Utilization and biodegradation of starch stillage (distillery wastewater)
Stillage (distillery wastewater) is the main by-product originating in
distilleries, and its volume is approximately 10 times that of ethanol
produced. It is not surprising that the utilization of the stillage
raises serious problems, and that many attempts have been made all over
the world to solve them. In Poland most of the ethanol (about 90%) is
produced from starch-based feedstocks, i.e. grains and potatoes. Starch
feedstocks are widely used for spirit production also in other European
countries, as well as outside Europe. The manuscript provides an
overview of global fuel ethanol production and information on methods
used for starch-based stillage biodegradation and utilization. The
methods presented in this paper have been classified into two major
groups. One of these includes the mode of utilizing starch stillage,
the other one comprises methods, both aerobic and anaerobic, by which
the stillage can be biodegraded
