ENGIE invests in TreaTech, a startup that uses hydrothermal gasification to produce biogas

ENGIE New Ventures, ENGIE’s Research and Innovation investment fund for innovative startups that accelerate the energy transition, has invested in TreaTech. 

Founded in 2015 in Lausanne, the Swiss startup produces renewable gas using hydrothermal gasification to treat industrial liquid waste and municipal wastewater.

TreaTech raised €9 million from the financing round led by ENGIE New Ventures, Montrose Environmental Group and EIC Fund, and followed by CMA CGM1, Sipchem and Holdigaz. The funding will accelerate the industrialisation of its technology.

TreaTech’s technology was created at the Sustainable and Catalytic Processes Laboratory of the Ecole Polytechnique Fédérale de Lausanne (EPFL), in combination with hydrothermal gasification techniques developed by the Institut Paul Scherrer de Villigen (PSI). It is used to transform industrial liquid organic waste and municipal wastewater into biogas.

The technology has competitive benefits: a rapid reaction time (just a few minutes compared to several dozen days for anaerobic digestion); it uses little space; it can eliminate bacteria, viruses and pathogens; and it can treat plastic micro-particles (including PFAS, these so-called “forever chemicals”).

This investment in TreaTech forms part of ENGIE’s strategy to develop renewable gas in addition to anaerobic digestion, by increasing its biomethane production capacity in Europe to 10 TWh per year by 2030.
