Optimization of Conditions to Produce Biogas Methane from Dog Feces by Anaerobic Digestion: Systematic Re-view and Technological Perspectives

Summary/Abstract: Sustainable organic waste management has spurred research on methane bi-ogas production from various sources, including animal fecal waste. This study presents a systematic review on the anaerobic digestion of dog feces with the aim of optimizing conditions for methane biogas production. Scien-tific databases such as ScienceDirect, Springer, MDPI and ResearchGate were analyzed, selecting a total of 38 studies under the PRISMA methodolo-gy. The results indicate that methane production efficiency is influenced by organic matter composition, temperature, pH and microbial synergy in an-aerobic fermentation. It is concluded that optimization of parameters such as carbon/nitrogen (C/N) ratio and implementation of advanced anaerobic di-gestion technologies can significantly increase biogas production from these wastes. This study contributes to innovation in health and welfare technolo-gies by offering a sustainable solution for animal waste management, reduc-ing pollution and improving environmental quality. In addition, it contrib-utes to the thematic axis of sustainability and environment by demonstrat-ing how organic waste, such as dog feces, can be harnessed as a renewable energy source, promoting the transition to a greener and healthier future.
