C2CA Technology

C2CA Technology, now operating as Everox since 2025, was set up in 2016 as a spin-off from TU Delft and GBN Group. It focuses on upcycling waste concrete into high-quality, circular materials for new concrete production, replacing primary raw materials like cement, sand, and aggregates. Its proprietary Advanced Dry Recycling (ADR) and thermal separation technologies process demolition waste, reducing CO₂ emissions by up to 42% in the EU. Everox serves the construction industry globally, with a pilot facility in Hoorn processing thousands of tons of waste concrete since 2022 and a flagship facility in s’Gravendeel set to process 150,000 tons annually by Q3 2025. Everox’s technology supports circular economy goals and has earned the 2021 Innovation Radar Prize.
