What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
waste. Because they are artificial, they has about 10-15 percent higher methane (CH4) content than normal landfill gas.
Amount of organic waste is approximately 8,300tons/year by 2008 and 2007, among which only about 7% (6.1million tons/year) are used to source of energy (biogas).
Bio-gas produced by using organic waste were used mostly as a heating fuel of the dige

1978년에 발생된 「러브 캐널」사건으로 과거에 투기된 유해 폐기물에 의해 오염된 토양의 정화 책임 문제를 유효하게 대처하기 위하여 1980년에 「포괄적 환경대책 보상책임법(CERCLA, 통칭 수퍼 펀드법)」이 제정되었고, 그 후 1986년에 이 법은 대폭 개정되어 「수퍼 펀드 수정 및 재수권법(SALA
wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to ha

fuel through partial oxidation. The coal is fed into a high-temperature pressurized container along with steam and a limited amount of oxygen to produce a gas. The gas is known as synthesis gas or syngas and mainly consists of carbon monoxide and hydrogen. The gas is cooled and undesirable components, such as carbon dioxide and sulphur are removed. The gas can be used as a fuel or further process
fuel. Fuel cell is the bright prospective technique and it already spreads out in many industrial field like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development is still slight. To develop fuel cell technique as the core industry, we have to construct effective infrastructures from extraction to supply. So, in this project, our team has sea
