Since 2012 the French Drouilhet family operates a Bert 600m3 digester and a CHP with 50 kW/h electrical output. Without adding other substrates, about 10,000 tons annually (= 27 tons per day) 100% pig slurry (DM 5.7%, ODM 77.1%) are processed by the digester. The pig farm with 450 breeding sows and 4,000 rearing places is housed in 4 buildings. With the Bert digestate 280 ha of corn and cereals are fertilized.
