The Mobile Feeding Unit (MFU), a complete modular feeding unit for solids, reduces construction time and minimises installation work on-site. In contrast to the conventional procedure, in which components are individually installed in the biogas plant, the MFU is preassembled at the Vogelsang facility, eliminating influences by the weather. After being tested at the factory, a fully deployable module is delivered and can quickly and easily be integrated at the plant.
