Reusable packaging is essential for reducing packaging waste and can significantly contribute to environmental protection and resource conservation compared to single-use packaging. Data from Germany show that more efforts are needed to strengthen reuse systems and combat excessive packaging consumption. This research project examines how to promote and optimise existing reusable packaging systems and explores the potential for new systems along the supply chain and in retail. This report covers findings on current applications of reusable packaging and potential measures for strengthening and expanding its use in the beverage sector.
