In Shanghai, environmental protection and urban cleanliness are supported by industrial and solid waste resource-recovery operations managed by a municipal corporation. This system plays a significant role in reducing waste by recycling more than 1,000 different types of materials.1

The range of materials processed through these recovery operations is extensive, including:
* Plastic
* Chemical fiber and residues
* Machine components
* Oil and grease
* Rags
* Human hair
* Animal bones1

By systematically recovering these diverse materials, the city is able to mitigate some of the environmental challenges associated with its status as a major industrial center.1
