The European Reuse Barometer provides an in-depth analysis of the reusable packaging landscape across Europe. It highlights the environmental and economic benefits of reusable packaging, but also recognises the significant scale required to make these systems viable. Key findings show strong consumer engagement, high return rates, and operational adaptability, especially in sectors like takeaway, retail, and e-commerce. The report underlines the importance of policy support, financial incentives, and collaborative infrastructure to overcome barriers, such as the dominance of single-use packaging and logistical challenges. The barometer ultimately aims to provide stakeholders with critical insights and support the European transition to reusable packaging through annual tracking and assessment.
