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. The supporting measures include:

  • Technical support regarding optimizing the efficiency of waste treatment facilities
  • Policy recommendations on upgrading an integrated waste management system
  • Capacity-building on “best practices of IWM”, introduction of EPR, waste prevention/3Rs etc.
  • Awareness-raising to promote waste segregation at source

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.

How would IWM NAMA
project support the city to improve its
integrated waste management?

Technical support regarding the landfill closure, monitoring and quantification of landfill gas leakages and improvement of landfill gas collection and utilization

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 the 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

GHG emissions from the waste sector*

  • Business-as-usual (BAU) scenario (tCO2e/y)
  • Integrated Waste Management (IWM) Scenario (tCO2e/y)
* the GHG emissions data provided for the year 2022 (both BAU and IWM Scenarios) is indicative. The emissions associated with the IWM Scenario are forecasted by the project team on the basis of activities that are to be implemented within the scope of the IWM NAMA project under its direct (technical assistance) and indirect (framework conditions) support. Every year, the actual data on emissions will be updated as result of GHG emissions monitoring and published on the website.
