One of the promising areas of processing organic waste from agriculture is through methane fermentation in biogas plants. They have important advantages over other methods of processing organic waste. Based on these problems, the article describes a method of processing organic waste under anaerobic conditions using electric pulse treatment of organic waste before loading into a biogas plant. The parameters of the production process of the bioenergy plant had the following values: humidity of organic waste 88-94%; the pressure of the gas phase in the bioreactor -2-3 kPa; the dose of daily updating of the mass volume in the bioreactor is 10% / day; the duration of one cycle of mixing 10 min; the frequency of daily mixing 17 days−1. Based on the equation, taking into account the listed optimal values of the factors, the biogas yield per 1 kg of OM was calculated and 0.146 m3 of BG/kg of OM was obtained. Laboratory and production results are given, as well as a comparison of the data obtained.

This article discusses the operation of a device designed to separate long fibers from fibrous waste generated in gin.In the course of the study, the number of fractions in the fiber mixture produced at the enterprise and the properties of short fibers were studied, a technological scheme of a new device for separating fibers was developed, the principle of its operation was presented and the main factors affecting its productivity were determined. Then the tests of the device in production conditions and their results were presented.
