MD Biogaz Inaugurates Innovative CO2 Liquefaction Unit in France

MD Biogaz, a pioneer in the production of green gas in the Grand Est region of France, has inaugurated its biogenic CO₂ liquefaction unit which recovers biogenic CO₂ from biogas. The inauguration of ‘MD CO₂‘ took place at their methanisation site in Bar-sur-Seine in Aube on 24 June 2024.

The MD Biogaz site produces biomethane from agricultural and agri-food organic waste. This renewable gas is then injected into the natural gas grid, contributing to the reduction of greenhouse gas emissions. Biogenic CO₂, which comes from the anaerobic digestion process, is usually released into the atmosphere.

Thanks to an innovative biogenic CO2 liquefaction technology, provided by Tecno Project Industriale (TPI) and installed by Clarke Energy, MD CO₂ is now able to capture and reuse this precious gas resource. 100% of the biogas produced is recycled and the liquefier captures 4,000 tonnes of biogenic CO₂ per year, which is then purified and marketed.

The biogenic CO₂ from the MD CO₂ unit has multiple applications in the food industry. It can be used by brewers for the carbonation of their beers, but also in solid form, such as dry ice for industrial cleaning or the transport of vaccines. The inauguration of the MD Biogaz site and the presentation of the biogenic CO₂ liquefier illustrate the dynamism and innovation of the green gas sector in France.

These innovative technologies significantly contribute to reducing the carbon footprint and enhancing the recovery of organic waste in France.
