What if a brick could absorb CO₂ instead of emitting it?In this episode of The Heald Approach Podcast, I sit down with Mat Davies, National Specification Manager at Vandersanden, to explore Pirrouet – the carbon negative brick that is rewriting what’s possible in sustainable construction.Together, we unpack:Why Pirrouet sequesters 60kg of CO₂ per tonne and what that means for net zero constructionThe cultural and regulatory barriers holding back innovation in the UKHow Vandersanden’s family-owned ethos enables long-term, bold investmentsWhy architects, clients, and contractors must collaborate if sustainability is to stickThe importance of supporting future talent through the Vandersanden Academy and RIBA initiativesThis is not just a conversation about bricks.
