Decarbonization and water technology startup Capture6 announced that it has raised $27.5 million in a Series A funding round, with proceeds aimed at advancing its projects converting water treatment brine into a carbon removal solution, while also recovering fresh water. Established in 2021, California and New Zealand-based Capture 6 offers a solution that simultaneously provides carbon removal and water treatment, and connects directly with existing water infrastructure. The company has developed a system that transforms waste brine, a byproduct of many water treatment and desalination methods that is expensive to dispose of, into a solvent that mineralizes CO2. This material can then be used to trap the carbon produced in the water treatment process.
