Biogenic CO2
Bigadan transforms excess CO2 from biomethane production into a valuable resource, capturing and supplying it sustainably to various sectors.
Enhancing circularity
When upgrading biogas to biomethane, carbon dioxide is separated from methane. Traditionally, this CO2 was simply released into the atmosphere. There's a growing shift towards capturing and purifying this CO2 for reuse. Two primary applications exist: "Carbon Capture and Utilization" (CCU) and "Carbon Capture and Storage" (CCS). With CCS, the captured CO2 is stored underground, while CCU repurposes it for various industrial applications.
We already capture and liquefy CO2, removing impurities like sulfide and ammonia. Once pressurized, the gas becomes liquid, facilitating easier storage and transportation. This makes it usable for a long range of industries including food and beverage, electronics or in water treatment.
In the food and beverage industry, Biogenic CO2 can be used to carbonate drinks or keep products cold, while they are being transported.
Exploring new use cases: Power-to-X
We’re constantly trying to break new ground with our products. A new and intriguing application of captured CO2 is within the realm of Power-to-X processes. PtX refers to a set of technologies that convert electricity into new products, such as methane, hydrogen, and ammonia.
In relation to biogas plants, there’s a prominent opportunity to employ CO2 in a PtX process known as methanation. In this process, hydrogen is produced using electricity, and this hydrogen is then combined with CO2 to transform it into methane — enabling it to be used as fuel, e.g. in maritime transportation.
A gas with many applications
Sustainable Alternative
Biogenic CO2 offers a renewable alternative to fossil-derived CO2, reducing the carbon footprint of industries.
Various applications
Being applicable in a long range of industries from food and beverage to consumer electronics, we’re just starting to see the potential of biogenic CO2.
Potential for innovation
From Power-to-X processes (like metanization) to the production of commodities like methanol, biogenic CO2 has wide-ranging new industrial applications.
Carbon credits
Working with biogenic CO2 makes your green contribution quantifiable through carbon dioxide certificates that can be traded and used for offsetting.
Carbon Dioxide Certificates
ContactOur team of advisors can assist in exploring your possibilities with the realm of carbon dioxide certificates, carbon credits and offsetting. Typically, one certificate is equivalent to the offset of one metric ton of CO2. By purchasing or trading these certificates, you are effectively working on reducing your own footprint.

When food waste becomes refrigeration
As the first in Denmark, Bigadan produces liquid bio-CO2 by capturing, refining, and liquefying the CO2 generated during biogas production. In partnership with Nippon Gases, this liquid CO2 fuels the refrigeration units of leading retail chain, REMA 1000's, delivery trucks.
Our range of biogenic CO2 options
We capture and liquefy our own CO2 that’s seperated from methane, when upgrading biogas to biomethane. Instead of venting this CO2 into the atmosphere, it's captured, purified, and converted into a liquid state through pressurization. This liquid CO2 is both a food-grade and technical product.
Carbon dioxide certificates, or carbon credits, provide a tangible representation of greenhouse gas emission reductions. As biogenic CO2 is sustainably captured from our facilities, it aids in the generation of these certificates. We help companies move forward within this field, allowing them to offset their carbon footprint.
Biogenic CO2 can be solidified to produce dry ice, a valuable and sustainable resource used for cooling and refrigeration in various sectors. In collaboration with close partners, we can supply this product, e.g. for cases where electrical refrigeration is impractical, like during the transportation of perishable goods.
CO2 is essential for plant growth. Biogenic CO2 can be used to enhance growth rates in controlled environments such as greenhouses. By supplying plants with a consistent and pure source of CO2, crop yields can improve, meeting the demand of both local and commercial agriculture sustainably.
“The potential of capturing, storing and using CO2 in circular ways is so huge, that we see it as a given to explore it. Along with our partners, we’ll continue to push the limits for what’s possible”
