from a renewable plant, it also leads to suppression of global warming. The source of the raw material is the forest and the primary industry. It will become an opportunity of new industry creation, and it is a barrel material in the world of pure domestic for the forest country and the Japan. The commercialization and commercialization of Bioplestik is steadily expanding.

Ice Thermal storage Air conditioning system is selling well 1998.09.15

Ice Thermal storage type air conditioning system is rapidly spreading. The number of installations in the Tokyo Electric Power Pipe was 1990 at the end of 1997, with a 21% increase at the end of fiscal 1998. In the entire country, the 3490 in fiscal 1996 increased to 4480 in 1997. The power companies that have to build a power plant to match the peak in summer formed a sales force, and it spurred the spread that the company focused on selling the system.

Waste paper stock decreased by three consecutive months 1998.09.15

Domestic stock of old paper is decreasing trend. According to the Kanto paper raw materials and Commerce Union, the end of July inventory of the Kanto District is 61409 tons, down 3.1% compared with the previous month. The low level since the end of June 1996 with a decline of three consecutive months. Although it is a factor that the waste paper wholesaler is put power to export for the Korea and the Taiwan, the stock ratio (the proportion of stock to the shipment of the wholesaler) is 24.8%, and 15% of the level that is appropriate is still exceeded.

Environmental business that expands in multi-disciplinary environment business

<Development to all industries and all participatory businesses. >

The market size of our environmental business is steadily expanding. According to the Ministry of the Environment, the market size of 2016 was approximately 104 trillion yen, with a capacity of approximately 2.6 million employees. The market size is evident in comparison to the market size of approximately 65 trillion yen (2016) of the automobile industry, which is always attracting attention, and the construction industry of 45 and 5 trillion yen (2015).
You can understand how huge industrialization is. In the media, the energy-related reports of nuclear power plants, such as renewable energy, Smartgrit, Smart House, and eco-cars, etc. are noticeable, but the environmental business is more broadly and deeply The market is steadily expanding. It is made in the form of expanding the base of each industry greatly.

For example, in the primary industry of agriculture, forestry, livestock, and fisheries, biomass resources began to be utilized, recycling of organic wastes, permanent agriculture based on organic farming, building materials using domestic materials and thinning materials, etc., sunlight, wind, and local consumption Small hydro power generation, and the like. In manufacturing, construction, and mining, the second industry manufactures and sells a variety of renewable energies, energy saving, environmental equipment and equipment, storage batteries, fuel cell devices, etc., and the construction industry is environmentally friendly building construction, building waste recycling, etc. In the mining industry, in addition to the recycling business of waste appliances and waste automobiles, recently, businesses such as collecting and recycling rare metals such as electronic and information devices are expanding. It seems that the second industry now has more than 60% of the market size in the mainstream of environmental business. In the tertiary industry, which consists of electricity, gas, distribution, and financial services, there are a wide range of green consulting fields, including renewable energies, business proposals for energy conservation, distribution of environmentally friendly products, and environmental advertising. In recent years, businesses such as the Building Energy Management System (BEMS) and the HEMS (Home Energy Management System) have been expanding. In this way, the environmental business has evolved into all-in-all business, and the number of participating companies exceeds 10,000, and the business item rises to 900, and the steady growth factor is concealed here.

Business with global warming

The market for energy conservation, power saving, self-power generation, and storage of renewable energy is rapidly expanding, as the mainstream of the Japan earthquake and disaster waste treatment after the Tepco nuclear power plant accident, and the radioactive disasters continue to be not relying on nuclear power plants. The environmental business is formed as an all-participating market for the first to third-order industries. In the industrial world, the movement of the nuclear power plant has accelerated in the early and the government's nuclear policy. In the domestic environmental business market, it is the "resource and energy securing" of the pure domestic environment which is listed as the growth field which can be expected in the future. As a result, the industry expansion in these fields will lead to prevention of global warming and low carbon. Therefore, the global warming business is one of the opportunities for the creation of business in the environment, but it does not become the starting point of the idea of business creation. Because climate change is not a global warming phenomenon, global warming and low-carbon business opportunities will not be derived.

The original significance of environmental business The purpose of environmental business is to develop an environment that includes natural and ecological systems for the realization of a sustainable and prosperous society for the future generations, but for the past seven or eight years, environmental business has been emphasizing the "living environment" of the current generation of amenity-oriented It is beginning to deviate from the original meaning. In the political world, the borders of territorial, territorial waters and airspace are thriving, and the deterioration of the global environment related to human fate is indifferent. It is time to sincerely ask that the 21st century is the century of the environment.

Main factors of eco business market growth②

A variety of tailwinds to create an environmental business. In the environmental business development, as described above, there is a wealth and variety of related technologies and products in the Takamine market, it can be said that the tailwind state. On the other hand, related information such as the key price has come to be widely published compared with the time of B to G (public works), and the condition has become good for the enterprise which aims at entering.
　In addition, it has been linked with the greening of the global economic market. The national environmental policy has continued to push toward green. The 21st century may come into the era of environmental treaties. Because, it is not a problem which can solve one problem of PM2.5 very much only by one country. The deteriorating global environment is not a problem that can be solved very much if, for example, a neighboring country has entered into a treaty and has not dealt with it to solve the problem.

　To cope with the deterioration of the global environment at the international level, the world-renowned environmental technologies cultivated over the Japan 50 years are a powerful weapon, and business opportunities are lurking. The legal regulations are not to be overlooked. This, for example, if it is recycled legislation relates to food waste, measures against food waste that has been incinerated so far is required. The recycling device is necessary for that, and the bud that the environmental business grows there comes out. When the legal regulations concerning one environment are applied, the environment business is surely raised there. In addition, when the environmental business is to start up, the restriction accompanying this is existing oppositely. For example, if you want to renew your building when you enter the environment business, the hurdles are unexpectedly high because of the electric business Law and construction law. Then, the deregulation of the environment business which makes it easier to enter by lowering the hurdle will accelerate.

Plant-derived bioplastic②

The use of forest resources is growing as an industry, and the demand for forest-related resources is increasing from the securing of new energy resources to the world. In the Japan, energy-related thermal use and power generation utilization of forest and woody biomass (lumber residue, felling, pruning wood, etc.) widely distributed nationwide are carried out in various places.

It will become an opportunity of new industry creation, and it is a barrel material in the world of pure domestic for the forest country and the Japan. The commercialization and commercialization of Bioplestik is steadily expanding.

Main factors of eco business market growth①

The domestic environmental business market currently has 10,000 companies, and business items are expanding to around 900 and all industries. They are all part of the participatory aspect.

That is one of the growth factors of the market.

　Four entry forms for entering the market. The first is "greening the production line". That is, the production line or energy saving, not to discharge the waste as much as possible from the production line, also aims to recycle, and the like to prevent water pollution with not out the sewage outside. In this effort, each company has a large number of environmental engineering department, which has zero emissions, energy saving, and emission control of hazardous substances, and it is not uncommon for major companies to spin it off. And, the business to sell the green technology, the know-how and the experience that it created here to the other companies is not to have begun now.

The second is "greening existing products". Products that are currently traded in the world are rapidly advancing green. These days, low-pollution automobiles and energy-saving consumer electronics products are natural. In other words, we create environmentally friendly products such as energy saving and resource saving of conventional products, adoption of recycled materials, and suppression of use of hazardous substances. Thus, the load on the environment can be further reduced.

The third is the application of "core technology (business) to environmental technology (business)". This is a common case for small and medium-sized businesses, and it is our stance to apply the core and elemental technology accumulated in our company to environmental technologies. The result is, for example, making a recycling device. The case where the solar cell was made by Si (silicon) which was the leading part of the semiconductor is mentioned as a typical example.

And the fourth is "M&A (Mergers and Acquisitions), a patent takeover." This is a case in which a company buys another company which is good at environmental technology, and as a result of the acquisition, the acquisition of related patents becomes a powerful weapon in the business entry. Recently, Panasonic, a manufacturer of energy-saving home appliances, has acquired Sanyo Electric, a typical example. Sanyo Electric is known as a manufacturer of rechargeable batteries such as lithium-ion batteries. For example, considering the use of natural power to accumulate unstable renewable energy in the storage battery, it is expected to be a significant demand for M&A.

We couldn't find any cases concerning the success of biomass power generation. ① 2018.12.01

< About Woody biomass power generation >

Last year in 2017, we looked at the first international Biomass Power generation exhibition at Tokyo Big Sight.

As the renewable energy fixed price purchase system (FIT) and power liberalization became the lure of water, the venue was exhibited many power generation related facilities, and the number of visitors was many, especially in the event that the power generation business using woody biomass in various parts of Japan was started. The difficulty of woody biomass power generation of woody biomass power generation is as far as the success case of the business to be able to take profit is close to zero.Looking at this exhibition, the biomass power generation business of the Japan, in fact, was a subsidy project in the past and the present, and it seemed that it was still far ahead to become independent as the power supply which was able to take profit on a roll on a commercial base. In the case of woody biomass power generation, the purchase price of Japan fit is 32 yen per 1kw in unused timber. I hear that this is a case in which a chip of 12000 yen per ton is made a fuel in the 5MW facility by the steam turbine. However, the business operation is difficult though it set the purchase price of 42 yen last year in a smaller power generation facility than this. Therefore, the electric power of the equipment cannot help becoming a large equipment. Large-scale equipment can reduce the cost of electricity, which is more profitable. Many large-scale power generation facilities are exhibited in the venue on this day, and the introduction has been proposed and planned.

However, the reality is severe. If it becomes possible to introduce a large-scale equipment that only the priority of the thermal use than power generation is not recoverable cost high, and the equipment operation, to operate the business, the collection of the current woody biomass resources, and considering various circumstances such as efficient energy use,
The sustainable power generation business is a difficult and unreasonable story even if the subsidy is used.　So, what should I do? The answer is one.
First of all, the proper use of woody biomass based on the current situation is not the first form of power generation, and it seems that the priority of thermal use is high solid business profitability. In United Kingdom, we removed woody biomass from fit and started buying a fixed price instead of heat.

The season when the dense fog PM2 5 is coming①

In each of the cities in China, the arrival of a full-fledged winter, the heating by the poor quality coal combustion is applied, further "dense fog" (photochemical smog) by PM2-5 (micro particulate matter) is expected to occur frequently. Depending on the region, visibility has deteriorated to less than 50 meters even for a full year. In the northeast, Harbin is not seen five meters away. The effects of highway closures and flight cancellations and delays, as well as the impact on civil life, have been significant.

Especially, there is a concern about the remarkable health damage of the citizens. In the winter months in Beijing, the city has been covered with dense fog, so Japanese companies are taking precautions to refrain from going out to employees and other measures such as providing subsidies for purchasing air purifiers.

It is said that the number of expatriate employees who think about their families ' return home is increasing. In the first place, PM2-5 is a micro-particulate matter below the diameter 2.5 micrometer (Micro 1-millionth) contained in thermal power plants and plant smoke, automobile exhaust gases, fine dust, etc. Because it is easy to penetrate to the depths of the lungs, it induces asthma and lung cancer.

In the Japan of the high-growth period, Kawasaki Asthma and Yokkaichi caused asthma. Sulfur oxides (so 2) and nitrogen oxides (NOx) in PM2 and 5 are generated by burning coal, petroleum, etc. The main sources of sulfur oxides are steel mills, power plants, factories, etc. The source of the nitrogen oxide is similar to the sulfur oxide, other automobiles, ships, it is discharged in large quantities from the mobile sources such as aircraft. Dense fog in urban areas are due to sulfur oxides. Both are causative agents of air pollution, causing the collapse of ecosystems (planting and biological mortality), health hazards, etc. By the way, it is said that every year in China, about 500,000 people die from respiratory diseases.
