FIELD: power industry.
SUBSTANCE: bioethanol obtaining method involves preliminary raw material treatment. Green raw material is collected and crushed, and fluid is obtained. Yeast or special alcohol bacteria are added to the obtained fluid. Fermentation process is performed during 3-5 days. Distillation is performed so that crude alcohol is obtained, and after that, rectification of crude alcohol is performed so that final product - bioethanol is obtained. In addition, as raw material for obtaining bioethanol there used is wild or domestic hogweed containing 17-31% of saccharose of budding phase to flowering phase.
EFFECT: reduction of use of cultures of food purpose as initial components for obtaining bioethanol; restricting the spread and harmfulness of hogweed as aggressive invasive type of plants.
