Method for using vinasse

Abstract

In order to thoroughly solve existing vinasse problems, in particular in production of bioethanol from plant raw materials, a method is proposed for producing feedstuffs from crustaceans of the genus Artemia (brine shrimp) or Copepoda (oar-footed crustaceans) or Daphnia (water fleas) or from microbes in the form of rotifers or protozoa, the method being characterized in that the crustacean/microbe cultures are fed at least partially with vinasse, preferably thin vinasse, in particular from bioethanol production, and with yeasts contained in the vinasse. At the same time, a method for processing vinasse is provided, the method accordingly being characterized in that the vinasse is used as feed for crustacean/microbe cultures and/or for algae cultures in order to at least partially decompose the yeasts contained in the vinasse. In connection with this, it is also proposed that process heat produced during vinasse production, in particular in the course of producing bioethanol, is used to heat water for the cultivation of crustaceans/microbes and/or algae in order to use the thermal energy content of the vinasse in a useful manner.
