Launch HN: Rise Reforming (YC S26) – Turning Waste Gases into Valuable Chemicals

Rise Reforming, a Y Combinator S26 company, has developed a modular technology that converts waste biogas from wastewater plants, farms, and landfills into valuable chemicals like dimethyl ether, methanol, and dimethyl carbonate. The containerized system addresses supply chain vulnerabilities in chemical production by utilizing the $20 billion worth of biogas currently wasted annually in the U.S., while producing competitively-priced, low-carbon chemicals. The company has completed proof-of-concept testing and is now deploying its first pilot unit at a Chicago wastewater plant.
