The Global Reuse Summit Programme
Welcome to the Global Reuse Summit 2025, in partnership with Ecosurety – where transformative ideas collide with real-world solutions for a sustainable, circular economy.
This year, we’re aiming for a bold 30% reduction in plastics by 2030, all through the power of reuse, prefill systems, innovation, and collaboration. Join leading voices from business, policy, and global movements as we share strategies and ignite action towards a reusable future.
Let’s shift from throwaway culture to “always” – together.
Doors open at 9:30.
The Global Reuse Summit will take place from 10:00 until 17:00 on Wednesday 12th March 2025.
