  • a farmer growing energy crops can supply both the threshed grain and the straw (fresh cornhoppers).
  • the grain here for example triticale, with the highest possible starch and low protein content is first ground in a grinder. Depending on the raw material, the grain is reduced to, for example, a particle size of less than 1 mm. In contrast to the prior art, bran accumulating here is not screened out.

  • the following process step is the fermentation; After saccharification, a standard Saccharomyces fermentation is carried out at 30-40 ° C, which ends in a final ethanol concentration of, for example, about 5% by volume. Specifically, because of the frequent rejection of genetically modified biofuels, no genetically modified material or microorganisms suitable for this purpose should be used here.
  • the ethanol- ⁇ / vasergic mixture obtained is then concentrated in a rectification device to about 90 wt .-% ethanol.
  • the solution is further concentrated to at least 99.0% by volume of ethanol by means of a further dewatering treatment, for example an entrainer distillation or by molecular sieve technologies or pervaporation.

  • the resulting biogas will then continue to be used to generate electricity.
  • the process from the biogas production can - as is well known - so discharged or be fed to another, aerobic treatment.
