The WaterProof initiative is developing a process to capture CO2 from urban waste incineration and wastewater treatment, converting it into formic acid. This electrochemical process utilizes renewable electricity, aiming to reduce reliance on fossil feedstocks and create a circular economy model.
The captured CO2 is being tested for use in eco-friendly cleaning products and in partnership with Nordic Fish Leather for sustainable leather production. A large-scale pilot unit is planned for summer 2026 to facilitate commercial implementation.
Additionally, researchers are exploring the recovery of valuable metals from waste using formic acid-based solvents, although economic challenges persist. The initiative aligns with upcoming EU regulations aimed at enhancing material recycling and circular production.
