The “praxPACK” project explored reusable packaging solutions for e-commerce over three years, aiming to reduce environmental impact. Key findings showed that while reusable packaging can lower waste and emissions, its adoption is hindered by high costs and inefficient return logistics. Collaborative return systems and standardisation across providers were identified as potential solutions. The pilot partners reported positive customer feedback but faced logistical challenges. The project calls for continued efforts toward shared return infrastructure and industry cooperation to make reusable packaging more feasible in e-commerce.
