Sustainable concrete variants color future green

During InfraTech 2025, V.d. Bosch Beton from Almelo will present itself as an active booster of sustainable developments in the concrete industry. This happens, among other things, with Ecoton® and Reduton®, two product lines that contribute significantly to a reduction in CO2 emissions. Reason enough to visit the stand of the specialist in high-quality, sustainable paving materials. 

Over 25 years ago, V.d. Bosch managed to replace a small portion of gravel with certified concrete aggregate for the production of paving materials. In the following years, the replacement rate went up steadily and the quality of the granulate got better and better. After various bodies conformed to each other over the years and the requirements around reuse were equalized, the BRL K11002 for sustainable concrete eventually followed. "This standard means that of all products, at least 15% of the entire volume must be replaced by secondary raw materials. We are well above this," says Nils Brunink, head of field sales at V.d. Bosch Beton. "In our case, this involves recycled concrete granulate. In the meantime, the name of this product group has been changed to Ecoton® Circular Concrete, a product that we will put in full prominence during the fair."

Specialty

Moving toward a green future, replacing cement in concrete paving products using geopolymer technology is another notable achievement of V.d. Bosch. It is a process that results in extremely low CO2 emissions, without compromising quality and aesthetics. "By using recycled concrete aggregate and ECO aggregate instead of traditional gravel and additionally replacing some of the sand with ECO sand, we are committed to circularity and high-quality reuse of materials," Nils said. The result of all these efforts is the versatile Reduton® cementless concrete, since 2016 a specialty of the house that is recyclable at the end of its life cycle and can be easily reused in the concrete chain. "By switching to geopolymer as a cement substitute, CO2 emissions have been significantly reduced," explains Nils. "The MKI score is about 50% lower than that of conventional concrete with cement. In monetary terms, that roughly equates to only 10 euros per cubic meter."
