Abstract
Waste characterisation data specific to African countries and cities are not generally available, though some regional evaluations have been made. Additionally, the income level of the generators has been shown to be correlated with the generation rate and composition of the municipal solid waste (MSW) stream. This correlation has been established in case studies of cities in OECD countries and on the basis of GNP for countries as a whole. Such regional and global-level statistics may be the most reliable bases available for inferences about the characteristics of the MSW stream in Africa. The limited available data suggest that the MSW stream in the typical African City at point of disposal is high in putrescible organic content. However, it is low in percentage of commercially recyclable components and too low in heating value for energy recovery by incineration (UNEP International Environmental Technology Centre, 1998).
