BioChipper has been designed to help maximise the potential of straw as a feedstock for Anaerobic Digestion.

Launched in the UK at the Cereals 2013 show the BioChipper has been designed and manufactured by our colleagues at BioG GmbH to help maximise the potential of straw as a feedstock for Anaerobic Digestion.

The result of 2 years of R&D the BioChipper’s purpose is to collect, process and swath straw products from agricultural processes to be utilised as a feedstock to AD plants. The BioChipper has a series of mulching hammers to pre-process straws such as oilseed rape, bean and grain maize straw.

The benefit of the BioChipper is that it allows a low cost feedstock to be collected from the field without soil contamination as it does not touch the floor.

By mulching the straw and swathing prior to collection allows the AD plant to overcome the high lignin properties of the straw.BioG Austria currently have an AD plant fed on 20% straw from crop residues so further increasing efficiency and sustainability

The BioChipper developed by BioG, a mulch concept with swath consolidation enables the harvesting of field residues such as corn straw, rapeseed straw, grain straw, catch crops and landscaping materials. The operations of suctioning, chopping and swathing are carried out in a single step.

The BioChipper combines the organic matter into a swath and enables its harvesting by a loader wagon or shredder. This allows for an efficient use of field residues. In addition to the removal of field residues, positive side effects such as active pest reduction, reduced fungal contamination of the succeeding crops and better nutrient management are also achieved.

The BioChipper is available from 3 to 6 meters, so that a swath distance of up to 12 meters can be achieved when driving on the opposite side.


  • Can be used after each harvesting
  • Low degree of contamination
  • Material pick-up without ground contact
  • Stubble reduction
  • Only one drive necessary
  • Easy transport with a pick-up
