Pre-treatment for anaerobic digestion

 

 Input material:

  • Maize silage
  • Biowaste from agriculture
  • Wheat
  • Straw
  • Green waste (i.e. hops)

 

 Output material:

  • Open fiber material optimal for anaerobic digestion

 

 Features of output product:

  • Open fibers
  • Low density
  • Small particle size
  • High homogenity

 

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.
