Asahi Kasei Achieves High-Purity Biomethane from Waste

Diversified global manufacturer Asahi Kasei has successfully completed a demonstration trial of an innovative biogas purification system using zeolites in Kurashiki, Okayama Prefecture, Japan. Begun in February 2025, the trial achieved biomethane production with yield of up to 99.5% or more and purity of 97% or more. With such exceptional performance in both yield and purity, the system holds promise for the cost-effective production and utilization of biogas and biomethane across industries. Targeting commercialization in 2027, Asahi Kasei has launched full-fledged activity to license the technology to partners worldwide. As the use of renewable energy accelerates around the world, biomethane derived from biogas is attracting attention as a sustainable energy source. As of November 2024, 159 countries have signed the Global Methane Pledge, affirming their commitment to reducing methane emissions.…
