Environmentally Friendly Agricultural Waste Management Technology

Abstract

As part of this study, the methods were analyzed and developed, aimed at solving the topical environmental issue involving the management of organic waste resulting from human activities. A special attention is given to the issue of organic waste management and minimizing the environmental impact. Organic wastes disposed on landfills pose high-level risks to the relevant ecosystem. The study identified some key factors influencing the intensity of biogas production. They include biomass temperature and humidity, its mixing technique and frequency, and fermentation duration. The key requirement for obtaining biogas is the provision of anaerobic conditions in the bioreactor to maintain the intense life activities of methane-producing bacteria. This paper deals with studying the anaerobic digestion of chicken manure with molasses being added. To produce biogas, we selected the optimal mixing ratios, namely manure-to-water ratio of 1:3 and manure-to-molasses ratio of 1:1. Anaerobic digestion ran in a mesophilic temperature mode. The study has shown that adding molasses into chicken manure leads to increasing the biogas yields by 23.62 %. Using beet molasses to intensify the process of anaerobic digestion is a promising research area solving several tasks simultaneously.
