Emerging waste reduction technologies for the design and construction of buildings

摘要

The construction sector is one of the largest contributors to Canada's solid waste disposal stream. Public Works and Government Services Canada (PWGSC) is investigating, developing and implementing various techniques to reduce the adverse impacts resulting from conventional design and construction practices. A set of comprehensive improvements to the design processes, maintainability and serviceability of building systems, in order to enhance disassembly possibilities, is described within this paper. Waste diversion practices including the recycling of concrete, steel, non-ferrous metals, gypsum and wood are examined. Technical consequences associated with implementing the recommended procedures are identified and discussed.
