Biomass for energy purposes

DANETV provides verification of technologies and products for the use of biomass and residues for energy purposes. Verifications may include mechanical, thermal, chemical and enzymatic methods for biomass processing for increased energy output. Examples of technologies can be separation of cattle manure for biogas production, energy-efficient drying process of slurry fiber fractions.

The following test centers perform verification in this area.

Completed verifications:

Pretreatment and separation of organic waste from households and industry to obtain a pulp for biogasification
The verified mechanical process treats and separates mixtures of organic waste/plastic packaging/textiles/metals/glass etc. The process produces a pulp suitable for biogasification as well as a solid reject fraction of plastics, textiles, metal and glass. The verification was performed for the Danish company Komtek Miljø A/S.  Verification Statement, Verification Report and Test Report.

Separation of cattle slurry
Verification of slurry separator for cattle slurry. The verification includes a test of separation efficiency and measurement of electricity consumption. The separator is produced and sold by S.B. Engineering. Verification Statement, Verification Report and Test Report.

Post-treatment of digestate
Verification of a technology for post-treatment of digested biomass on a centralized biogas plant. It is a decanting centrifuge produced and sold by GEA Westfalia. The verification includes a test to determine the separation efficiency with respect to nitrogen and phosphorous. In addition the particle size distribution is determined in the liquid fraction leaving the centrifuge. Verification Statement, Verification Report and Test Report.

Energy efficient pre-treatment of biomass
Verification of an energy efficient technology for drying manure fiber fractions. For the drying process a steam drier is used. The technology was tested for the efficiency of the steam drier in relation to dry matter content of the manure fibers. The technology was verified for Cimbria Manufacturing A/S. Verification Statement and Verification Report incl. Test Report.

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. The Danish company AL2 agro distributes the Deflaker in Denmark.  Verification Statement, Verification Report and Test Report.

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. Verification Statement, Verification Report and Test Report.

Biogas yield of fibers 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. Verification Statement, Verification Report and Test Report.
