The invention relates to processes for degradation of hard-degrading waste, in particular of distillery waste obtained as a result of alcohol distillation. The process, according to the invention, includes the hydrolysis of waste, their dechlorination and anaerobic fermentation with biogas obtaining. The hydrolysis is carried out by mixing the distillery waste with alkaline solution of sodium hypochlorite, with a content of sodium hypochlorite with respect to OCU of the distillery waste of (0,3...0,5):1, with addition of copper sulphate in the quantity of 0,05...0,10 g/L, at the temperature of 50...90?C, at the same time the alkaline solution of sodium hypochlorite contains 25...30 g/L of sodium hydroxide and 160...180 g/L of sodium hypochlorite, and dechlorination of the hydrolyzate is carried out with sulphurous anhydride.
