Farms generate vast quantities of manure, which, as it ferments, releases methane – a greenhouse gas 28 times more potent than carbon dioxide. With on-farm biogas plants, the fermentation process is carefully controlled, and the resulting methane is collected and piped to a cogeneration plant to produce both heat and electricity.
BCV provides financial support to two biogas facilities located in the Canton of Vaud: EnerBroye and BGA Martin. The EnerBroye facility supplies the Vaud grid with 6.7 million kilowatt-hours (kWh) of electricity annually, enough to power around 1,700 households for a year. Around 4,7 million kWh of residual heat per year is used in nearby factories and to sanitize food waste. The second facility, BGA Martin, generates 1.3 million kWh of electricity and 360,000 kWh of residual heat per year.
These projects, which are ISO 14064-2 certified, save around 4,400 tCO2e per year. Because on-farm biogas plants provide a year-round source of renewable energy, they help reduce the dependency of Swiss farmers on imported fossil fuels while actively supporting sustainable development in the region.
