Recycling Waste-to-Energy (WTE): Studies Carried-out on a Metropolitan City of the North-Eastern Nigeria

摘要

Studies on municipal solid waste (MSW) were carried-out in some selected locations from the Maiduguri metropolis. These wastes are produced and/or accumulated due to various human activities. Amongst the many factors that these wastes will course to the environment are: environmental degradation, insects, atmosphere (air) pollution, diseases, and disfigure the image of the city. In the effort to meeting the millennium development goals (MDGs) specification on environment, this paper is advocating that an appropriate solid waste management system/mechanism must be instituted. It is reasonable to recover energy from MSW through a variety of a process such as combustion pyrolysis and gasification. In this study, we estimated the energy content of the MSW from the Maiduguri metropolis in order to achieve its optimal system performances. It was determined that the quantity of solid waste that are been deposited on daily bases at some selected/various locations were respectively 10,000kg/m~2, 20,000kg/m~2 , 40,000kg/m~2, 20,000kg/m~2 , 10,000kg/m~2 from Bagga road, Mairi ward, Monday Market, Post Office, and University of Maiduguri campus. These values determined were compared with the reported data from the literature, were energy values of different materials when incinerated to arrive at the corresponding energy (power) that can be produced from Maiduguri metropolis MSW.
