TECHNICAL SOLUTIONS

Through these steps, Carbon4Minerals aims to demonstrate the viability of its CO₂ capture and material recycling technologies, contributing to a significant reduction in CO₂ emissions while producing sustainable construction materials for the future.

Step 1

Capturing CO₂ from industrial flue gases using liquid and solid amines. Optimizing energy-efficient processes to concentrate and collect CO₂.

Step 4

Evaluating the environmental, economic, and social impacts of the project. Ensuring the sustainability and competitiveness of the new construction materials.

PILOTS

The Carbon4Minerals project will operate a total of 8 industrial pilots across various locations in Europe, aimed at demonstrating innovative technologies for CO₂ capture and the production of low-carbon construction materials. These pilots cover different stages of the process, from CO₂ capture all the way to building end-products like bricks, pavers, tiles, and cement replacements.

CO₂ Capture

Testing the advanced CO₂ capture technologies (liquid and solid amines) to extract CO₂ from flue gases emitted by steel and brick production facilities. These captured CO₂ streams will be used for downstream construction material production.

Location: ArcelorMittal steel plant (Ghent, Belgium), Vandersanden brick plant (Lanklaar, Belgium).

CO₂-negative Clinker and SCM

Create low-CO₂ cement alternatives using by-products like steel slag and recycled concrete fines. Pilot tests will include the production of carbonation clinker and supplementary cementitious materials (SCMs), replacing conventional Portland cement with much lower carbon emissions.

Location: ArcelorMittal, ETEX, Heidelberg Minerals.

Carbonation Curing

Develop sustainable construction products (bricks, pavers, tiles, and façade panels) by curing these products with captured CO₂. This process both stores CO₂ and eliminates the need for traditional cement-based materials.
