Conclusion: - ongoing learning
• Cheap carbon sources; identify feedstocks on location – regional.
- But it have to be cheap and sustaiable!
• Manure of any kind; including solid manure types
• Straw and lignocellulosic byproducts incl. bagasse (Brazil!)
• Grassland products from nature, extensive & intensiv farming
• Organic food waste and organic wasted byproducts
• Industrial organic waste streams and byproducts. Recycling
• Aquatic algaes macro/micro & byproducts (have to be
developed

Nature Energy – Biogas PlantsBiogas is becoming a central part of the Renewable Energy supply mix in the future. NFG-Holsted biogas plant
is supplyed with sustanable biomasses from local animal farming units, cheap carbon sources like deep litter as
well as food waste. The large volume of produced biogas is further processed, cleaned, upgraded and injected
into the national Danish Gas-grid. Read more at www.natureenergy.dk;
NFG- Nature Energy
ltd. is the biggest
biogas constuction
and owner company
in Denmark
26
THE KORSKRO CASE
• 710.000 tons of biomass per. Year
• Currently the biggest in DK and EU
• 85% residues from agriculture
• Cattle Manure
• Pig Manure
• Mink Manure
• 15% Municipal and Industrial Residues
• MSW
• Slaughterhouse Waste
• Deep litter from husbandries
• 7 x 9000m3 Reactor Tanks
• Gas Cleaning and Upgrading Systems
• Highly Automated
• 22 mio. m3 biomethane per. Year
• 100 farmers in the supplier association

•Biogas has been taken to next level•6,000 Nm3 biogas plant•48 tpd CO2 recovery
•Upgrading both Methane and CO2
is an environmental gain:• Methane can be utilized on gas grid• CO2 can be utilized for different
purposes:• Food grade• Green houses• Fire fighting• Welding
New reliable sources arisesBiogas case: Strandmøllen/Korskro29

• Per 1.000 Nm3 biogas =>
• Normal split: 60% Methane + 40 % CO2
• 40% CO2 = approx. 800 kg/h CO2
• Petrol car emission factor 0,1185 CO2/km (https://www.transportenvironment.org/what-we-do/cars-and-co2)
• The CO2 emission from 1.000 Nm3 biogas is equal to a driving distance
of 6.750 km each and every hour in a modern cars
