Fermentation breaks all good things down into three parts

Fermentation is a very old technique. In our case we add the yeast to the grain (or other material) mixed with malt and water. The process takes about two days to form ethanol and carbon dioxide. The starch in the raw material is what is transformed into these two components. The first product is thus Ethanol, representing about one-third. Carbon dioxide is also about one-third, which we collect, liquify and turn into carbonic acid. The final third is the protein and fibres from the raw material that the yeast can't break down, known as "destillers’ dried grains and solubles". We produce a high-grade protein feed for livestock, mainly cattle and pigs, from the destillers’ dried grains and solubles.

Research and innovation for a greener future

Lantmännen Agroetanol is very active and a driving force for the rapid development of the Green Revolution. We are a leader in the field, and work consistently with other bodies in several areas of research, including the business community, universities and colleges.

Ultimately, techniques will be refined and prices will drop, enabling us to work with other raw materials and to be able to produce other products from our ethanol and our protein. Bio-based plastics and various bio-based chemicals to replace fossil oil-based products are some examples. One thing we know for sure – Green will soon replace black!
