Table 2: Composition of construction waste generated in Peninsular Malaysia. Construction waste Total wastage (tons) Total wastage (%) Metal 10,478.85 3.85 Timber/wood 17,529.75 6.45 Concrete 12,487.12 4.59 Bricks/blocks 3,685.62 1.36 Packaging material 3,650.28 1.34 Ceramic/tiles 40.83 0.02 Soil/aggregate 2,2482.45 8.27 Plastic material 1,506.95 0.55 Cardboard 24.51 0.01 Gypsum board 174.44 0.06 Mixed waste 199,887.35 73.50 Corp) which defines Construction and Demolition waste in two categories, which are: a) Residual solid waste - means any construction solid waste which is not reused, recycled or composted and can be replaced in a receptacle. b) Recyclable construction solid waste - means any construction solid waste which is separated for recycling. Based on this definition, SW Corp provides several examples of Contruction and Demolition waste (C&D) that could be generated from various types of construction development and construction activities as shown in Table 1. Construction and Demolition Waste Generated in Malaysia According to Laporan Akhir Kajian Sisa Binaan 2018, a research conducted by CIDB, the composition, quantity and corresponding percentage of each type of waste generated is as listed in Table 2, while the overall generation and recycling rates are as follows:- a) Total C&D waste generated in Peninsular Malaysia = 271,948 tons b) Total C&D waste recycled in Peninsular Malaysia = 37,263.51 tons c) C&D waste recycling rates in Peninsular Malaysia = 13.7% On the other hand, Figure 1 shows the amount of material recycled for each type of waste in Peninsular Malaysia. Although there are materials being recycled, the amount is at a very low level. Therefore, the recycling amount needs to be elevated through the right training and workers’ mind set. Legislation for Construction Waste Management in Malaysia The Department of National Solid Waste Management - Solid Waste and Public Cleansing Management Act 2007 (Act 672) This provides for and regulates the management of controlled solid waste and public cleansing for the purpose of maintaining proper sanitation. It gives the Federal Government executive authority with respect to all matters relating to the management of solid waste and public cleansing. Under the Act, controlled solid waste is categorised as commercial solid waste, construction solid waste, household solid waste, industrial solid waste, institutional solid waste, imported solid and public waste. This legislation applies throughout Peninsular Malaysia and the Federal Territories of Putrajaya and Labuan. Solid Waste and Public Cleansing Management Act 2007 (Act 672) - Scheme for Construction Solid Waste (Regulations 2018) This regulation provides the scope of preliminary, duties of construction solid waste generators or persons in possession of construction waste, duties of licensees 39
