Carbonatation: solution to CO2 issues?
Traditional sintering processes are energy-intensive and rely on fossil fuels, generating vast amounts of CO2. Carbonatation involves sequestering CO2 by chemically binding it with alkaline materials, forming stable carbonate compounds. This capture process eliminates carbon emissions; even better, it eliminates the CO2 emissions of other processes simultaneously. It enables industries to transition toward net zero by lowering their carbon footprint. Additionally, carbonatation can enhance material properties in certain products, contributing to a circular economy by reusing CO2 as a valuable resource in building materials like concrete and ceramics.
How can you start with carbonatation?
At CEE, we promote carbonatation technology. Our patented full-scale section lab, designed for practical tests, is a testament to our commitment to innovation. It enables the development and refinement of carbonatation techniques at scale.
The carbonatation process begins by introducing CO2 into an alkaline-rich environment, where it chemically binds with materials like lime or slag, forming calcium or magnesium carbonates. This reaction not only reduces atmospheric CO2 but also creates durable byproducts that are valuable in industries such as construction. Our advanced simulations explore various angles to enhance the efficiency of carbon absorption and optimize the integration of this process across different industries.
By absorbing CO2 emissions in these disruptive new production processes, our technology directly tackles key industry challenges like decarbonization and regulatory compliance. This empowers industries to transition toward cleaner, climate-positive production methods while driving innovation and sustainability in high-emission sectors.
How can CEE support you in this process?
CEE can provide several process components for manufacturing building products using carbonatation:
- drying the raw material with recovered heat or a heat pump
- forming and curing in CO2-controlled curing chambers using CO2 expelled by another process
In what sectors can carbonatation be used?
Carbonatation can be applied in several industrial sectors; at CEE, we focus on applications in the construction sector. Integrating carbonatation drives sustainability and circular economy practices by reusing captured CO2 in products.
Brick manufacturing
It can make the brick production process 100% fossil fuel independent and even generate CO2-negative bricks.
Concrete manufacturing
It reduces CO2 emissions by converting the raw material into carbonates.
Ceramic industry
It enhances material properties while capturing emissions.
