As the leading partner for sustainable construction, Holcim aims to apply Capsol's technology to further advance its decarbonization roadmap and drive profitable growth.

Ram Muthu, Head of Operational Excellence, Holcim: "By combining Holcim's expertise in cement manufacturing and on-site carbon capture with Capsol's safe and efficient technology, we have an additional lever to advance decarbonization and drive profitable growth. Through this strategic investment, we are one step closer to producing near-zero cement at scale to meet growing customer demand."

Wendy Lam, CEO, Capsol: "Holcim is a leading provider of sustainable construction solutions and one of the largest cement producers in the world. They have bold ambitions of producing near-zero cement at scale for customers. Capsol wants to be part of realizing this ambition.

We look forward to further developing our relationship with Holcim and innovating together for the future."
