Sika Gains Financial Support for Concrete Recycling Technology

Sika’s reCO2ver® technology is receiving targeted support as part of a climate protection program. The technology involves a concrete recycling process that allows old concrete to be entirely reused while facilitating the sequestration of CO2. To support the use of the technology, Switzerland’s Climate Cent Foundation is guaranteeing the purchase of CO2 certificates from the program for an initial amount of CHF 10 million.

Sika’s reCO2ver® technology not only separates old concrete into the high-quality individual components of gravel, sand, and cement stone; it can also bind additional CO2 through a chemical process. Around 15 kilograms of CO2 per tons of concrete demolition waste can be stored over the long term. On top of this, the performance of the cement stone powder produced during this process is optimized using Sika additives. This allows it to be repurposed as a substitute for cement in concrete production. A pilot facility has been operating in Switzerland since October 2021, and the test phase has now been completed successfully.
