Swiss Wastewater Association Tenders Biomethane Upgrading Facility with Biogenic CO2 Recovery

The intermunicipal wastewater association EBBV (Basse-Broye/Vully) in Switzerland has launched a public tender for a complete biogas upgrading facility. The plant will process biogas from the digestion of sewage sludge at its wastewater treatment operations and inject the resulting biomethane into the Swiss gas distribution network. The buyer aims to stop using its biogas only as a by-product and instead deliver renewable gas to the grid. This follows a wider Swiss trend of moving biogas assets from electricity generation to direct grid injection. No lots are mentioned.

The scope described includes membrane-based biogas upgrading and the grid-injection infrastructure. The tender also contains a mandatory option to recover, purify and liquefy the biogenic CO2 stream that is separated during upgrading. The captured CO2 could then be used industrially or as food-grade CO2 rather than vented. The work therefore touches on membrane separation, gas purification, CO2 liquefaction and thermal integration.
