What everox does
everox (legal entity C2CA Technology BV) is a Dutch circular concrete technology company founded in 2016 as a spin-off from TU Delft and GBN, headquartered in Rotterdam. Its core offering is a patented end-to-end upcycling process that transforms end-of-life concrete into four drop-in substitutes for virgin cement, sand, and gravel: Activated Cement Paste (ACP), Recycled Coarse Aggregates, Recycled Fine Aggregates, and Fine Inert Filler. The process combines advanced crushing, separation (Advanced Dry Recovery and Heat Accelerated Separation), and activation technologies, with LIBS-based real-time quality monitoring at the pilot and commercial scale. ACP can replace up to 30% of new cement in concrete mixes, and the company cites CO2 reductions of more than 90% versus traditional cement production.
The company operates an enterprise B2B model with three revenue streams: sale of upcycled concrete materials to concrete producers, licensing of its patented technology to partners building upcycling plants, and co-investment/operation of commercial upcycling facilities via joint ventures. Customers are construction companies, demolition firms, recycling hubs, and government infrastructure agencies. The flagship 's-Gravendeel plant (150,000 tons/year) is being built with Dura Vermeer (operational Q3 2025), with expansions targeted in Canada (RALMAX JV), Ukraine (S3 mobile deployment), and additional European and North American sites over three years.
Revenue is not yet disclosed; the first commercial plant is at the cusp of commissioning in late 2025. The company has raised approximately €22.5M in equity and grant funding since 2023, including a €10M Series A in November 2024 and €12.5M from the EIC Accelerator in August 2025, with a Series B earmarked for 2026. Leadership includes a CEO with cement-industry R&D experience (ex-FLSmidth), a CCO with 20+ years in cement and concrete, and a CSO from the University of Oulu.
