The challenge of waste is growing, but so is the opportunity to solve it. At Delterra, we focus on practical, system-level change that delivers results on the ground, working with governments, communities and partners to turn waste into value.
In 2025, we strengthened this approach across our programs, demonstrating that with the right combination of behavior change, operational improvements and market development, even the most difficult materials can be recovered and put to productive use. This report highlights what that looks like in practice and how these models can scale.
Some of our highlights from 2025:
- Established lasting sorting behavior across five villages in Bali’s Badung Regency through “No Sorting, No Collection,” dramatically increasing participation and material quality
- Launched Argentina’s first women-operated plastic washing plant, linking circular systems with inclusive economic opportunity
- Demonstrated in São Paulo that targeted interventions within existing infrastructure can convert low-value flexible plastics into viable recycled feedstock
- Advanced flexible plastics recovery in Argentina by strengthening cooperative capacity and expanding processing infrastructure
- Launched the Recycled Plastics Demand Accelerator in North America to unlock end-market demand and improve the economics of recycled materials
We are grateful for all the partnerships that enable Delterra’s impact – from our Strategic Partners providing backbone support for the entire organization through to individual households and businesses that are now sorting recyclables and organics. When citizens, businesses, government and civil society all work towards the same goals, we can achieve the transformational impact needed.
