Challenge
With China's rapid economic growth and rising living standards, municipal solid waste has become a significant concern for Chinese cities that saw substantial increase in solid waste generation rates. Municipal solid waste was projected to continue to increase rapidly, in parallel with continuous growth and increased consumption.
China passed the Solid Waste Pollution Prevention and Control Law in 2004 and the Circular Economy Promotion Law in 2009. However, Chinese cities face significant challenges to improving waste management performance, because of a lack of comprehensive systems for waste separation, collection, transportation, treatment and recycling, as well as low public awareness and participation.
Ningbo is an important port city on the southeastern coast of China with a resident population of about 10 million. In 2009, it produced 1.19 million tons of total municipal solid waste which was all landfilled or incinerated with very limited informal separation at source. The city was determined to become an advanced and model city for municipal solid waste management and became one of the 46 Chinese cities to pioneer compulsory sorting of residential waste.

The Ningbo Municipal Solid Waste Minimization and Recycling Project assisted selected urban districts in Ningbo Municipality to increase the volume and proportion of municipal solid waste recycled with processes for separation at source and recycling and investment in its waste management system to transport, transfer and treat the separated materials. To achieve its objective, the project adopted a comprehensive set of actions including:
The project was one of China's first experiences with citywide waste separation at source systems and demonstrated effective solutions and pave the way for scale up and replication in other Chinese provinces.
