Brimex Energy’s renewable natural gas plant is the first renewable thermal project in Mexico to included on North America’s largest clean energy registry.
Brimex Energy’s facility in Lagos de Moreno, Jalisco, converts organic waste, including tequila by-products, into renewable energy. The registration allows Brimex to generate renewable thermal certificates (RTCs) through the CleanCounts Registry, operated by non-profit CleanCounts.
An independent review by EcoEngineers in 2025 confirmed the claims.
Dairy and tequila waste
Three anaerobic digesters at the Brimex facility process organic waste from several industries. Feedstocks include milk byproducts, pig manure, wastewater sludge and vinasse from tequila distillation.
The company sources material from businesses including tequila producers Teremana and Campo Azul. Food manufacturers Grupo Lala and Sigma Alimentos also supply the facility.
The resulting biogas powers generators that supply electricity to the commercial grid. Brimex also upgrades biogas into biomethane for vehicle fuel.
The company holds Mexico’s first federal permits for biomethane production. It obtained the commercialisation permit in February 2026.
Brimex ceo Guillermo Chaim Serrano says the registration adds another layer of value to the facility’s output. ‘We built this plant to prove that the waste streams of Los Altos could provide clean energy to the region.
‘This registration is the next step. Every dekatherm we produce now carries proof that buyers and auditors across North America recognise.’
Tracking renewable fuel
The CleanCounts Registry gives each certificate a unique serial number. Records include the energy resource, production location and generation period.
This system creates a traceable chain from renewable energy generation through to certificate retirement. It also aims to prevent two parties from claiming the same energy attribute.
CleanCounts says its software issues more than 40% of renewable energy certificates in North America. The registry issued its two billionth certificate in 2025.
CleanCounts president and ceo Ben Gerber describes registries as the accounting infrastructure supporting decarbonisation. ‘They make sure a dekatherm of Mexican biomethane is measured once, claimed once and trusted,’ he says.
Brimex’s registry account is held through Cyan Energy, which acts as account holder and certificate marketer.
