How is CO2 Produced?
CO2 is produced by all aerobic organisms when they metabolize carbohydrates and lipids to produce energy by respiration.
In the process for bioethanol production, CO2 is produced during the process of fermentation of sugars in beer.
The plant of Vertex Bioenergy France in Lacq, supplies the carbon dioxide it produces for multiple applications (beverage carbonation, cooling and freezing), thus replacing CO2 from petrochemical units. Likewise, Biocarburantes de Castilla y León and Ecocarburantes Españoles, in Spain are capturing part of the CO2 gas that is produced during the biomass fermentations process.
