Where Carbon Meets Metals: Momentum Is Building

Over the past two months alone, we have received 100+ samples of alkaline wastes, with many more on the way.

• Ashes.

• Coal fly ashes.

• Metallurgical slags.

• Dusts.

• Biomass residues.

Concrete and demolition materials.

All are or have been under active investigation to scale up next-generation recycling and CO₂ mineralization solutions.

What is particularly striking is the shift in momentum. The industry has been far more responsive than we could have anticipated just one year ago, when this journey started. 

Sample after sample, study after study, using advanced characterization and modular lab reactors (gas sensors, SEM-EDS, ICP-MS, XRPD, XRF, and complementary tools), we consistently confirm, in depth :

• Significant to massive CO₂ mineralization potential

• Strong metal recovery opportunities, as either a co-benefit or a primary objective

📸 The samples shown here are EAF steel slags. In several cases, we measure up to 350 kg CO₂ per ton of slag mineralized, alongside substantial metal recovery. 

Just look at these metal inclusions! Beyond iron, chromium, and nickel, some contain molybdenum and niobium, both CRM with among the highest strategic criticality in Europe.

This is exactly where carbon management, urban mining, and industrial circularity converge. And this is what it takes: thousands of non-stop hours in the lab to build a low-carbon, circular economy.

2026 is shaping up to be a big year.
