Based in Rotterdam, Netherlands, everox is a materials technology company that upcycles waste concrete into sustainable building materials to replace virgin aggregates, sand, and cement in new concrete production. The company operates a demonstration facility in Hoorn capable of processing up to 1,000 tons of waste concrete for commercial construction projects under the Dutch Climate Envelope initiative. Operating with a workforce of 21 to 50 employees, the firm targets a domestic market where approximately 13 million tons of waste concrete are recyclable annually. The venture-backed startup has secured seed funding from lead investor Chrysalix Venture Capital alongside early financial backing from PI Impact to scale its separation technologies. Originally known as C2CA Technology before rebranding in 2025, everox was founded in 2016 as a research spin-off enterprise by co-founders GBN Group and TU Delft.

Everox (formerly C2CA Technologies) is a Dutch cleantech company that upcycles waste concrete into high-quality drop-in substitutes for virgin cement, sand, and aggregates, addressing CO2 emissions from cement production (8% of global total) and the 300 million tons of annual construction waste in Europe.[1][3][4] Its patented process enables a circular supply chain, turning construction-demolition cycles into recyclable materials, with real-world validation in six Dutch projects and a pilot processing thousands of tons since 2022.[1][2] Serving construction firms and infrastructure projects, Everox tackles resource overconsumption and emissions, with growth including seed funding in 2022, a full demo line in 2023 (1,000 tons processed), investments from PI Impact (2024) and Taaleri (2024), and a flagship factory set for 2025 to handle 150,000 tons annually in partnership with Dura Vermeer.[1][6]
Everox originated in 2016 as C2CA Technology, a spin-off from a European research project in partnership between GBN Group (a construction firm) and TU Delft (Delft University of Technology).[1][4] This collaboration leveraged academic research on density-based and thermo-mechanical separation to upcycle concrete rubble, earning the 2021 Innovation Radar Prize for the most promising EU-financed innovation.[4] Early traction came from a pilot facility in Hoorn, Netherlands, operational since 2022, which processed thousands of tons and demonstrated industrial viability; a seed round in 2022 funded field demos, leading to commercial milestones like materials used in Dutch Climate Envelope projects.[1] Rebranded to Everox in July 2025 (legal entity remains C2CA Technology BV), the company has since expanded partnerships, including EU-funded DETOCS and Ukraine reconstruction efforts.[2]
Everox stands out in concrete recycling through its patented, precision-engineered upcycling process, which outperforms traditional downcycling by producing high-purity outputs without water or chemicals:[1][3][4]
Everox rides the global push for circular construction amid escalating concrete demand (4.1 billion tons cement/year) and waste (3 billion tons discarded), fueled by EU and Dutch policies targeting 50-100% circularity by 2050 and CO2 reductions.[1][3][4] Timing aligns with post-war building demolitions creating rubble supply, while regulations like the Dutch Climate Envelope drive demand for verified low-carbon materials.[1] Market forces favoring it include investor interest in cleantech (e.g., PI Impact, Taaleri), EU funding, and partnerships with majors like Dura Vermeer and Sika's ecosystem, positioning Everox to influence the shift from virgin materials to localized, zero-waste loops—potentially cutting 2% of global CO2 while enabling profitable fines recovery.[3][6][7] It exemplifies the "next frontier" of cement innovation, complementing AI mix optimization and CO2-storing recoveries to decarbonize 8% of emissions.[7]
Everox is poised for rapid scale with its 2025 flagship factory operational, targeting global leadership in waste concrete upcycling by 2030 through expanded EU partnerships and commercial factories.[1][3] Trends like stricter emissions regs, circular economy mandates, and co-located recycling hubs will accelerate adoption, especially in Europe and emerging markets.[4][7] Influence may evolve via tech licensing, international pilots (e.g., Ukraine), and SCM integration, potentially disrupting virgin supply chains and yielding 2% global CO2 savings—transforming waste from liability to foundation for sustainable infrastructure.[2][3]
