<h1>Multinational installs local membrane biogas upgrader at municipal waste digestion site, boosting biomethane purity, compliance, circular-economy goals</h1> A multinational energy firm commissioned a locally designed and manufactured membrane-based biogas upgrading facility at a municipal solid-waste anaerobic digestion site operated by a local waste management company, replacing a PSA unit and producing biomethane with >97% methane purity and reduced fugitive losses. The project supports a national bio-CNG initiative and leverages local supply chains, potentially easing permitting and procurement compliance while advancing circular-economy and clean-fuel policy objectives. Key legal considerations include environmental permitting, grid/transport fuel certification, performance guarantees, procurement/local content requirements, and long-term O&M and liability allocations.
