Wiefferink Bag

Wiefferink produce manure bags, we had the idea of installing it in an insulated environment, making use of an underfloor heating system, which we deployed in the base and around the banks. We also added two agitators. The bag holds 5,000 m3 of digestate and 2,000 m3 of biogas.

The Combi-bag, as it is known, acts as a secondary digester in this plant and produces about 5,500 m3 of biogas per day.
