Gas Engines
There are a total of 3 Engines, two utilizing condensated tar oil from Pyrolysis and one
fueled with biogas from anaerobic digestion. Every engine has his own generator attached,
and the tar oil fueled engines have outputs of 100 kW (see Figure C-66) and 60 kW (see
Figure C-67). The gas fueled engine has a output of 100 kW (see Figure C-68) as well.

There is an anaerobic digester installed for operation with sewage and biomass. The unit
was not under operation during the field visit. Next to it are concrete bricks aligned in a
rectangular manner, forming sludge drying beds where the sludge can be allowed to dry
under the sun. Several (ca. 10) shipping container are connected with a gas collection
system for dry fermentation to be carried out.
