Circular home, Ghent

Something special is in the making in Ghent – and it has the potential to change the way we think about sustainable living. Talented local architect Stephan Monten is creating a unique private home built with our Carbstone building blocks, which are revolutionizing the construction industry. The process of building this home represents a new wave of environmental awareness in architecture. Keep an eye on this project – it just might be the future of sustainable living!

Project Cofinimmo Mechelen

Contractor company Vanhout shared with us in this world first during the circular and_CO2-neutral renovation of Cofinimmo’ s office building in Mechelen, which also houses OVAM’s headquarters. Although the work there is not yet completely finished, below we would like to show you some photos of the Carbstone walls that have already been erected.

Project Iceberg

With our Carbstone building blocks, we also contribute our (CO2-negative) bit to Project Iceberg, a European collaboration between 35 partners (including Colruyt Group and Orbix) from no less than 10 different countries that strives for a circular economy of building materials. This project focuses on the development of new, cost-effective, and especially smart solutions for the improved recovery of secondary raw materials throughout the circular value chain: from discarded building materials to new construction products designed with circularity and resource efficiency in mind; and containing 30 to 100% recycled materials with a high degree of purity (>92%).

This project uses granules from the demolition of old Colruyt stores. These are upcycled and supplemented with Carbinox to then cure in our CO2 drying chambers. Thus, construction waste is converted 100% into new, high-quality building blocks with a negative CO2 balance. After all, more CO2 is absorbed during production than emitted, and moreover, even after processing – provided they are placed outdoors – the blocks will continue to absorb CO2. All this is done under the watchful eye of VITO, a Flemish independent research organization in the field of cleantech and sustainable development.

Training Complex, KRC Genk

KRC Genk is investing in the future with the construction of a new, ultra-modern and sustainable training center for their youth teams! For the walls of the complex, both our CO₂-negative Carbstone blocks and the innovative Carbstone Soundblox are being used. The facing blocks provide a solid foundation for all utilities, while the sports halls are acoustically optimized thanks to the Soundblox. A sustainable project that gives young talents every opportunity to grow. The training center will open its doors at the end of 2026.

Community Center Ten Bercle, Pervijze

Bouw & Renovatie has completed the new Ten Bercle community center in Pervijze. Thanks to the use of our Carbstone building blocks instead of traditional masonry blocks, a remarkable 37,384 kg of CO₂ has not been emitted into the atmosphere. A sustainable project that offers young talents every opportunity to grow. The training center will open its doors at the end of 2026.

Changing rooms for football team RCFC Cappellen, Kapellen

The construction of the new building for the football team RCFC Cappellen, equipped with climate-neutral changing rooms, has been successfully completed. These sustainable spaces, created with our CO2-negative Carbstone blocks, are fully ready for the youth players. The construction has removed no less than 40 tons of CO2 from the air.
