The technology of biodegradation of vegetable waste (solvent cake wormwood, plantain, ambrosia) by means of lactic acid bacteria symbiosis and enzymes which stimulate the process of biomass degradation of plant biomass has been investigated. The process of biodegradation was successfully completed in 7 days at temperature of 45°C, maintaining a pH of 3,5-4,3. As a result of biodegradation process of plant waste, bioethanol in amount of 3,26-11,9 g/l and enzymes in amount of 1,86-7,12 g/l using symbiosis of lactic acid bacteria was obtained. Experiments have shown that the greatest amount of bioethanol can be obtained by using enzymes. It has been established that in the case of enzymes use and lactic acid bacteria there is a complete hydrolysis of plant material, which allows its further use in animal feeding.
