Abstract
Waste is a chemical ecological factor affecting sanitary sustainability of the environment, health of the population and social hygiene. Low capacity, insufficient funding and lack of environmentally friendly technologies in waste disposal and recycling may entail irreversible environmental changes. Waste is increasingly used not only as the secondary material resource, but also as the energy resource for obtaining the biogas with 80% methane content. The research encompasses recycling of food waste, outlines the rational waste recycling method with use of the biogas machine, describes the qualitative and quantitative characteristics of commercial biogas obtained from sugar industry waste, and identifies the general stages of methane formation in the sugar industry byproducts.The microbiological and biochemical regularities of the biogas formation process were studied. We analyzed the known information on biomethanogenesis stages and methanogenesis-supporting bacterial strains in sugar by-product biomass.The best conditions for the release of biomethane in a system with an organic substrate of sugar by-products have been studied. It has been established that the temperature and pH of the environment play a great role in the methanogenesis efficiency.The possibility of using biogas production for the purpose of generating ecologically clean renewable energy sources has been studied.
