Cement-free & Circular.

At Oxara, we turn construction waste into sustainable building materials. Our innovative binder systems offer a cement-free alternative that reduces CO₂ emissions, promotes circular economy, and makes use of locally available (waste) resources. Discover how our technology transforms waste into value — and helps shaping the future of construction.

Oxara binder systems

At the core of all Oxara binder systems are mineral-based waste streams like clay-rich excavation material or mixed demolition waste. These locally available resources are combined with a mineral salt-based activator, resulting in a cement-free solution that enables material circularity, lowers embodied CO₂, and valorizes construction waste — all without relying on Portland cement.

Building materials based on Oxara’s binders

Oxara’s binder systems are designed to replace cement in concrete-like applications. When mixed with sand, aggregates, and water — just like traditional concrete — they form a strong and durable material. Oxara’s technology enables the production of cement-free building materials, such as poured earth or demolition waste-based concrete, adapted to local resources and specific use cases. Best of all, the binders are compatible with conventional concrete production infrastructure, making it easy for industry partners to switch without changing their processes.

Application Possibilities

Building materials based on Oxara’s technology are suitable for a wide range of applications — including lean concrete, flooring systems (such as screeds and terrazzo), internal walls, and composite systems in combination with wood.
