One use of vinasse is in thermophilic digesters. Vinasse produced from sugar cane is also called dunder. Treated vinasse is originated by a decantation and filtration process. For each unit of volume of ethanol, about eight units of vinasse are produced. In Europe, waste liquors from alcohol distillation are referred to as vinasse. Vinasse is a byproduct of the sugar or ethanol industry. The final byproduct, vinasse, is used as fertilizer or growth substrate for yeast cultures. Furthermore, vinasse is sometimes mishandled in storage and transport in mills. Vinasse can be used as a basal medium for "Haematococcus pluvialis" culture. Vinasse is sold after a partial dehydration and usually has a viscosity comparable to molasses.
