“…Preprocessed chicken offal and feathers, if they can release their high methane potential quickly, can, to some extent, increase the gas production of large-scale chicken farm biogas projects. Additionally, the anaerobic treatment of chicken's offal and feathers provides a resource recovery method for the harmless treatment of farm waste, contributing to circular economy practices as posited in research [13,17,22].…”

To standardize, systematize, and improve the efficiency of the evaluation of biodegradable materials for large-scale biogas projects to support clean and sustainable energy development in emerging economies from a sub-Saharan African perspective, this paper analyzes and fits the potential for methane production (biochemical methane potential, BMP) and degradation kinetics of materials based on the gas production and degradation dynamics obtained from methane potential experiments. The first-order, modified first-order, and Gompertz models are used for analysis and fitting. The Gompertz model shows higher accuracy in fitting the methane production potential curve of screened materials, and the fitted methane potential values are close to the experimental values. When using BMP1% (cumulative gas production reaching 1% of cumulative gas production per day) as a quantitative indicator for the methane production potential of materials, the cumulative methane production reaches over 85% of the cumulative methane production at the end of the experiment. The BMP test time is shortened by 26.98% to 72.06%. Among the screened materials, the methane production potential (calculated using BMP1%) of dry rice straw, maize leaves, fresh rice, soybean straw, maize stalks, chicken manure hydrolysate, chicken feathers, kitchen/food waste, and chicken offal are 234.14, 241.01, 253.34, 331.40, 305.80, 508.41, 510.10, 630.7, and 621.32 mL/g, respectively. The kinetic parameters show that among the nine materials, cellulose materials (except for maize stalks and soybean straw), chicken manure, and kitchen waste are easily degradable materials. In contrast, chicken feathers and offal are slowly degradable materials. The study posits that comparing standardized methane production potential and methane production kinetic parameters among materials improves the efficiency of screening materials and is critical for biogas projects.

“…Organic material is mostly converted into the gases carbon dioxide and methane through the multi-step biological process of anaerobic digestion (AD), with traces of nitrogen, ammonia, hydrogen sulfide, and hydrogen vapor being produced. (Rahimi et al 2024). Using inexpensive feedstock or even industrialized and municipal organic wastes, the AD process is a tried-and-true method that may satisfy energy demands like fuel, heating, power, and other applications (Kathi and Prasad 2024).…”

Sustainable agricultural practices necessitate the effective treatment and usage of waste produced throughout the farming and harvesting process, which is known as agricultural waste management. It starts by outlining the many agricultural waste sources, such as crop leftovers and animal dung, agrochemicals, and packaging materials. The innovative waste management technologies and strategies such as composting, anaerobic digestion, bioenergy production, and precision agriculture techniques. These advancements offer opportunities to mitigate environmental pollution, enhance soil health, and promote resource efficiency within the agricultural sector. Advancements in technology, policy frameworks, and collaborative approaches, stakeholders can foster sustainable agricultural practices that promote environmental stewardship and support the long-term viability of agricultural systems.
