The RRRM Panel Session at WRF’23 (September 5th Tuesday, 14:00-15:30 CET) 

The RRRM Panel Session at WRF’23 (September 5th Tuesday, 14:00-15:30 CET) 

The RRRM's first panel session at WRF’23 will be held on September 5th, between 14:00-15:30 CET.

Format: Panel discussion. Hybrid (Geneva with live-streaming online) 

Concept: Contributing to WRF’23’s “Value Chains: from extractive to regenerative value chains” discussions, the session will be based on a panel discussion and open Q&A.  

This session introduces the RRRM, a multi-stakeholder initiative that focuses on the responsible production and sourcing of recycled metals. Using a collaborative approach, involving recyclers, processors, standards setters, industry associations, certification bodies, clients, and representatives of the informal sector, the Roundtable is seeking to review and connect existing bodies of work and to produce recommendations in relation to voluntary sustainability standards, guidance and tools that are applicable to the recycled metals value chain. 

The panel will explore the current drivers for change, including legislative development and downstream user expectations; how well voluntary sustainability standards and guidance currently meet these expectations and what enhancements can be made to help meet these needs. Questions will be invited from delegates for discussion by the panel.
