September 12, 2024 – A new joint venture between Dura Vermeer and C2CA will establish a facility expected to reduce CO2 emissions by 30,000 tons per year through the upcycling of concrete rubble. In addition to recovering gravel and sand, the innovative process will also produce a supplementary cementitious material (SCM), which can replace cement in the production of new concrete.
The first facility, located in the Rotterdam region, will be capable of processing 150,000 tons of concrete rubble annually. This will position the company as a key supplier of circular concrete raw materials for new construction projects in the Netherlands. The facility is projected to be operational by the second quarter of 2025.
The upcycling process begins with the intake of pure concrete rubble, which is carefully processed into its original components: gravel, sand, and cement stone flour. In the final processing phase, the recycled cement stone flour is activated into a reactive binder (SCM). These circular concrete raw materials are then supplied to concrete producers, enabling them to produce new circular concrete with a significantly lower CO2 footprint.
