The lignocellulose rich material as straw, wheat and maize silage are mechanically crushed into fibers through the Promeco Bioextruder ©, to increase their surface area accessible to the bacteria. This treatment is necessary before AD to destruct the lignocellulosic structure and to release sugar contained in the biomass.
Advantages of the treatment with Promeco Bioextruder
Increasing of the digestion of maize silage of over 40% (considering 12 days’ retention time). The study has been carried out by the University of Linköping, Sweden.
To produce 1 MWh power 18.000 ton/year of extruded maize silage are needed instead of 25.000 ton/year of unextruded material.
