In our process of bioethanol production, CO2 is produced due to fermentation of sugars. By capturing the CO2, we can replace CO2 from fossil sources and improve the carbon footprint of our main product: ethanol. We capture this CO2 gas and thus reduce the emissions of greenhouse gas (GHG) improving, therefore, the sustainability of our facilities and final products. Our CO2 has the characteristics of food/beverage grade CO2.
The so-called DDGS (Dried Distillers Grains with Solubles) are the cereal byproduct of our distillation process. This high protein animal feed is known to increase efficiency and to lower the risk of subacute acidosis for animals. DDGS does not contain any sugars anymore, since these are turned into alcohol, and therefore reduces the enteric emissions (methane gas) from ruminants.
It replaces imports of genetically modified soya from North and South America.
We have installed gas turbines in order to combine the production of steam, needed in the process for cooking and distillation, and electricity, which we partly use ourselves, and partly reinject on the public network. By doing so, instead of using separate sources of electricity and heat, we save 30% natural gas consumption.
