Liquid protein


Sustainable production

BioWanze, the next-generation ethanol plant in Wanze, Belgium, extracts the liquid animal feed ProtiWanze® from the proteins and other components of the fermented wheat grain remaining after distillation. All raw material components are utilised. This feed is known as CDS (Concentrated Distillers' Solubles). The production diagram of BioWanze shows the manufacturing process of this feed.

Marketing for cattle and pigs

CDS is a valuable liquid feed for cattle and pigs with a high protein content. This product is marketed jointly with our distribution partners.

The location of the ethanol plant in Wanze, which is ideally situated on the Meuse from a logistical point of view, offers the possibility of distributing ProtiWanze® in the BENELUX market and the neighbouring German and French markets for liquid animal feed. ProtiWanze® is transported both by tanker to local markets in the vicinity of the production plant and by inland waterway vessel to more distant sales markets.
