Breakthrough in concrete recycling

According to the European Commission, 25% to 30% of all waste generated in the European Union (EU) consists of construction demolition waste materials, much of which could be recycled.

Sika has succeeded in developing a ground-breaking old concrete recycling process, whereby they are able to separate and reuse the components of old concrete as well as increase the recycled aggregates’ quality. This innovation – with the brand name «reCO2ver» – will make a significant contribution to reduce the ecological footprint of the construction industry.

Sika’s chief executive officer, Paul Schuler, comments: “With the complete recycling of these materials, up to 15 million tons of CO₂ emissions can be captured. We are convinced that our new process has the potential to benefit both our customers and the environment.”

Additives for high-performance concrete

Frank Hoefflin, chief technology officer, stated that with their strong expertise in concrete technology, Sika has developed a completely new recycling process that can be considered a game changer in the concrete industry.

Comparative testing of the Sika «reCO2ver» process has demonstrated that new concrete containing recycled content performs similarly to an all-new product.

Hoefflin concludes: “We are already developing complementary chemical additives and high-quality enhancers such as the flexibility to tailor specific concrete functionalities. We are pushing the industrialisation of our new technology.”
