Plastic with Purpose (PwP) is a public private partnership bringing together iDE, Oceanworks, and ReForm Plastics with the purpose of developing profitable and ecologically sustainable business models in the coastal city of Da Nang, Vietnam. The program aims to improve the lives and livelihoods of small-scale, informal waste-workers, most of whom are women from across the region. This unique partnership is catalyzed by the Danida Market Development Program (DMDP) with the intention of improving the collection, recycling, and repurposing of ocean-bound plastics in Vietnam. The three pronged impact pathways of the partnership are focused on improving incomes for informal waste workers, attracting investments in profitable and scalable waste management models, and promoting the circular economy by connecting last-mile market actors in emerging markets to the global plastic credit supply chain. In this partnership, organizations in the US and Vietnam work together to leverage the global plastic credit framework by strengthening and incentivizing local waste collection supply chains and integrating them into a digital platform that is transparent and traceable.
