Utzenaich, AT

Best of Austria

The Utzenaich plant shows the value in flexibility concerning the digester’s ability to treat different types of feedstock. Designed as a slurry and silage plant, Utzenaich was soon facing rising prices of their main feedstock maize silage. Thanks to our polyvalent ring-in-ring technology, the adaption to a waste-based feedstock ratio was no problem. Today Utzenaich is solely producing its power with slurry and maize straw in summer and adding manure in winter.

Produced electricity is fed into the Austrian grid and the heat of the CHP is utilized to dry wood chips.
