Use of Rye as Bioethanol
In Germany a market for bioethanol has only existed since the year 2004 and it is still the largest ethanol market in the EU, followed by France and Spain. An EU directive on biofuels aims to increase the proportion of fuels from renewable raw materials up to 20 % in the year 2020. Bioethanol plants offer an alternative marketing opportunity for cereals. However, the raw material has to fulfill specific requirements: Cereals for ethanol production must contain mainly starch and less protein and cell wall components.
Cereals that are rich in starch, such as wheat, triticale and rye, are especially suitable for bioethanol production. In particular due to the limited cultivation alternatives on the light sandy soils of Brandenburg the use of rye as a bioethanol raw material is economically very interesting. In Schwedt, Brandenburg Verbio produces in the second largest German plant with an annual capacity of 200,000 tons bioethanol mainly from rye.
