Ⅲ. Theoretical analysis of the waste problems
We can approach to the analysis of problems to be solved at both a micro and macro level. What we will deal with is the environmental problems taking place all over China, which are characterized by a mix of pervasive influences and a number of factors. It follows that it is more appropriate to take a macro approach which enables us to see problems
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 communities and great care must be taken to avoid unsafe exposure in recycling operation and leaching of material such as heavy metals from landfills and incinerator ashes.
1. Incineration
- 쓰레기를 불에 태워 기체 중에 고온 산화시키는 쓰레기 처리방법. 소각처리라고도 한다. 폐기물 관리체계 중 중간처리 과정의 하나이며 화학적 방법에 속한다. 폐기물을 땅에 묻는 것보다 부피는 95~99%, 무게는 80~85% 줄일 수 있고 아울러 매립 공간을 절약할 수 있으므로 효과적이고 지속
