About this listen

Welcome to the The Material Mix, the new podcast from Holcim where we explore the future of materials, innovation, and sustainable construction across the UK.

Our first episode, Mind the Carbon Gap is all about cement: a material we rely on to build almost everything around us, but one that also comes with a fairly significant carbon footprint.

Cement manufacturing is responsible for roughly eight percent of global CO₂ emissions. With the UK committed to reaching net zero by 2050, the pressure is on to rethink how we make and use this essential material.

Across this episode, we’ll unpack the innovations, policy shifts, and industry-wide collaborations shaping the next generation of low-carbon cement. And we’ll take a closer look at some of the solutions already underway, including Holcim’s own upcoming carbon capture project.

Featuring:

Hannah MacInnes, Broadcaster & Host

Tom Redfearn, Head of Sustainability at Holcim

Leon Black, Professor of Infrastructure Materials, University of Leeds

Diana Casey, Executive Director, Energy and Climate Change, Mineral Products Association
