DOWA HOLDINGS CO., LTD.
BIODIESEL OKAYAMA CO., LTD. (Headquarters: 3-1 Kaigan Dori 1-chome, Minami-ku, Okayama-shi, Okayama; Capital: 99 million yen; President: Yoshiro Ishihama), a subsidiary of DOWA ECO-SYSTEM CO., LTD. (Headquarters: 14-1 Sotokanda 4-chome, Chiyoda-ku, Tokyo; Capital: 1 billion yen; President: Minoru Tobita), which is a subsidiary of DOWA HOLDINGS CO., LTD. (Same location; Capital: 36.4 billion yen; President: Akira Sekiguchi) have obtained permission to construct a municipal waste treatment facility dated September 10, 2019, and will begin constructing a biomass power plant that will use food waste as the material.
Since 2009, BIODIESEL OKAYAMA CO., LTD. has been manufacturing and selling biodiesel fuels, which are made from waste edible oil, jointly with the city government of Okayama. The cumulative total sales are approximately 5,200 kiloliters (as of August 31, 2019). Biodiesel fuel is used for garbage trucks, fixed route buses, and other diesel vehicles, and BIODIESEL OKAYAMA CO., LTD. has been contributing to the effective use of food waste and reduction of consumption of fossil fuels.
To further promote the effective use of food waste, which is difficult to recycle into fodder or fertilizers, BIODIESEL OKAYAMA CO., LTD. will begin biomass power generation using food waste as the material. Biomass power generation using methane fermentation is deemed promising as a self-reliant and decentralized renewable energy that makes effective use of local resources. The plant to be constructed is planned to accept approximately 16,000 tons of food waste every year, generate power by using methane fermentation, and generate and sell power equivalent to annual consumption of around 1,600 households.
Reduction of generation and effective use of food waste is an important task for building a sustainable society.
In Japan, initiatives have been taken in response to the Law on Promotion of Recycling and Related Activities for Treatment of Cyclical Food Resources, which was established in 2000. Of approximately 27 million tons of food waste that was generated annually, approximately 17 million tons of the waste was recycled into fodder, fertilizers, and other resources. The remaining approximately 10 million tons of food waste was disposed of by incineration, landfilling, or the similar methods (estimates for FY2016*1). Further initiatives are deemed necessary for reducing the generation and making effective use of food waste.
