Biomass processing
DAN-ETV offers verification of technologies and products for treatment of biomass for energy production from crops, and residues of industrial or agricultural origin for example pretreatment of biomass as a part of biogas production or production of fuels like bio-ethanol, bio-diesel or bio-oils. Verifications will include mechanical (separation, pressure, etc.), thermal (heating, cooking), chemical (acidification, alkali treatment etc.) and enzymatic treatments as single processes or in combination.

Completed verifications:
Pretreatment of maize
ensilage and fibers from separated
liquid cattle manure for biogas production
Test and verification of the Deflaker 200 from the
company Cellwood Machinery AB, Sweden, has been performed by Danish
Technological Institute.
The verification showed increased biogas
production from maize silage when treated mechanically with the
Deflaker prior to anaerobic fermentation.
Thermal/chemical pretreatment of
separated manure
Verification of thermal/chemical pretreatment (alkaline pressure cooking) of separated manure (dry fractions/fibers) and dry manure from poultry is conducted at a biogas plant and laboratory. The purpose of the treatment is to increase the biogas yield and to remove a part of the nitrogen from the substrate to avoid inhibition of the biogas process. The test
was conducted in cooperation with GFE Patent A/S (Green Farm Energy and Xergi A/S). The treatment is called NIX treatment.

Biogas yield of fibres from manure treated with sulphuric acid
A second verification of biogas potential is conducted on the dry fraction of acidified and separated swine manure. The test
was conducted in cooperation with Grundfos New Business A/S.
