Rise Reforming

We turn waste gases into valuable supply-secure chemicals

About Rise Reforming

Geopolitical conflicts and natural disasters frequently expose the vulnerability of the American chemical industry. The reason? Production is centralized and fossil fuel-dependent. The solution? Localized production using an undervalued resource: biogas. The US produces enough biogas to make over $20 bn/y worth of chemicals, but 60% is wasted in low-margin applications or flared altogether. Rise Reforming is commercializing a modular process to transform this underutilized biogas on-site into cheap, supply-secure chemicals. Our beachhead market is dimethyl ether (DME), used as an aerosol propellant and a low-carbon fuel additive in propane. Our target market is methanol: an established billion $ chemical and the future of low-carbon shipping. We're doing our pilot project at a Chicagoland wastewater plant. This will be the first wastewater biogas-to-methanol demo in the Americas. We're hiring for a senior chemical process engineer.
