German family offices co-invest with EQT impact fund in mobile filtration provider

Swedish global investor EQT has acquired a majority stake in Belgium-based Desotec to expand use of its mobile filtration system to remove PFAS “forever chemicals,” along with hydrogen sulfide and other pollutants, from air, water and soil.

Germany’s family offices Athos and Merckle co-invested alongside EQT, which made the acquisition through its €3 billion EQT Future Fund. Desotec’s “filtration as a service” model system cuts waste by recycling carbon filters and destroying captured pollutants for its industrial customers.

“Desotec combines an attractive business model with measurable environmental impact,” said EQT’s Andreas Aschenbrenner. EQT acquired Desotec from private equity funds managed by Blackstone, which will remain a minority investor in the business.
