Environment and circular economy transition in China


Integrated Waste Management in The city of Xi’an

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. Xi’an used to rely on a sanitary landfill to treat its waste, but now, as one of the 46 Key Pilot Cities for mandatory waste segregation at source, it is required to have a diversified infrastructure in place including at least a few waste-to-energy (WtE) plants and a few biogas plants for treating organic waste. It is therefore in the process of a massive readjustment of its MSW management and therefore a potent area for this pilot project. Recycling is, of course, another crucial realm of city’s activities.

The project boundary of Xi’an City covers seven urban districts (Xincheng, Beilin, Lianhu, Yanta, Baqiao, Weiyang and Chang’an). Two-levels of government are responsible for waste management in the city with Xi’an Municipal Administration Bureau being the key institution at the municipal level. It takes care for the macro-management of municipal environmental sanitation as well as guides and supervises the authorities of district-, county- and development zone-levels.

Project approach & progress

Performance of Xi’an MSW Management in 2021

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

  • Technical support regarding the landfill closure, monitoring and quantification of landfill gas leakages and improvement of landfill gas collection and utilization
  • Technology and equipment selection, recommendations on design solutions for new restaurant and kitchen waste treatment plant(s)
  • Operation optimization for the restaurant waste treatment plant
  • Operation optimization for the incineration plant and technology adaptation to the changing waste composition (i.e. due to improved waste segregation at source)
  • 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
