Anaergia Inc. announced it has signed an agreement with European Energy A/S (European Energy). Under the terms of this agreement Anaergia is to supply European Energy with up to 60,000 tonnes per year of liquefied biogenic Carbon Dioxide (CO2) for a period of 10 years. Biogenic carbon dioxide is carbon dioxide that is released during the decomposition of organic matter such as food waste.

All Anaergia plants use organic waste material to produce biogas, which is composed of methane and carbon dioxide. Once this gas is processed, Anaergia produces pipeline quality Renewable Natural Gas and a clean stream of carbon dioxide that normally gets released to the atmosphere where it originally came from. Biogenic carbon dioxide that comes from organic material is considered a desirable raw material for low-carbon fuels as its use does not add new carbon to its atmosphere.

Anaergia will provide the liquified CO2 from the anaerobic digesters that will operate at its plant being built in Tønder, Denmark. Owing to this agreement with European Energy, Anaergia will build a CO2 liquification system at the plant.
