Anaerobic digestion of animal manure is looked upon as a strong option in safely reusing wastes or
transforming them into valuable materials and energy. This decomposition process that occurs within a
confinement contributes to pollution control as it presents with the following benefits; it reduces
biological oxygen demand (BOD) and chemical oxygen demand (COD) of wastes; it destroys
pathogenic microbes reducing the microbial load to a level which could be safely handled by humans
with limited health risks [16] and it destroys volatile fatty acids and many malodorous compounds
present in the feedstock and reduces the emission of greenhouse gases. Ultimately, it generates biogas
and high quality nutrient-rich fertilizer from animal manure thus upholds the concept of waste to
wealth in enhancing sustainability of development
