Environment and circular economy transition in China


Integrated Waste Management in The city of Lanzhou

Background and objective

The NAMA Support Project China Integrated Waste Management (IWM NAMA) 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. Having a rather diversified system of waste treatment, the city of Lanzhou wanted to optimize it to ensure stable performance as well as to make use of data generated by various monitoring systems applied by the city to control its MSW management. As a pilot project under IWM NAMA, the application of composting as a novel approach to waste recovery and a successful roll-out of mandatory waste segregation are two focus points of Lanzhou in the coming years.

The project boundary of Lanzhou City includes Chengguan, Qilihe, Anning and Xigu Districts, covering an area of 1,088 square kilometers. The Lanzhou Municipal Management Committee has two divisions which are responsible for the environmental sanitation and MSW management.

Project approach & progress

Performance of Lanzhou MSW Management in 2021
How would IWM NAMA project support the city to improve integrated waste management

  • Operation optimization for the incineration plant and technology adaptation to the changing waste composition (i.e. due to improved waste segregation at source)
  • Recommendations and guidelines to enhance supervision of the environmental performance, operation and management of incineration plant and restaurant waste treatment plant
  • Operation optimization for the restaurant waste treatment plant
  • Recommendations on design and engineering
  • Solutions for a composting plant, treating kitchen and garden waste
  • Guidance on enhancing supervision of the environmental performance and management of the incineration plant and the restaurant waste treatment plant
  • Capacity-building & policy recommendations to improve the system of source waste segregation
  • Technical know-how & advice on IT solutions to improve data collection and management on MSW and GHG emissions from the waste sector
  • Awareness-raising to promote waste segregation at source
