Husna 1 *, R.M.R. Ahmad 2,1 , R.E. Intan 2,3 and C.H. Asmawati 1Throughout the years, the construction industry has made an important contribution to the Malaysian economy.Moreover, the Ninth Malaysia Plan (2006–2010) has also played a significant role in the demands of executingmajor residential housing project developments where it has been observed that construction waste was one ofthe priority waste streams. Due to the increasing number in the population that is actively involved in economicactivities, and the modernization of the country, the types of construction waste that are being produced,and identifying the source such as waste are becoming more complex. Therefore, appropriate actions andapproaches are needed to be taken with respect to its effective management in handling the solid waste fromconstruction sites. This paper is intended to review the issues and the challenges enclosed within the supplychain management mechanisms in order for improving construction waste management. Throughout thisreview, useful information and better understanding concerning the current issues, challenges and the supplychain management mechanisms would be made inclusive in the field to be explored. The findings would alsoassist in improving the quality and awareness on the construction waste management that is being practiced.Key words: Construction waste; construction waste management; supply chain management; qualityThe construction industry plays a significant role in helpingthe nation to achieve sustainable development. Moreover,in achieving the quality of life among residents, the ninthMalaysia Plan (RMK9) had concentrated in providingsufficient residential housing project developments.Based on RMK9 (2006–2010), the demands on theresidential housing project development approximatelyaround 709 400 units with the highest proportion isSelangor (19.2%), followed by Johor (12.9%), Sarawak(9.4%) and Perak (28.2%) (Economic Planning Unit 2006).The RMK9 target on residential housing project is less thanthe completed residential housing project in RMK8 (2001–2005) which is 844 043 units. Although, the demands forthe residential housing project developments in RMK9are decreasing, the achievement of development will raisethe target referred to the completed residential housingdevelopments for RMK8 (2001–2005). Therefor, thecompleted units of residential housing was 844 043 unitsmore than the target which was 615 000 units (EconomicPlanning Unit 2006).With the demands in implementing residential housingdevelopment, it is shown that the construction sector isbeing expanded and developed. Due to the factors ofconstruction stage, type of construction work and practiceson site, the construction sector will produce the amountand the types of waste (Begum et al. 2007). The mostquantity of waste generated is from waste materials orconstruction waste materials. Based on the Solid Wasteand Public Cleaning Management Act 2007 (Act 672)(Solid Waste and Public Cleaning Department 2007),construction solid waste is “any types of solid waste that1 1Faculty of Civil Engineering, Universiti Teknologi Mara, Shah Alam, Selangor, Malaysia2 Institute for Infrastructure Engineering and Sustainable Management, Faculty of Civil Engineering, University Teknologi Mara, ShahAlam, Selangor, Malaysia3 Malaysia Institute of Transport, Universiti Teknologi Mara, Shah Alam, Selangor, Malaysia* Corresponding author (e-mail: husna_civ@yahoo.com.my; ahmad299@salam.uitm.edu.my; intan@salam.uitm.edu.my)59
