“…It was observed that the pretreatment increased 0.2 m 3 and 2.2 m 3 methane as compared to unpretreated AD of CM (2.5 m 3 at pH 6.1 and 26.3 °C) and 5.9 m 3 at pH 6.9 from co-AD of CM and food waste (3.7 m 3 at pH 6.3). The co-digestion of NaOH-pretreated substrate and with the addition of inoculum (SwS) at neutral pH produced the highest methane yield of 40.81 m 3 in DPBD [92].…”

The control strategies adopted in formulation and anaerobic digestion (AD) process of chicken manure (CM) for the control and enhancement of biogas production are reviewed. The existing limitations and future challenges in the production of biogas from AD of CM are briefly discussed. The control strategy adopted for formulation is pretreatment of CM (physical, chemical, biological, and thermal) while strategies for AD include selection of optimal parameters (pH, C/N ratio, organic loading rate (OLR), and temperature), co‐AD with other substrates, and addition of supporting materials. The pretreatment of CM, selection of optimal parameters, Co‐AD of CM with other substrates, and addition of supporting materials overall enhance biogas and methane production due to increase of hydrolysis and C/N and decrease of ammonia inhibition, CO2 and H2S contents. The implementation of developed control strategies in continuous plants, development of new strategies, and use of supporting materials in combinations of two or three for better performance are the future challenges in the AD of CM. The control strategies had a significant impact on the efficient use of CM and improved biogas and methane production.

“…Несанкціоновані райони зберігання відходів птахівництва є істотним джерелом не тільки забруднення ґрунтів, водних об'єктів та підземних вод, але й причиною емісії парникових газів, прискореного зростання та розвитку яєць та личинок гельмінтів та мух, патогенних мікроорганізмів. Проблема екологічної небезпеки від накопичення пташиного посліду виникає у разі низької якості технологічного процесу видалення посліду, не належному його зберіганні та транспортуванні, використанні при виробництві добрив в якості органічного компоненту [1,2].…”

Environmental safety risks caused by the accumulation of poultry manure are discussed, along with the advantages and disadvantages of poultry manure treatment technologies. The attention is focused on the method of anaerobic digestion with biogas and high quality fertilizer production. In this work, the method of intensification of anaerobic digestion with the use of preliminary additional ultrasonic treatment in the process of anaerobic digestion of organic waste to produce biogas is investigated. The additional ultrasonic treatment enhances the decomposition of the organic waste and releases more energy for conversion into methane by physical disintegration of the substance and improvement of the chemical structure of the substrate through the free radicals released by the cavitation bubble collapse. The effectiveness of ultrasonic pretreatment in the anaerobic digestion process was laboratory tested by comparing the biogas yield and parameters of the anaerobic process. The selected method was monitored in terms of hydrogen value (pH), redox potential (ORP), total dissolved solids (TDS), and qualitative and quantitative composition of the biogas. Ultrasound treatment of the substrate at the pretreatment stages for the subsequent anaerobic digestion process has increased the biogas yield. Laboratory confirmed that the increase in biogas productivity of anaerobic digestion biosystems with pretreatment of the substrate with ultrasound compared to the control experiment without pretreatment increased by 1.3 times in twenty-five days of the study and the overall achievement of biogas productivity of 10 liters. Theoretically calculated reduction of the payback period from 5.0 to 2.5 years of the biogas plant implementation of the combined system of organic waste utilization with the additional installation of the pretreatment system. The possibilities of international grant platforms for financing and implementing innovative local biogas projects, particularly those focused on the community of Ukraine, are analyzed.
