Faecal sludge dewatering and carbonisation for the production of fuel briquettes

Abstract

Globally, there is an increasing demand for energy to support development needs. The challenge of inadequate energy resources is more pronounced in developing countries/ regions like the Sub Saharan Africa. The quench for energy resources has translated into environmental degradation contributing to climate change. The waste industry is also growing with corresponding increase in population and urbanization. Most of the wastes especially municipal and domestic wastes contribute to global warming. This study sought to devise means of utilizing some waste streams like faecal sludge to partly address the energy deficiency in developing countries, but also trigger studies in similar line. The application of the findings in the study will also solve public health and sanitation issues in urban or peri-urban areas. In this paper, one will find effective and efficient means of dewatering and carbonizing faecal sludge to produce fuel briquettes for cooking.
