About 70% of Shanghai's garbage disposal is in Shanghai Laogang Solid Waste Base. However, the speed of garbage disposal in the base can't keep up with the speed of garbage production. Therefore, it is reported that the first phase of Laogang Wet Waste, a major project in Shanghai and the largest wet waste resource treatment project in Shanghai, will be put into operation at the end of next year.

compost

Domestic waste is piled, stored and fermented at the temperature of 55~70℃, and organic matter is decomposed into inorganic nutrients with the help of microbial decomposition ability in waste. After composting, domestic garbage becomes sanitary and odorless humus. It can not only solve the way out of garbage, but also achieve the purpose of recycling. However, domestic waste compost has low nutrient content and high impurity content, which is easy to cause soil hardening and groundwater deterioration after long-term use, so it needs to be strictly separated in composting pretreatment or post-treatment unit.

It is imperative to study the comprehensive management technology. On the one hand, the main obstacle to the resource utilization of garbage lies in the complex composition of garbage itself and the difficulty of resource utilization.

On the other hand, the research and development of related technologies has not kept up. The existing utilization technology often adopts a single mode (such as incineration for power generation) to treat different garbage components in the same way, which leads to large consumption and poor economy in the treatment process itself. Therefore, it is of great significance to study the key technologies of comprehensive treatment according to the different components of garbage according to local conditions, which is a major event related to the national economy and people's livelihood.
