Residential construction and demolition waste in Perth, Western Australia: Cost benefit analysis of best practices
Felmingham, Casey (2015) Residential construction and demolition waste in Perth, Western Australia: Cost benefit analysis of best practices. Honours thesis, Murdoch University.
In Perth, Western Australia the construction and demolition (C&D) industry contributes 50% of all waste generated. The recovery rate in WA for C&D waste is currently only 38% which is very poor compared to European countries as they are exceeding 80%. This project aimed to assess C&D waste generation in Perth to determine how waste recovery could be improved. Waste from three construction sites and two demolition sites was collected and collated to determine waste generation and composition and to identify areas for improvement. Also landfill sites, skip bin operators, and resource recovery facilities were surveyed on the cost of waste disposal to determine the most cost effective option. This study showed that the residential construction industry would generate approximately 881,000 tonnes of waste during 2015 using the predicted housing figures from HIA and UDIA. Also it shows that there is great variation with the generation of demolition waste due to the different site characteristics, which was shown by the two demolition sites of different sizes both generating nearly 300 tonnes of waste. Resource recovery was found to be the most cost effective option out of landfill, skip bins and resource recovery. The waste streams produced highlight that the main area of concern is rubble materials, concrete, sand, dirt, and broken bricks and tiles. Therefore better waste management of these wastes and possible recycling into waste derived materials is recommended. The findings from this study indicate that large scale changes are needed within the industry to increase resource recovery rates in WA, such as legislation change, more education, and the possible introduction of subsidy programs.
