A global network helping cities transform waste into resources

The Waste to Resources Network supports cities to develop innovative waste management systems that reduce waste generation, increase recycling and diversion, and create circular economies.

As part of C40’s wider work on waste management, the network helps cities take a holistic approach to sustainable materials management, from waste reduction and reuse to recycling, composting and treatment. 

It supports cities working towards the C40 Towards Zero Waste Accelerator, where cities commit to reducing municipal solid waste generation by 15% and cutting waste sent to landfill and incineration by 50% by 2030.


Core areas of action for achieving zero waste goals

Waste reduction

Preventing and minimising waste generation through restricting specific material streams like single-use items, incentive systems to change behaviour, and strengthening circular lifestyles through zero waste options such as reusable products and repair cafes.

Diversion from landfill and incineration

Improving the quality of material streams through segregated collection, programmes and campaigns for recycling and reuse, and deploying circular economy principles.

Food and organic waste management

Implementing opportunities for avoidance, utilisation and treatment of food waste, and improving the potential of carbon offset and sequestration.


How the Waste to Resources Network supports collaboration between cities

The network enables cities to:

  • share knowledge on waste reduction and circular economy approaches
  • learn from cities already delivering results, including San Francisco which leads the network
  • access support to meet C40 Zero Waste Accelerator commitments
  • develop programmes and public campaigns for enhancing recycling and reuse
