“…¼ 160 kg animal manure þ 160 kg water ¼ 320 kilogram (13) The minimum withholding time or retention time of input material (salary) in a small biogas plant is 45 Therefore, the digester tank must have a minimum capacity of about 14.4 cubic meters to produce 8.0 m 3 of gas per day from the daily input of 160 kg of animal manure. Suitable dimensions for a 14.4 m 3 digester are a radius of 1.96 m and a depth of 1.19 m.…”

“…Anaerobic digestion (AD) technology, biomass densification, and direct combustion are a few methods that potentially extract energy from animal manure. [ 45 ] Anaerobic digestion is used to treat a variety of substrates with high organic content, including livestock manure, food waste, municipal waste, and industrial waste. [ 46 ] Using anaerobic digestion technology to generate biogas as a nonfossil fuel is cheap and environmental friendly.…”

This research is a numerical study, with simulation and experimental investigation of a novel photovoltaic and biogas hybrid renewable energy system. PVSYST simulation software is used to evaluate the energy generation of photovoltaic (PV) systems installed at optimum tilt angle and interrow spacing, as well as measure the performance ratio and system losses. The results obtained from simulations show that annual energy production from designed PV system is 16 654.80 kWh year−1 and its annual specific energy production is 1556.5 kWh kWp year−1. The average annual performance ratio is about 84.3%, normalized array production is 3.23 kWh kWp day−1, normalized system losses are 0.07 kWh kWp day−1, and normalized system production is 3.16 kWh kWp day−1. With SuperPro Designer software, a model is developed for simulating anaerobic digestion for treating animal manure to produce biogas. The simulation yields 88.13% of CH4 and 6.49% of CO2. The performance of the installed experimental setup is examined for 30 d. The maximum load demand of all houses is 46.902 kWh, whereas maximum energy produced by a hybrid PV/biogas system is 61.06 kWh. The payback period for a hybrid photovoltaic/biogas system is estimated to be 4.47 years and levelized cost of energy is 0.0186 USD kWh−1. The hybrid PV/biogas system results in net CO2 mitigation of 20.45 tCO2(e).

“…With a view to lowering environmental threats in recent years, Bangladesh has experienced an increase interest in biogas production from waste for environmental, economic, political, technological, and social reasons 17 . Simultaneously, farm animals waste, particularly farm animals' manure, is an extraordinary supply of bioenergy 18 . Biogas from anaerobic digestion (AD) of animal manure can play an influential role in reducing dependency on fossil fuels 19,20 .…”

Increasing prices of conventional energy sources and ongoing environmental pollution have encouraged policymakers to search for sustainable energy resources. In developing countries, livestock waste is often mismanaged and negatively impacts the environment. Bioenergy production from agricultural and animal wastes can be a viable solution. This study conducted a month‐wise survey on a multipurpose farm and a dairy farm in Chattogram, Bangladesh, to estimate the bioenergy potential from farm livestock waste. Based on the survey, mathematical modeling was applied to estimate the selected farm's theoretical bioelectricity, biogas and biofertilizer production potential. The analysis shows that the multipurpose and dairy farm have an annual biogas production potential of 209,660.2 and 1,205,035.5 m3, generating 3.77E+05 and 2.17E+06 kWhyr−1 of bioelectricity, respectively. The multipurpose farm and the dairy farm could generate 982.03 and 16092.49 tons of bio manure yearly and had an annual biofertilizer potential of 64.36 and 2090.91 tons. Both environmental and economic analyses show that both farms have good greenhouse gas mitigation potential and can earn significant revenue by selling electricity and biofertilizer in the market. The outcome can provide valuable guidelines for policymakers to invest in bioenergy production from farm animal waste.

“…In some studies, the significant contribution of nitrous oxide (N 2 O) emissions, from grazing land to global warming, has been highlighted, including pastures and large-scale breeding farms [20,21]. It has been revealed that the nitrogen deposition from livestock excrement dictates the spatiotemporal pattern of global change [22].…”

In this study, mathematical models are used to estimate the emissions of livestock excreta (LE) generated by China’s livestock industry more accurately. Also, the spatial relationship between provinces is analyzed. LE emissions are predicted for the next decade through appropriate parameters and non-parametric models. Additionally, a literature review is conducted to propose two hypotheses. As revealed by the research, there are four stages that LE emissions experience over time. From 2017 to 2021, LE emissions showed a trend of steady increase, suggesting a stronger awareness of the issue and the enforcement of more measures related to management and emission reduction. According to the results of a spatial analysis, there was no significant positive or negative correlation present between LE emissions in different provinces of China. In the selection of the prediction model, the BP-RE model achieved the best predictive performance. According to the prediction results, the fresh weight emissions from China’s livestock industry will increase by 24.53% by 2031, while dry weight emissions will decrease by 28.06%. Large-scale aquaculture farms show an upward trend, with fresh weight and dry weight emissions rising by 11.16% and 2.05%, respectively. Therefore, in light of this study’s findings, it is crucial for China to pursue additional measures in reducing LE emissions, despite the implementation of existing management policies. These insights can inform the development of livestock and poultry manure management policies and resource utilization strategies for the coming decade.
