Waste usage as secondary resources. Procedia Environmental Science, Engineering and Management. 2021. Vol. 8, No. 2. P. 417–429.ISSN: 2392 - 9537https://dspace.pdau.edu.ua/handle/123456789/15262The current state of waste management in Poltava region is summarized in this article. In this article were determined places of accumulation and the influence of population size on the volumes of domestic solid wastes formation. Here also was analyzed dynamics of changes in the production of domestic solid wastes in rural areas and in cities. The morphological composition of domestic solid wastes was determined due to researches during 2017-2019. In the article was conducted comparative analysis of the data of changes in the percentage of components, which are part of domestic solid wastes depending on the time of year. It is determined that about 55% of the waste is the organic part of domestic solid wastes. Using certain technologies organic part of domestic solid wastes can be processed into valuable products. The technology of processing the organic component of domestic solid wastes into compost adapted to conditions of private farm households is offered in this article. Here are justified the design parameters of small-sized household chopper for compost production and are given technical conditions of machine usage the in conditions of private farm households. Here also was calculated economic feasibility of machine usage for three farm households for the purpose of processing the organic component of domestic solid wastes into compost. The costs for equipment, materials and inventory were about 2.835 thousand EUR. Costs for electricity, water, wages, etc. were 4.379 thousand EUR. The cost of production of one kilogram of compost was 0.093 EUR/kg. The payback period of the project is 9 months. The use of new developed equipment for the processing of organic component of domestic solid wastes makes it possible to reduce the ecological environmental impact to a considerable extent. In addition, the use of wastes as secondary resources makes it possible to obtain funds for private farm households.enArticle
