Ⅰ. 서론
일반폐기물은 발생에서부터 최종처분에 이르기까지 다양한 환경문제가 나타날 수 있다. 먼저 여러 종류의 폐기물이 복합적으로 발생되는 생활쓰레기의 처리과정에서 가장 많은 비용이 지출되는 수집·운반과정에서 발생되는 문제로써, 음식물 및 채소류와 같은 유기물질의 부패에 의한 악
waste gas, waste water gas, livestock· sewage gas, sewage sludge gas, depending on the type of organic 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 (biog
waste is the primary output as a residual at the end of the material flows and a lot of pollutant released in waste disposal process is the additional output. We found also a notable fact that Chinese’s immature citizens and environment consciousness has a great deal of influence on the overfull output.
And last, the overfull output comes from the overfull input. The reasons the amount of inpu

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
PHB`s Separation & Purification
Target of this study conducted to obtain a purely material PHB purification process debris in the damaged cells, and to remove the remaining medium components. PHB has been removed during the refining process with just remove the present efficiency of the overall purification stayed in the 70-80%.
PHB Synthesis Pathway
