In Gråsten in southern Denmark, local farmers jointly operate a wet digestion plant converting agricultural residues from arable and livestock farming and biogenic waste from local industry into biogas. In 2022, it was expanded to include a membrane gas upgrading system from Kanadevia Inova.
The upgrade strengthens energy independence and supports Denmark’s climate neutrality target for 2045.

Solution
The plant upgrades biogas to biomethane using a Model M membrane system that reliably processes almost 1,000 Nm³/h of raw gas despite fluctuations in feedstock composition. Agricultural residues, deep litter, slurry, pig manure and biogenic industrial waste are converted into renewable gas, producing around 500 Nm³/h of biomethane for injection into the local gas grid.
A plug-and-play CO₂ liquefaction system can be retrofitted to capture, liquefy and market the CO₂ from the gas upgrading process.
