CO2 valorization – Recovery and reuse of carbon dioxide
Reuse of CO₂ for industrial purposes
Biogas obtained through anaerobic digestion is usually composed of methane (CH₄ - 50 to 70%) and carbon dioxide (CO₂ - 30 to 45%). After its purification into biomethane, the gas that is usually released into the atmosphere (known as "waste gas") contains around 99% CO₂ and 1% CH₄.
V'COOL technology
The V'COOL plant liquefies the waste CO₂ and at the same time recovers the residual methane, which can be returned for reuse in the biogas plant. This process allows to significantly optimize efficiency and reduce methane losses.
Why is it important to reuse CO₂?
- Reduction of greenhouse gas emissions: CO₂ valorization allows to reduce harmful emissions into the atmosphere, contributing to environmental protection.
- Maximize purification efficiency: The capture of methane residues in the exhaust gas allows to increase the overall efficiency of the plant.
- Commercial opportunities: Bio-CO₂ can be sold to various industries such as agriculture, food processing, etc.
Green CO₂ applications
2. Food industry
Suitable for freezing and preserving products, carbonation of beverages and other food processing processes.
3. Materials and processing
Used for the assembly of metal parts, additives in filter production, as well as other technological processes.
4. Chemical industry
CO₂ is used in supercritical fluid extraction, cryogenic grinding, carbonate agent and chromatography.
5. Universal industrial processes
Suitable for cooling, use in laser technology, arc welding and other high-precision manufacturing processes.
6. Other areas of use
CO₂ can be used for dry ice fumigation, descaling, production of dry ice for fire extinguishers, and as a propellant in aerosols.
Thus, the valorization of CO₂ provides a significant economic and environmental effect, allowing its use in a wide range of industrial processes.
