Carbon Upcycling Technologies is proud to announce our selection for the 2026 Holcim MAQER Ventures Accelerator, joining a cohort of construction technology startups working to reshape how the world builds.

The Holcim MAQER Ventures Accelerator connects high-potential companies to the global operations, R&D infrastructure, and partner network of Holcim, one of the world’s leading building materials companies. With 42 startups accelerated to date, the program has established itself as a launchpad for innovation in sustainable construction.

This year’s accelerator features Amazon as a corporate partner alongside Acciona, Bouygues Construction, Schneider Electric, and SUEZ.

What’s Ahead

We will work with Holcim and Amazon to test, validate, and scale our low-carbon supplementary cementitious materials (SCMs) in real-world applications. Our SCMs are produced from upcycled industrial byproducts and captured CO₂, offering a locally sourced, scalable pathway to decarbonized concrete without compromising performance. For developers constructing at the scale and pace that modern infrastructure requires, materials like ours provide a local, reliable, and clean solution they can depend on.

We look forward to sharing progress as the program unfolds.
