Voices from our partners
Real stories from the people who make the green gas generation possible. From farms to industrial plants, they show how biomethane powers the energy transition, creating tangible benefits for communities, businesses, and the planet.
Jan de Greef (Netherlands)
Jan de Greef’s farm proves how circular farming and clean energy go hand in hand. By processing local manure and food residues, his plant produces biogas, electricity, and biomethane for 1,600 households — while also creating valuable fertiliser products.
Thorsø Biogas Plant (Denmark)
One of Denmark’s pioneering plants, Thorsø has been evolving since 1994. Today it treats over 170,000 tons of biomass a year, delivering renewable gas to the grid and free heat to a nearby city — and preparing to expand further with CO₂ capture and new reactor capacity.
Dairy Farm, Jan Dirk (Netherlands)
In Friesland, home of Dutch dairy, Jan Dirk’s 300-cow farm produces both milk and green energy. After adding solar panels in 2010, he built a digester to create biomethane—a perfect complement to farming. Today, his gas is exported to Switzerland, proving how tradition and innovation can go hand in hand.
SFP Zeeland (Netherlands)
SFP Zeeland is a fast-growing biomethane producer combining innovation with scale. Using five digesters and a membrane system, the company turns manure and food waste into clean gas for heating and transport.
