Problem
Traditional concrete production relies heavily on cement, a major contributor to global CO2 emissions, and often requires the extraction of virgin resources, exacerbating environmental degradation. The construction industry also faces challenges in managing and repurposing construction and demolition waste, leading to landfill overflow and resource depletion.
Solution
Oxara provides a suite of cement-free admixture technologies that transform mineral construction waste and excavation materials into sustainable building materials. Their solutions, including Oxacrete Oulesse, Oxacrete Care, Oxacrete Nossim and Oxabrick Loko, eliminate the need for traditional cement, significantly reducing embodied carbon emissions by up to 74% and promoting a circular economy. These admixtures enable the reuse of demolition waste and excavation material, turning them into valuable resources for creating concrete, blocks, and other construction elements. Oxara's technology allows for the use of existing concrete infrastructure for production, transportation, and processing, making it easy to integrate into current construction practices.
Target Audience
Oxara's primary customers include construction companies, real estate developers, and government entities seeking sustainable and cost-effective building materials to reduce their environmental impact and promote circular construction practices.
