“…6.0, and 30.0 mm. It was found that the maximum amount of biogas was produced from raw materials with a particle size of 0.088 and 0.40 mm [79]. Previous studies suggest creating a homogeneous environment in the reactor, and it is recommended to use only crushed waste less than 2 mm in size [80].…”

“…The temperature regimes of the process of obtaining an inoculum and anaerobic fermentation should be the same, as the species composition of the methanogen community depends on temperature. To do this, the inoculum is taken from operating biogas plants before adding to the batch reactors; in [75][76][77][78][79], the selected mixture was fermented for 14 days at thermophilic or mesophilic temperature conditions, depending on the operating temperature of the reactors.…”

“…A modified version of Formula (4) is found in the works of other researchers (mL CH 4 per 1 g of dry matter) [76,79] The biochemical biogas yield potential (Vbg) is used as the most relevant indicator in assessing the degradation of organic matter [76]. Biodegradation of organic matter (BD) during anaerobic fermentation is estimated as the ratio of the actual biogas yield (Vbg) to the theoretical biogas yield (( 5) and ( 6)):…”

“…The main indicators of the efficiency of the process of decomposition of organic matter as a result of anaerobic fermentation are a decrease in the content of dry matter [81], a decrease in the content of organic matter, the content of volatile fatty acids [8], the volume of biogas released with a percentage of methane, a change in pH values, and the content of ammonium [8,79,81].…”

Human activity and modern production contribute to the formation of a certain amount of waste that can be recycled to obtain useful products and energy sources. Today, the higher the level of industrial development, the greater the amount of waste generated, and as a result, the more important the need for disposal. A similar pattern is typical for any human production activity; as a result of large-scale production, at least 70–80% of waste is generated in relation to the amount of raw materials used. The large-scale use of polymeric materials and the plastic waste generated after their use lead to environmental pollution. While a small part of the waste is utilized naturally due to the vital activity of soil microorganisms, and a part is purposefully processed by humans into products for various purposes, a fairly large amount of waste occupies large areas in the form of a variety of garbage. After the removal of garbage by incineration, the liberated territories cannot be transferred to agricultural land due to the high content of harmful contaminants. The harm to the environment is quite obvious. In practice, certain types of waste consist of more than 70% content of valuable substances that can find further practical application in a wide variety of industries.

“…The research aims to use PM and BD to generate biogas in order to meet the energy needs of people and to save the environment that has been degraded as a result of inappropriate disposal of selected waste. The anaerobic co-fermentation technique was used to treat poultry manure and buffalo manure [65].…”

Improvement of Biogas Yield by Pre-Treating Poultry Waste with Bacterial Strains

et al. 2021

Poultry waste is increasingly used as a substrate for the methane fermentation process in a biogas plant. However, not all waste materials processed in the meat industry meet the criteria for optimal process management and cost-effective methane efficiency. An example may be centrifuged biological sludge, etc. Treatment of such material used as a substrate by introducing new metabolically and enzymatically active strains of bacteria could be beneficial for the fermentation process in a biogas plant and provide increased energy efficiency. The aim of the study was to compare the amount and quality of biogas obtained from biological sludge from the processing of poultry vaccinated with metabolically diversified bacterial inoculum after initial incubation of the batch before the actual process in a biofermenter. Laboratory tests were carried out in accordance with the guidelines contained in the DIN 38 414-S8 and VDI 4630 standards. Based on the obtained results, it was found that the optimized biological sludge can be used as a substrate in the methane fermentation process in a biogas plant. The material processed by the combination of bacterial strains marked with the symbols A/C, E/G, and F/H showed a significantly increased efficiency of biogas, including methane, compared to the non-grafted material. This is a good predictor for industrial applications, process feasibility, economic viability, and environmental sustainability that should be compiled based on the results obtained from this study.
