The CO2 that is separated during biogas upgrading with our LP Cooab or membrane system is pure and can be reused. Applications for this are for example:
• Greenhouse horticulture
• Cooling Refrigerant
• Food and beverage industry
• Dry ice production and blasting
With a simple purification step, the CO2 can be used in gaseous form in nearby greenhouses to increase the growth of plants and product. If the CO2 has to be transported over a greater distance, compression and liquefaction of the CO2 is necessary after treatment.
The liquid CO2 complies with the European Standard EU 231/2012 definition E290 for food quality.
