A single-stage biogas plant digests like a pig: maize yes, fibre hardly. Our two-stage system turns it into a cow. Two compact high-load digesters upstream of the main digester let your plant digest grass, straw, manure and other fibrous feedstocks \u2014 safely and profitably. Because biology decides whether a biogas plant works. Technology only makes it possible.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

An anaerobic digestion plant isn’t a chemical plant \u2014 it’s a living biological process. Treat it like a steel tank with pipework and you’ll pay for it later: foaming, acid crashes, too little gas. We think biology first and derive the technology from it. That’s exactly what makes your plant stable and profitable.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
