Plant example for dairy farms

Charchigné biogas plant:

• 237.000 MMBTU p.a. (3.6 MWel)
• More than 110,000 metric tons per year of cattle manure are processed
• Supplied by more than 110 farmers
• Electricity produced can supply approx. 8,500 households

Project timeline:

• Feb 2018: Start of earth works
• 17 months construction time
• July 2019: first gas production
• September 2019: CHP start (2x 1.800 kW)

This plant is mainly fed by manure from dairy farms surrounding the plant. The dry matter of the manure lies between 17 – 25% and contains significant amounts of stover.

Due to our effective pre-treatment before going into the digester and the optimized mixing technology inside, our Biogest PowerRing represents the perfect solution for solid manure including stover. For dairies with liquid slurry, it is possible to mix this substrate with stover inside the digester as well to boost the gas production.

With the PowerRing digester you make sure to get as much gas as possible out of your substrate before putting it into a (covered) lagoon.
