Abstract
Construction industry is continuing to be one of the principle drivers of development in Malaysia. Malaysian construction sector plays an importance role in increasing income for the country and providing job
opportunities. The rapid development in Malaysia has increased the demand of concrete for construction purposes and on the other hand the concrete waste is also increasing every year and it has been pointed out as
the most generated waste from construction industry. Concrete wastes are having the huge component size and harm to the environment. Meanwhile, the increasing of concrete wastes has created the landfilling issue.
Malaysia is having limited landfill areas and those concrete wastes are rapidly fill up the landfill and caused the saturation of landfills. Besides, Malaysia is a developing country and there is less of knowledge and skill
of waste management. The lack of efficient and proper waste management technologies has caused the increasing of construction cost and waste of resources. In fact, conduct a proper and efficiency concrete waste management technology is the long-term solution to saving the construction costs, prevent the depletion of natural aggregates resources, solve the landfills problem and protect the natural environment. Therefore, the aim of this research paper is to investigate and conclude out a proper concrete waste management which could improve the current concrete waste management in Malaysia. A literature review from related books, conferences papers and journal articles was carried out. The findings show that the awareness of Malaysian construction industry regarding waste management is still generally low and there is very little information on the study of current concrete waste management in Malaysia. Hence, an investigation is needed to find out the current situation of concrete waste management in Malaysia and along with find out an efficient waste management practices. Questionnaire approach has been adapted to achieve out the research aim and objectives. From the data obtained, current circumstances of construction and demolition waste management in Malaysia, level of awareness of construction practitioner and the best
alternative concrete waste management practice have been found. It found that concrete caused most construction problem in Malaysia. Other than that, it found that Malaysian construction practitioner has high awareness level on C&D waste management, and they are having high expectation and willingness on improve the current C&D waste management situation in Malaysia.
