Building the future - we realize your projects with CarStorCon® technology.

CarStorCon® - Carbon Storage Concrete

CarStorCon® Technologies is a company founded in Marienhafe in 2022. Since January 2026, the company has been based in Dülmen, Germany.

CarStorCon® stands for Carbon Storage Concrete– the permanent storage of technical carbon in concrete applications. 

Due to the immense quantities involved, we see the incorporation of ClimAdd® in concrete applications as the greatest lever for contributing to the decarbonization of the construction industry. 

Even though we have now also successfully introduced our additive into asphalt, concrete remains our core area of application. 

Regional waste streams and storage directly in the product make the technology a local climate protection technology with a global impact.

We look forward to your inquiry

Act locally - protect the climate globally

We started in 2022 with projects in the DACH region. Now our customers come from all over Europe. We implement the projects with local partners, coordinate recipes, and ensure optimal incorporation of the Clim@Add® additive.

Biochar carbon removal is a technology that is already available and proven. Instead of being stored in reservoirs, for example, the CO2is bound in our product. No further infrastructure adjustments, such as pipeline expansion, are required. 

Regional waste streams and storage directly in the product make the technology a local climate protection technology with a global impact.
