Cementing Carbon

Cementing Carbon31 okt 20251 u 01 min

Welcome to a pivotal conversation on the future of our built world. The concrete industry, indispensable for modern infrastructure, is facing an urgent mandate: reconcile its foundational role (pun) with its role as a source of environmental pollution. The scale of the emissions are staggering - if global concrete manufacturing were a country it would be the 3rd largest emitter, behind only China and the US (!). The good news is that with this a motivation the global concrete industry is now rethinking its entire lifecycle.

In this episode, host Kristof sits down with John Mead, one of the founders of Solid Carbon to talk about efforts to transform concrete from a carbon emitter into a "net carbon sink. By converting waste carbon materials, wood being one, into a mass of solid carbon through pyrolysis and then using this carbon sink in a durable material through concrete we are making a huge impact in an industry that needs to make some powerful shifts in the years ahead.
