The ETH spin-off Oxara was founded in 2019 with the aim of drastically reducing CO₂ emissions, promoting the circular economy in the construction industry and enabling sustainable and affordable housing. The partnership between Oxara and KIBECO aims to combine resources and expertise to bring Cleancrete^®, a cement-free clay concrete, to the market by 2022.

Both companies are aware of the strain on resources and the millions of tons of waste generated by the construction industry every day. For example, in the form of excavated materials, which represent one of the largest waste streams. Oxara has developed a range of mineral-based admixtures that convert excavated material into cement-free clay concrete. Similar infrastructures and processes are used as in the production of conventional concrete.
