Swiss start-up Sixteen44 takes methane removal tech from lab to farm – betting on real-world performance

Swiss start-up Sixteen44 is piloting its methane removal technology on a Swiss farm, aiming to prove it can eliminate diffuse methane emissions from cattle without interfering with the animals. The company’s system targets low-concentration methane in indoor livestock environments, converting it into water vapor and CO₂, and claims a 97% reduction in warming impact. The pilot will test real-world performance, with results independently validated and designed to support both carbon credit generation and compliance with tightening emissions rules. Sixteen44, founded in 2025, is targeting the removal of one million tonnes of methane by 2035 as part of its commercial strategy.
