Efficiency of Utilization of Wastes for Green Energy Production and Reduction of Pollution in Rural Areas

The aim of the study is to present the possibilities of simultaneous production of green energy and reduction of pollution in rural areas. Actions taken by small family businesses are in line with the goals of a low-carbon economy. The paper presents the results of research on the possibility of using ecological energy for production and, at the same time, utilizing harmful waste generated in farms in rural areas. Within a month, a medium-sized biogas plant can produce about 35–40 GJ of energy (depending on the input material). Biogas production may be of significant importance from the point of view of environmental protection, especially in the case of overproduction of animal waste and slaughterhouse materials. The production and use of energy generated from agricultural waste give a great opportunity for diversification and an increase in income of family farms. In addition to financial, energy, and environmental gains, we can obtain a very valuable fertilizer that is easily absorbed by plants in field cultivation. Energy efficiency is an important parameter in biogas production. The possibility of reducing pollution in rural areas and the possibility of using digestate as a fertilizer and an innovative addition to biocomposites.
