Abstract
Waste is becoming a major issue to manage with any significant growth. Despite the fact that there are a few existing studies in Malaysia that have developed waste management theories, existing waste management is given less attention in the manufacturing site. It is crucial to investigate the construction waste handling processes from generation to final disposal. Thus, the goals of this study are to identify different types of construction waste, determine the causes of construction waste by materials, and compare waste management practises in four precast concrete plants in Johor, Malaysia. This study observed the manufacturing process of precast concrete elements and interviewed manufacturer staff, including production managers and engineers. According to the findings of this study, hard concrete, wet concrete, steel, timber, and PVC are the most common types of construction waste found in precast concrete plants. Meanwhile, leftover concrete from mixer trucks, items rejected by inspectors, poor workmanship and mishandling by workers, machine breakdown, weather effects, accidents, unstable staking positions, and cutting and bending activities have all been identified as major sources of waste generation at the precast plants studied. The waste generation rate in the prefabrication is around 2% by weight or lower. It can be generally concluded that the overall waste generation of prefabrication is found to be much lower than that ofconventional construction. Finally, this study demonstrated how waste is managed in accordance with the material designated for each plant visited. This study can provide valuable data on waste management assessment in order to improve our understanding of construction waste in the precast concrete manufacturing industry.
