Sika has developed a new, ground-breaking recycling process for old concrete. The old concrete is broken down into the individual parts gravel, sand and limestone in a simple and efficient process, which also binds about 60 kg of CO2 per ton of crushed concrete demolition waste. This innovation - with the brand name “reCO2ver” - will make a significant contribution to reduce the ecological footprint of the construction industry. Comparative testing of the Sika «reCO2ver» process has demonstrated that new concrete containing recycled content performs similarly to an all-new product. Thanks to additionally developed chemical additives, further process optimizations can be achieved, such as the flexibility to tailor specific concrete functionalities. Frank Hoefflin, Chief Technology Officer, states: “With our strong expertise in concrete technology, we were able to develop a completely new recycling process that can be considered a game changer in the concrete industry. We are already developing complementary chemical additives and quality enhancers and are pushing the industrialization of our new technology.”
