AbstractShenzhen is a fast growing modern city. In 1980, Shezhen was just a fishing village. With the urbanization, it extended land inside. In 2000, Shenzhen land use has already exploited 80%. With the urbanization, there are many migrant workers go to work and settle down in Shenzhen. The population grow up from 314,100to 10,357,938 in these thirty years. With the population growth, the problem is the garbage production volume increase more and more. Now, Shenzhen garbage production is 13,100t/d and the annual growth rate is 8%. There are 8 districts in Shenzhen, which is Nanshan, Futian, Baoan, Luohu, Yantian, Longgang, Guangming and Pingshan district. Nanshan, Futian and Luohu district are downtown of Shenzhen. The other districts are still in developing process. In Shenzhen, there are 9 existing landfills and 7 existing incineration plants and 23 small informal landfills. With the urbanization, the relationship between landfills and city are changing. At the beginning, landfills were set far away the city. Their distance become closer and closer when both of them extended. Until now, some of landfills has connected and existed in the middle of city. For the land use situation of shenzhen. There are 80% land use has already been exploited which means there is no more land for landfill in the future. However, the garbage volume increasing more and more and landfill is still the main way to treat garbage. It is a very serious issue need to face and solve. The garbage structure of shenzhen is, construction waste occupied 78% and 22% belongs to domestic waste. In this 22% domestic waste, food waste occupied 65%. Food waste is the biggest problem of pollution. However, the existing domestic waste treatment is still dumping the mix garbage to landfill. When food waste mix with the other domestic waste together, they will decompose and the produce a lot of biogas and dioxin and so on. It will produce serious air pollution, soil pollution and produce germs. That is why the existing landfill produce so serious pollution to the city. In other aspect, food waste is a good energy if we use it correctly. It could change to energy and fertilizer by biogas collecting, composting and chang to diesels. In Shenzhen, the government has already pay attention to garbage separation. Some communities has already implement garbage separation action. These are 3 large landfill of Shenzhen. The first one is Xiaping landfill of Luohu, the second one is Laohukeng landfill of Baoan and the yahoo landfill of Pingshan district. Base on the location situation, Yahoo landfill will be a best choice to make it as an experimental plot to plan. In Yahoo landfill, the existing landfill has already influenced thirty thousand surrounding people’s life. In future, the extension landfill will connect to the the residents area and polluted more seriously. So how to maximum reduce the pollutions is a urgent problem need to solve. The strategy is separating two part to solve garbage in this landfill. One for dumping, the other one is food waste composting. When the food waste composted to fertilizer, it will be transported to the surround farm lands to use.
