CO2 collected through a biorefining process can be used for a number of different purposes.
Besides fiber, protein and bioethanol, the production procedures clean CO2, which can be collected and used in e.g. greenhouses to increase the airs amount of CO2, or in fizz for beer and soda. The product can also be used for industrial purposes.
Clean CO2 from biomass
As opposed to the CO2 normally used in greenhouse productions, this is a 100 % clean CO2, and because of this, there will be no need for cleaning the CO2. The CO2 is clean because it is produced on biomass, as opposed to productions based on non-renewable resources.
