Single-use packaging is a primary cause of the plastic and climate crises. Reuse is the most effective solution. PR3’s mission is to enable and accelerate the alignment and scaling of reuse systems around the world. Over three years, drawing on input from across the value chain, PR3 created system design standards meant to align returnable packaging –regardless of producer– with shared infrastructure for collection, washing, and transport. Through this work, PR3 has become a hub for solutions in the global plastic reduction and reusable packaging systems space.
