Ⅰ. 개요
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%.

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
waste in developing countries may cause serious health and pollution problems, though these countries are most likely to reuse and repair electronics. Some electronic scrap components, such as CRTs contain contaminants such as lead, cadmium, beryllium or brominated flame retardants. Even in developed countries recycling and disposal of e-waste may involve significant risk to workers and communiti
