Одна из таких технологий – переработка навоза крупного рогатого скота в подстилку для животных. (Цель исследования) Экономически обосновать применение различных вариантов технологии производства подстилки из навоза в условиях функционирующего животноводческого предприятия. (Материалы и методы) На примере молочной животноводческой фермы с поголовьем 100 коров дойного стада рассмотрели три варианта реализации данной технологии: I – разделение навоза на фракции с последующей аэробной ферментацией твердой фракции навоза в установках барабанного типа; II – смешивание несепарированного навоза с торфом и последующая аэробная ферментация в установках барабанного типа; III– смешивание несепарированного навоза с торфом и последующая аэробная ферментация в установках камерного типа. Сравнили капитальные, эксплуатационные и трудовые затраты, а также срок окупаемости. (Результаты и обсуждение) Определили комплекс необходимых сооружений и оборудования для переработки навоза и хранения полученного продукта для всех вариантов. Провели экономическую оценку указанных вариантов. Показали, что для варианта I капитальные затраты на внедрение составили 18,2 миллиона рублей, эксплуатационные – 8,9 миллиона рублей, трудозатраты – 5,1 человеко-часа на тонну, срок окупаемости – 2,1 года. Выявили, что вариантам II и III соответствовали высокие затраты, то есть производство подстилки с добавлением торфа оказалось убыточным. (Выводы) Определили наиболее эффективный и экономически обоснованный вариант технологии переработки навоза: разделение его на фракции, аэробная ферментация твердой фракции в установках барабанного типа и длительное выдерживание жидкой фракции в навозохранилище. Варианты II и III экономически нецелесообразны.</p></abstract><trans-abstract xml:lang="en"><p>Development and testing of new more effi cient and environmentally friendly waste management technologies is one of the priorities of agroecology aimed at introducing the basic principles of the sustainable use of natural resources. An example of such a technology may be the recycling of cattle manure into the bedding for farm animals. (Research purpose) Feasibility study of diff erent technological options for the production of bedding from manure under conditions of an operating livestock enterprise. (Materials and methods) In the study, three options of this technology were considered as exemplifi ed by a dairy farm for 100 milking cows: Option 1 – separation of manure into fractions followed by aerobic fermentation of the solid manure fraction in a drum-type fermentor; Option 2 – mixing the unprocessed manure with peat and its subsequent aerobic fermentation in a drumtype fermentor; Option 3 – mixing the unprocessed manure with peat and its subsequent aerobic fermentation in a chambertype fermentor. The author has estimated capital and operation costs as well as labour inputs and payback period. (Results and discussion) The number of facilities and equipment required for manure recycling and the resulting product storage has been calculated for each option. The author has made an economic assessment of the three options. For Option 1, the capital costs of implementation amount to 18.2 million roubles, operating costs – 8.9 million roubles, labour inputs – 5.1 man-hour per tonne, and the payback period – 2.1 years. It has been revealed that options 2 and 3 feature high capital costs, therefore, bedding production with the use of peat proved to be ineffi cient. (Conclusions) The study has allowed to determine the most effi cient and economically feasible technological method of manure recycling: manure separation into fractions with subsequent aerobic fermentation of the solid fraction in a drum-type fermentor. Options 2 and 3 have been found economically unfeasible.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рециклинг навоза</kwd><kwd>молочная ферма</kwd><kwd>подстилка</kwd><kwd>аэробная ферментация</kwd><kwd>экономическая эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>manure recycling</kwd><kwd>dairy farm</kwd><kwd>bedding</kwd><kwd>aerobic fermentation</kwd><kwd>economic effi ciency</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Брюханов А.Ю.
