Item Non-Waste Technology for Utilization of Tree Branches(Applied Sciences (Switzerland), 2022-09-04) Lyashenko, S. V. ; Gorbenko, O. V. ; Kelemesh, A. O. ; Kalinichenko, A. V. ; Stebila, J.; Patyka, V. P.; Ляшенко, Сергій Васильович; Горбенко, Олександр Вікторович; Келемеш, Антон Олександрович; Калініченко, Антоніна Володимирівна; Патика, Володимир ПилиповичThe trees (e.g., fruit or decorative) growing on the homestead plots of private households provide opportunities for sustainable biomass obtained from pruned branches every year. Profitable production of fuel material requires high-performance equipment and methods by which wood chips can be produced at low cost. The practice of chopping tree branches shows that not all chopping machines are suitable for use on homestead plots. This research gives the five-year test results of a developed and patented tree branch chopping machine under special operating conditions. The machine was tested under the conditions of the homestead plot of a private household in the Poltava region, and the engineering parameters to set up the chopper were determined. It is recommended to set a 0.3404 radian (19 degrees 50 min) angle on the chopper to cut tree branches as well as to set the size of the cutting knives’ protrusion above the disc plane within 0.0120 m. As a result of the correct settings, the power consumption of the chopper motor will be W = 1.3549 kW, which is an optimal value for the studied chopper. The research results made it possible to provide instructions for the tree branch chopper’s operation and to adapt it to the conditions of homestead plots.Item Production of biogas and biomethane from agricultural raw materials in the Poltava region(Полтавський державний аграрний університет, 2023) Lyashenko, S. V.; Ляшенко, Сергій ВасильовичPoltava fields are able to provide the whole Ukraine and Europe with biogas. Energy is the blood of the modern economy. No organization and no enterprise can exist without it. Every day russian terrorists they attack Ukrainian energy infrastructure. It will be extremely difficult to restore the combined heat-and-power plants and thermal power plants that they are trying to destroy. The experience of farmers from the Poltava region and many other regions of Ukraine proves that electricity and even fuel for engines can be successfully "grown" in the fields.Item Waste usage as secondary resources(Procedia Environmental Science, Engineering and Management (P - ESEM), 2020-10) Gorbenko, O. V. ; Lyashenko, S. V. ; Kelemesh, A. O. ; Padalka, V. V. ; Kalinichenko, A. V. ; Горбенко, Олександр Вікторович; Ляшенко, Сергій Васильович; Келемеш, Антон Олександрович; Падалка, Вячеслав Вікторович; Калініченко, Антоніна ВолодимирівнаThe 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.
