Every day, biogas of about 10,000㎥ from about 800 tons of food waste water can be refined and the refined biogas of about 6,500㎥ can be mixed with CNG in the ratio of 77 to 23 at a station. The fluid can be used for about 300 city buses and garbage trucks.
The facilities of Sudokwon Landfill Site Management Corporation are significant as the first outcome of a waste-to-energy policy. It is expected that 33,530 CO2 tons of greenhouse gas can be reduced annually by providing renewable energy and replacing fossil fuels.
Under the master and action plan for waste resources and biomass energy, the Ministry of Environment has been active in waste-to-energy policies. Besides the facilities for biogas automotive fuel of Sudokwon Landfill Site Management Corporation, the ministry has supported about 20 local governments in building facilities for producing biogas from organic wastes.
The ministry is also in the process of improving related system including streamlining licensing procedure of waste-to-energy facilities and setting up biogas automotive fuel manufacturing standards.
