Turning Industrial CO2 and Waste into Low-Carbon Bricks and Cement

constructionPilotedTRL 6

Imagine taking the smoke from a factory and the leftover scrap from a steel mill and mixing them together to make a brick. Instead of releasing pollution into the air, the carbon gets trapped inside the building materials. It's like turning industrial trash into a permanent stone storage for greenhouse gases.

The business problem

What needed solving

The cement industry is responsible for 6-8% of global GHG emissions and is facing a shortage of low-carbon resources like blast furnace slag and coal fly ash as steel and energy sectors transition.

The solution

What was built

Eight industrial pilots that capture CO2 and convert industrial waste into carbon-negative bricks, pavers, and cement-based residues.

Business applications

Who can put this to work

Cement Production
enterprise
Target: Cement plant operator

If you are a cement plant operator dealing with high CO2 emissions from limestone calcination — this project developed carbonation clinkers and SCMs that can lower CO2 emissions by 80-135% compared to reference materials.

Steel Manufacturing
enterprise
Target: Steel mill with slag waste

If you are a steel mill dealing with massive amounts of slag waste — this project developed a way to use that slag to create carbon-negative facing bricks and pavers through direct carbonation.

Construction Materials
mid-size
Target: Precast concrete manufacturer

If you are a precast manufacturer dealing with the need for greener product lines — this project developed carbonation-cured facade panels and roof tiles using captured CO2 and industrial residues.

Frequently asked

Quick answers

How does this affect the cost of carbon capture?

The project uses two technologies to lower costs: a 3rd generation liquid amine solvent with energy consumption below 2.4 GJ/tonne and porous structured sorbent materials.

Is this technology tested at an industrial scale?

Yes, the project is building and operating a total of 8 industrial pilots across the entire value chain from capture to final product.

What are the IP and licensing options for these materials?

Based on available project data, specific licensing terms are not listed, but the project includes technology providers and industrial partners to validate economic feasibility.

How does this align with EU environmental regulations?

It directly supports the European Green Deal targets of 40% GHG reduction by 2030 and climate neutrality by 2050.

When will these products be available for the market?

The project period runs until June 30, 2027, with current work focusing on the design, construction, and commissioning of the pilots.

Consortium

Who built it

The consortium is heavily industry-weighted with 8 industrial partners (57% ratio), including 2 SMEs, ensuring the research is grounded in commercial reality. With 14 partners across 7 European countries, the group combines academic research (3 universities, 2 research centers) with the practical needs of steel and cement producers.
