These wastes contain sugar, albumins, lipids, and vitamins that decompose under the action of microorganisms existing in nature and, in so doing, pollute the environment. The use of wastes in plants operating on biogas makes it possible to obtain great economic benefits. It was established that the best conditions for the obtaining biogas from pineapple wastes are realized in the case where Methanobacterium strains are used for increasing the rate of fermentation of these wastes and the wastes have a temperature of 35-45oC, a pH index of 7-7.5 at the initial stage of their fermentation, and a C/N ratio of 30/1. Under these conditions, the MT3, MT5, and MT7 strains of Methanobacterium yield the maximum amounts of biogases containing, respectively, 57.4% of CH 4 and 36.1% of CO 2 , 57.2% of CH 4 and 36.3% of CO 2 , and 57.4% of CH 4 and 36.2% of CO 2 .
