Toray Industries, Inc. reported progress in a one-year trial of an all-carbon CO2 and methane separation membrane at a customer's biogas production facility in Osaka Prefecture, Japan. The technology reduces moisture removal costs by approximately 70% compared to existing systems.

Traditional membranes degrade in moisture, necessitating a costly drying step. Toray’s membrane eliminates this need and can also be applied to natural gas purification and CO2 capture from industrial emissions. The technology will be showcased at Nano Tech 2026 in Tokyo.
