Since 2008, Sachsenmilch Leppersdorf GmbH has been operating a plant for the production of bio-ethanol from the residual whey product molasses, which produces 10 million litres of the biofuel additive annually. With this plant - an investment of around 20 million euros - the Unternehmensgruppe Theo Müller took on a pioneering role throughout Germany.
The production of bio-ethanol from the so-called molasses, the partially desugared permeate produced during lactose production, was a completely new process in 2008. With this innovation, the engineers of the Unternehmensgruppe Theo Müller have found an alternative to the production of fuel from biomass, i.e. without land use.
The production process of bio-ethanol is simple and efficient: cheese production produces whey from which protein and lactose are separated. Until now, the remaining molasses has been used or disposed of as a feed additive. In the bio-ethanol plant, this by-product is fermented by adding yeast to alcohol and separated from water and minerals in a distillation plant. Ultimately, 99.8 percent pure bio-ethanol is produced, which can be used as fuel without further treatment. The entire process is subject to the highest safety regulations and, of course, strict separation from food production.
This innovation was also a further step towards making full use of the valuable raw material milk.
Unternehmensgruppe Theo Müller regards its retail customers as partners and therefore supports them not only with branded articles, but also private label products as required.
