Abstract
Waste management in the building industry in Hong Kong has become a major environmental issue in recent years. Of particular concern is the increasing amount of construction and demolition (C&D) waste being dumped at landfill sites. Greater consideration must be given to waste generation and management at the planning stage of a building development to reduce wastage levels. The causes and quantities of building construction waste generated on public housing building sites in Hong Kong have been analysed. Five public housing construction sites were selected for the study by regular site visits. Timber boards used in formwork were the most significant waste type requiring disposal followed by waste derived from wet trades. Waste generation could be significantly reduced by the use of precasting and system formworks. The major causes of wastes were improper preparation and handling, misuse, and incorrect processing. In general, little on-site waste sorting was carried out. Appropriate planning including the preparation of a detailed waste management plan is essential for effective waste minimization. At the construction stage, better house keeping and more vigorous on-site sorting of inert from non-inert materials are necessary. Waste indices calculated from waste monitoring data should be publicized and used for future waste estimations.Keywords
