CO2 Summit: Oxylum stands ready with decentralised CO2-to-formic acid tech

Belgium-based technology start-up Oxylum plans to tap into Europe’s rapidly growing biomethane sector by converting waste CO2 into formic acid, which is a valuable chemical feedstock. It will need partners as it scales, but is clear on the market potential.

Speaking at gasworld’s European CO2 Summit 2025 in Rotterdam, Oxylum CEO and co-founder Bert De Mot highlighted a significant, untapped opportunity to utilise purified CO2 from biomethane and biogas plants. Today many of these currently vent the gas as a waste stream for a a lack of suitable infrastructure.

“These facilities don’t have utilities or the pipeline network that we in the chemical or metal industries are used to,” De Mot explained. “They have no other option than to throw the CO2 into the air.”
