FEATURE INGENIEUR Sustainable Waste Management Practices for the Construction Industry By Sivapalan Kathiravale, Shanmuga Kittappa, Noor Mohd Syeqqal Ismail Environmental Preservation and Innovation Centre Sdn Bhd (EPIC) Hj. Mohd Khairolden Ghani, Khairul Nizam Anuar Bashah Construction Research Institute of Malaysia (CREAM) Zuhairi Abd Hamid, Haji Razuki Haji Ibrahim Construction Industry Development Board Malaysia (CIDB) The construction industry in Malaysia has been quite robust for the last few years with doubledigit growth, and this is expected to continue in the future. The construction industry is recognised as one of the key industries in the country with a 10% contribution to the nation’s gross domestic product (GDP). Moving towards a developed nation, the number of construction projects is expected to increase massively. The demand in implementing major infrastructure projects, together with the construction of commercial buildings and housing development programmes will produce a large amount of construction waste. In accordance with the increasing global acceptance of sustainable development, efficient waste management needs to be emphasised. Under the 11 th Malaysia Plan (11 th MP), holistic waste management is highlighted as one of the strategies in adopting sustainable consumption and production concepts. Construction waste in the 11th MP lists the types of waste that should be managed in a holistic manner. Unfortunately, the plans formulated under the 11th Malaysian Plan did not work out but CIDB has taken a bold step in preparing a training module for all construction workers to ensure that sustainable waste management is enshrined in the construction industry. Realising the importance of training and changing workers’ mind set, CIDB through CREAM engaged EPIC to develop a comprehensive training module that will be used to enhance the understanding and put into practice sustainable construction waste management in Malaysia. Rapid developments have led to a rapid increase in the generation of construction waste for developing countries such as Malaysia. Unmanaged construction waste results in a negative impact on: - a) The environment - climate change, water and soil pollution, air pollution, ecological imbalance; b) The social and health wellbeing - health hazards, use of public space, proliferation of pests and impact on working safety; and c) The economy - reduction in environmental resources and energy usage, international reputation and effect on tourism. Despite realising these impacts, the systems adopted in managing construction waste in the country are still at a very poor level. The generation of waste in the construction industry needs to be examined by looking into the whole life cycle of a building – planning, design and procurement; construction; occupancy; operation and maintenance; and renovation 36 VOL 82 APRIL-JUNE 2020
