Environment and circular economy transition in China


Integrated Waste Management in The city of Suzhou

Background and objective

The NAMA Support Project China Integrated Waste Management (IWM NAMA) project aims to reduce GHG emissions of China’s waste sector and induce a transformational change in the way waste is handled through increasing the attractiveness of IWM and waste-to-energy solutions as financially sustainable low-carbon investment options. Suzhou is one of the economic powerhouses in Eastern China and also one of the 46 Key Pilot Cities for mandatory waste segregation at source. In the scope of IWM NAMA, the city is working hard to lead in the implementation of a new waste management system and to ensure that it is low-carbon, sustainable and that various waste streams are treated efficiently and in an environmentally friendly manner.

The project boundary of Suzhou City includes five districts (i.e. Gusu District, Gaoxin District, Wuzhong District, Xiangcheng District and Suzhou Industrial Park), covering 4,044 square kilometers in total. The Suzhou Municipal Administration Bureau and the Environmental Health Administrative Office are the authorities responsible for environmental sanitation management and MSW treatment.
