How long does it take to build a biogas plant?
For a moderate to large scale digester (300 m3 +) it will typically take, from the first call to a running biogas plant, anywhere from 8 months to 2 years. If you are interested in building a small family size digester (10 m3 or less) you can count about 1 to 2 months until you have a functioning biogas plant.
