Abstract
Over the years, the need for more animal protein to sustain an exponentially increasing population has led to an obvious increase in livestock production through the establishment of large, industrial sized animal farms. This has given rise to monumental increase in animal dung e.g. pig dung, with attendant waste management challenges that need to be addressed. The use of dung so far for fuel and heating has however proved inadequate to take care of the accumulation of dung from these large farming concerns. There is therefore a desperate need for technologies that can systematically ensure the removal of all animal, human, and industrial wastes from the environment. One such technology has come to fruition with the introduction of biogas technology which involves the conversion of all organic wastes from agriculture, livestock, industries, municipalities and other human activities into energy and manure through the process of anaerobic digestion (biometanization). Yet others are at various incubation stages like the ongoing study to blend pig dung into a perfect cooking solid biofuel. This paper reviews environmental and health concerns of pig waste production and its potentials as biofuel source.
