Toulouse Filtration Specialist KOB Seeks Investor to Boost Industrial Scale-Up Amid Circular Economy Push

KOB, a Toulouse-based firm specializing in innovative water filtration solutions within the circular economy, announced on April 29, 2026, that it is looking for a buyer or investor to accelerate its industrial development. The company, currently under judicial recovery, needs a partner capable of scaling its production to meet growing market demand and turn profitability. Despite promising market interest in its patented SANDBAG® filtration technology—which offers superior filtration and significant water savings by using waste glass in its manufacture—KOB's revenues are insufficient to cover the high costs of large-scale production. With a production capacity of up to 900 tons per year, the company has raised nearly one million euros from founders and partners for initial structuring and launch stages. Management emphasized that this opportunity suits investors or entrepreneurs seeking a mature, operational project with proven technology and growth potential in sectors such as international irrigation and industry. While the search for a buyer is ongoing with an expected conclusion within six weeks, KOB’s daily operations will continue as usual.

This development coincides with broader French efforts to promote circular economy initiatives as a sustainable response to inflation pressures affecting many sectors, including rising household costs. Consumers are increasingly embracing circular economy practices, such as donating and renting items, facilitated by apps like Geev and Poppins, which aim to reduce waste and foster sustainable consumption. Economist Louis Dupuy highlighted France's progress in this domain, supported by the ADEME agency, with the Nouvelle-Aquitaine region notably recycling a significant portion of its average 643 kg of waste per inhabitant annually.

KOB’s search for a strategic industrial partner represents a concrete industrial-scale example of circular economy principles transitioning from innovation to market viability amid France’s growing sustainability drive.
