An assessment of literature on construction and demolition waste management barriers in Sub-Saharan Africa: lessons and implications for sustainability in South Africa

This paper discusses the challenges associated with the management of construction and demolition waste and its implications on environmental wellbeing and sustainability. Using existing and anecdotal literature, evidence suggests an increase in the demand for infrastructure for domestic and commercial purposes, and this in turn is exerting massive pressure on the construction industry to absorb and meet increased levels demand. This development has however, been accompanied by the generation of excessive quantities of waste, making it extremely difficult for urban managers in Sub-Saharan African cities to effectively and comprehensively manage construction and demolition waste. A major challenge being that this type of waste exists in forms that require extensive injection of resources for systematic separation far beyond the budgetary positions of many of these cities. In view of this, this paper is an attempt to systematically review and synthesise existing knowledge with a view of creating an inventory of the challenges associated to construction and demolition waste management and suggest possible solutions and approach for transforming this waste into a resource.
