94 David Peck – navigating the risk of Critical Raw Materials

Circular Economy Podcast - 94 David Peck – navigating Critical Raw Material risks

Catherine Weetman talks to David Peck, Associate Professor at TU Delft. David explains why we need to know more about Critical Raw Materials – what they are used in, and how we might navigate the future challenges they present.

David Peck is Associate Professor, Climate Design & Sustainability, Circular Built Environment and Critical Materials, Faculty of Architecture and the Built Environment, at Delft University of Technology (TU Delft).

David researches and teaches in the field of circular design, focusing on remanufacturing and critical materials. He is a founding member of the Circular Built Environment Hub and works cross disciplinary on circular challenges, in particular on digital, ICT, mobility and renewables fields.

David explains how Critical Raw Materials (CRMs) are defined, helping us understand why they are ‘critical’ from the perspective of different countries or regions, and how they are assessed and scored.

We discuss the pressure on CRMs, particularly from the perspective of low-carbon technologies, and how this presents ethical dilemmas around ‘fair shares’ for countries, and even across different industry sectors.

I ask David about the conversations he’s having with businesses and policymakers, and whether he’s noticing positive trends towards a good understanding of CRMs, and a recognition of the complex issues and risks.

We discuss the ethics and other issues around mining, and David unpacks the dangers of over-simplifying the arguments for avoiding more mining.

Podcast host Catherine Weetman is a circular economy business advisor, workshop facilitator, speaker and writer.  Her award-winning book: A Circular Economy Handbook: How to Build a More Resilient, Competitive and Sustainable Business includes lots of practical examples and tips on getting started.  Catherine founded Rethink Global in 2013, to help businesses use circular, sustainable approaches to build a better business (and a better world).
