Technology & Products
Key Products
["CleanCast (Poured earth technology for floors and non-structural walls)","CleanPrint (Sustainable 3D concrete printing material using excavation waste)","CleanBlock (Compressed earth blocks/bricks for circular construction)","Oxara Admixtures (Proprietary chemical additives that enable earth-based materials to flow and harden)"]
Technological Advantage
Patented chemical binder technology that transforms soil into a liquid state for easy pouring (like concrete) and then hardens it quickly, maintaining structural integrity while eliminating the carbon footprint of cement.
Differentiation
Value Proposition
Decarbonizes the construction industry by replacing carbon-intensive cement with local excavation waste, reducing CO2 emissions by up to 90% and significantly lowering material and disposal costs.
How They Differentiate
Oxara differentiates by utilizing clay-rich excavation waste—a massive, underutilized waste stream—to create cement-free, non-fired building materials. Unlike competitors who focus on CO2 injection or industrial byproducts like slag, Oxara's patented mineral binder technology allows for circular construction using local soil.
