EnviCO₂ – Food-grade CO₂ liquefaction
From waste to raw material: utilising CO2 efficiently and tapping into new revenue streams
Carbon dioxide is so much more than just an emission. Gaseous CO2, which is produced, for example, during the processing of biogas into biomethane, can be liquefied and used in a variety of ways as a valuable resource. With our EnviCO2 process, we offer a proven solution for liquefying biogenic CO2 to food-grade quality – for both new and existing plants. EnviCO2 enables CO2 to be processed directly at the biogas plant and marketed as a valuable, transportable raw material – simply economical, sustainable and future-proof.
Your benefits: At a glance
- Everything from a single source – planning, construction and integration by EnviTec
- Proven technology from our own operations
- Over 20 years of international experience in biogas and gas processing
- Compatible with various processing technologies
- Sustainable construction using climate-friendly refrigerants (CO2 / R744)
- Food-grade bio-LCO2
Our technology: on-site CO₂ liquefaction
Compression, cooling, condensation, purification: EnviCO2 technology is based on a multi-stage treatment and liquefaction process. In this process, the CO2 contained in the biogas is dried after purification and then liquefied.
The result: high-purity, food-grade bio-LCO2 – produced directly on-site, easy to transport and versatile in its applications.
Flexible and high-performance
Our EnviCO2 plants are as individual as your requirements: tailor-made to your needs, flexible in use.
- Variable: Capacity of approx. 200 to 5,000 kg LCO2 per hour
