In this episode of The Nexus ReGen Podcast, host Will Rundle is joined by Ben Winch, a leading voice in sustainable soil reuse and Associate Director at RSK Geosciences.

Together, they explore what it takes to build a circular soil economy in construction — one where excess materials are no longer treated as waste, but as valuable, reusable resources.

🔍 Topics include:

• What an MMP (Material Management Plan) really is — and why timing is everything
• The commercial and environmental benefits of treating soil as a resource
• Common pitfalls that lead to avoidable landfill costs
• How early engagement, good documentation, and collaboration between sites can unlock huge savings
• Why platforms like Soil Link are key to enabling cross-project material sharing at scale

This is a must-listen for developers, contractors, ground workers and sustainability professionals looking to stay ahead of regulation, reduce cost, and improve environmental outcomes.
