1) How to construct the park on the landfill
To solve the environmental problem caused by a waste disposal site in NanJiDo, Seoul city government started the construction to stabilize the environment in NanjiDo like these ways: 'landfill cover soil' construction in upper part of ground -> be smooth down the slope -> leachate disposal facility -> landfill gas disposal faci
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

Wastes in landfill emit landfill gas(LFG) which is mainly composed of carbon dioxide and methane. Methane is one of major green house gases(GHG) with carbon dioxide, and landfill is the important source of it. Otherwise, it can be an alternative energy source due to its high heat value. Therefore, an appropriate use of LFG can derive both of environmental and economical advanta
gas which produce bio-gas by putting more than two of them together, among the organic 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 20
