Construction and Demolition Waste Reduction in South Africa
摘要
Globally, the issue of excess Construction and Demolition (C&D) waste to landfill has been recognised and counteracted. However, South Africa, as a developing country, has yet to identify and implement adequate waste reduction measures. There is currently not much information on C&D waste reduction strategies and technologies available in South Africa, and this chapter is purposed at providing such information. This research aims to investigate the problem of C&D waste in South Africa by looking at the strategies and technologies available for reducing C&D waste. The quantitative research method was used to determine the awareness and implementation of strategies and technologies available in relation to waste reduction in South Africa. An online survey was created and sent to registered and candidate project managers. Responses from the survey were processed in Excel and illustrated in the form of figures and tables with their respective interpretations. The response rate from the South African project managers was low, and some provinces had few responses, limiting the representability of the sample. It was found that there was a weak awareness among project managers regarding the strategies and technologies available to reduce waste. It was also found that the majority of the project managers in South Africa are not implementing either waste reduction strategies or technologies. With an implementation rate of less than 13% on average, it is evident that the lack of implementation of waste reduction strategies and technologies among project managers is part of the reason that South Africa has such a waste problem. This study is beneficial because it builds an understanding of the available strategies and technologies that can be utilized in South Africa to reduce C&D waste.
