everox unveils game-changing technology to transform concrete waste into sustainable building materials

Rotterdam, Netherlands – September 10, 2025 – everox, a pioneer in sustainable construction solutions, has announced the launch of its patented technology that upcycles concrete waste into high-quality substitutes for cement, sand, and aggregates. This innovative process significantly reduces CO₂ emissions and landfill waste, offering a practical step towards solving the construction industry’s biggest environmental challenges. As the cement industry is responsible for around eight percent of global CO₂ emissions, replacing cement with effective substitutes is key to addressing this problem.

everox stands out in the market by offering a full end-to-end solution, producing drop-in substitutes for primary products made from concrete waste. The technology is highly adaptable and capable of processing variable qualities of concrete waste. It reduces CO₂ emissions by more than 90 percent compared to traditional cement production while producing high-quality output products with low energy use and minimal waste, ensuring both environmental and economic sustainability.

The patented everox process combines advanced crushing, separation, and activation technologies to recover all valuable components of waste concrete and turn them into four high-quality products:

• Activated Cement Paste
• Recycled Coarse Aggregates
• Recycled Fine Aggregates
• Fine Inert Filler

The game-changer is the upcycling of the cement paste, which is traditionally lost in recycling. Reactivating the cement paste makes it reusable for the first time, enabling it to replace a significant portion of virgin cement.

The compact, energy-efficient upcycling plants can be installed permanently to supply regions with sustainable building materials or deployed temporarily in areas where infrastructure has been severely damaged by natural disasters or human impact. This flexibility creates independence from global supply chains, provides rapid access to new building materials, and significantly reduces the carbon footprint of reconstruction efforts.

Global concrete waste is estimated to exceed 3.5 billion tons annually, underscoring the vast opportunity for everox technology to cut emissions. To capture this potential, the company is partnering with construction, recycling and concrete manufacturing firms worldwide on scaling the production of sustainable building materials.

First sustainable real-life projects as proof of concept have been executed, such as the living lab study at South Pier Ijmuiden. There in total 11 concrete blocks, made of upcycled everox material are exposed to wind and water as part of a long-term material study. The first testing results demonstrated a compressive strength of 52.3 MPa after 28 days. This performance surpasses expectations and meets the demanding C40/50 strength class.

Since 2022, everox has successfully processed over 1,000 tons of waste concrete at its pilot plant in Hoorn, Netherlands, demonstrating scalability and effectiveness.

Looking ahead, the company’s joint venture with the Rotterdam-based construction company Dura Vermeer is working on the first fully commercial-scale flagship plant in ’s-Gravendeel, Netherlands. Opening in 2026, the plant will process 150,000 tons of waste concrete annually, supplying premium recycled aggregates and a cementitious binder to the market and driving a circular economy for concrete in the Netherlands. Further collaborations in high-potential markets are planned as the next step in the company’s development. With a focus on other European countries, the UK, and North America, everox plans to implement seven additional flagship plants in the next three years.
