Sika’s innovative reCO2ver® technology is now receiving targeted support as part of a climate protection program. The technology involves a novel 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.
