Biogenic CO₂

CO₂ is unavoidable for many natural and technical applications. If it comes from fossil sources, however, it contributes to man-made climate change. CropEnergies has therefore been working for years on expanding the CO₂ circular economy, both for its own plants and as an important contribution to climate-friendly mobility and nutrition.

The raw materials used by CropEnergies absorb CO₂ from the atmosphere during growth. When converted into usable products such as neutral and fuel ethanol as well as food and animal feed, biogenic CO₂ is produced during the fermentation of the sugar, which can be captured, purified and put to further use. The purity of the carbon dioxide obtained meets the highest requirements of the food and pharmaceutical industries. Overall, CropEnergies is aiming for virtually complete use of natural raw materials.

CropEnergies already operates CO₂ recovery at two locations: in Zeitz, Saxony-Anhalt, and in Wilton, UK. In Wanze , Belgium, the recovery plant for the purification and liquefaction of biogenic CO₂ will come on stream in September 2021.
