Turning Waste into Resources: UNRISD Explores Circular Solutions for a Zero Waste Future


Solid waste accumulation poses significant challenges to environmental sustainability. Circular economy principles offer innovative and sustainable solutions to address these challenges by converting waste into valuable resources. The United Nations Research Institute for Sustainable Development (UNRISD) has extensively explored circular solutions to achieve a zero waste future.

Circular Solutions

UNRISD highlights several key circular solutions to waste management:

  • Embrace reuse and repair: Promoting the reuse of products and components extends their lifespan, reducing the need for replacement.
  • Improve recycling: Developing efficient recycling systems to capture valuable materials from waste.
  • Implement bio-based economy: Investing in biodegradable materials and processes to diminish the reliance on fossil fuels.
  • Digitize waste data: Centralizing and analyzing data improves waste management practices and optimizes resource recovery.

Economic and Environmental Benefits

Circular solutions generate multiple economic and environmental benefits:

  • Reduced waste generation and environmental pollution
  • Cost savings through decreased waste management expenses and resource recovery
  • Job creation in sectors associated with recycling and reuse
  • Protection of natural resources by eliminating the need to extract new materials

Case Studies

UNRISD showcases successful case studies from around the world demonstrating the effectiveness of circular solutions. For example:

  • In Italy, a collaboration between manufacturers and retailers implemented extended producer responsibility (EPR) schemes to responsibly manage electronic waste.
  • In China, the city of Guiyang has achieved 93% waste reduction through stringent waste reduction and recycling initiatives.

Challenges and Opportunities

Implementing circular solutions faces challenges such as:

  • Fragmented value chains
  • Lack of awareness and access to technology
  • Limited infrastructure and financing


Circularity offers transformative solutions to address waste challenges and drive sustainability. UNRISD’s work emphasizes the need for collaborative action by governments, businesses, and individuals to accelerate the transition towards a zero waste economy.
