For the anaerobic digestion plant in Lana/Bolzano, which has been in operation since 2007, an expansion and modernization was decided in 2018. The design and implementation of the conversion by Finsterwalder Umwelttechnik into an innovative model plant was successfully completed in summer 2021. The expanded pretreatment system is scheduled to go into operation in 2022. A doubling of capacity is planned. At present, the Italian showcase plant has a treatment potential of 30,000 tons/year. 40 municipalities from the South Tyrolean region currently deliver their biowaste to Lana. The operators rely on Finsterwalder technology for the implementation of the anaerobic digestion plant and its expansion. Simplified treatment processes make it possible to reuse all organic substances of the biowaste and to optimize energy recovery.
