Research on Classification and Recycling Technologies of Municipal Solid Wastes—A Case Study in Shanghai

With the improvement of people's living standard in China, the amount of municipal solid wastes (MSW) has been increasing year by year, and resulted in serious environmental issues. Developing diverse classification and recycling technologies for treating municipal solid wastes is an effective solution to such problem, which can maximizes the utilization of wastes, reduces the amount of waste disposal and improves the living environment. This paper analyzes the Shanghai municipal wastes sorting programmed and concludes the following reasons for its first-stage success, including a well-designed recycling structure, a high-value food wastes reduction and recycling system, a low value-added wastes re-utilization system, various treatment technologies and the corresponding policy supports.
