title: Towards zero waste: a case study in the City of Tshwane.
abstract: Tshwane is presently landfilling all of its municipal solid waste (MSW) with no pre-processing or minimization efforts. This is a result of the available capacity of its existing landfills, thought to be able to satisfy the city's needs for, at most, the next 10 years. It is possible that the authorities will not wake up to the problem before it is too late. This study addresses these challenges. This study first identified and evaluated technologies available in developed countries for processing the various components of the MSW stream, appropriate to local conditions, as an alternative to landfilling, to ensure that these components will be either reused, recycled or rendered harmless to the environment before disposal. Then most appropriate technologies for Tshwane were selected and assembled into an optimal configuration to achieve a zero waste situation in Tshwane within a decade or two. This represents a significant change in MSW management in Tshwane, from total landfill to zero waste to landfill. Although the study focused on Tshwane, it can be argued that the findings can be implemented in any other South African municipality, and even implemented in other emerging countries.
