Bio-CO₂: A renewable resource for the industry of the future

During the upgrading of biogas to liquid biomethane, we capture pure carbon dioxide. This is not fossil CO₂, but biogen CO₂ which is already part of nature's natural cycle. By capturing and reusing this gas instead of releasing it, we close the carbon cycle and create a valuable, green raw material for industry.

From by-product to high-value raw material

Our capture of CO₂ takes place in connection with the purification of raw gas, and the result is a high-purity product that can replace fossil CO₂ in a number of sectors:

  • The food and drink industry: Used for carbonation in beverages, refrigeration, and as a protective atmosphere in food packaging for increased shelf life.

  • Greenhouses and agriculture: Addition of CO₂ in greenhouses increases plant photosynthesis and provides faster growth and better yields in a natural way.

  • Industrial refrigeration: An environmentally friendly alternative to synthetic refrigerants in large refrigeration systems and heat pumps.

  • Circular production: By utilising biogenic CO₂ from our facilities, industrial operators reduce their own environmental footprint by phasing out fossil sources.

Benefits of Bio-CO₂ from an Antec plant

By choosing biogenic CO₂, your company contributes to a more sustainable value chain:

  • Carbon-neutral solution Since the gas comes from biological material, it does not add new carbon to the atmosphere the way fossil CO₂ does.

  • High delivery precision: Our facilities ensure stable production and local access to CO₂, which reduces the need for long-distance transport.

  • Documented sustainability: We offer full traceability of the gas's origin, which strengthens your company's environmental reporting.

Nothing goes to waste: Bio-CO₂ capture is the final step in making biogas production 100 % circular. What was previously a by-product is now a key resource for a greener industry.
