Appraisal of Waste Minimization and Management in the Context of Malaysian Construction Industry

The construction industry consumes a substantial amount of raw materials in its processes and the output is obviously the product and most importantly the waste material. Other than that, the construction industry is well known as one of the worst environmental polluters. This study is to determine the use of waste minimisation technique in creating sustainable waste management in order to identify the technique which has the most capabilities to reduce on-site waste. The objective of this study is to assess the waste minimization techniques taken from the 4R concept (which includes reduce, reuse, recycle and recovery techniques) in minimizing the waste in construction waste management. The most used waste minimization technique found in the 4R concept would be waste reduction. This shows that the local construction industry has the knowledge necessary to plan out the waste management processes but the implementation is still far from satisfying. Additionally, the findings reveal that because the industry is profit-driven, construction practitioners are motivated by profit to adapt to this techniques.

Area Of Concern

Construction industry in Malaysia is growing rapidly with high demand due to vast development and urbanization. Therefore, many commercial and residential buildings are being developed. The increasing number of construction projects in Malaysia will indirectly contribute to the increase of construction waste generation. Thus, waste minimization is an important area of concern in the implementation of the construction waste management in the construction industry of Malaysia. Data collection and observations was conducted at three construction sites which adopt different type of method with different type of building and size of project in Klang Valley. The calculation of the construction waste index generated at these sites is adopted from Poon et al., (2001). Result showed that construction method, size of projects (GFA), type of building, storage method system, human error and technical problem can affect the amount of waste index (debris) and amount of wastage level generated at construction sites. Therefore waste index and wastage level can be used as operational an indicator for waste minimization of the construction activities.

Dynamics Modelling

In recent years, Malaysia has faced an intense demand for infrastructure development and the construction industry has become an integral part of transforming the country into a developed nation. Large numbers of development works are perturbing and they are subject to the improper management of construction and demolition (C&D) wastes. Lacking in methods for managing C&D wastes throughout the construction cycle has jeopardized the effort to preserve the environment. Circular economy (CE) was used as a basis to improve the C&D waste management system in Malaysia. We have developed a circularity-based planning approach to managing the wastes with an idea to maximize the resources. We collected the feedback from the construction actors in Malaysia to identify the suitable 3R principles of reduce, reuse and recycle and waste minimization strategies to be adopted throughout the construction cycle. Based on the feedbacks, we introduced a circularity-oriented framework of C&D waste management that could be applied throughout the construction cycle. Then, we tested the effectiveness of the framework by conducting a simulation process using system dynamics modelling. The results revealed that the waste generation could be significantly reduced – that indirectly mitigate the environmental impacts.

Minimization Approach

The movement towards sustainability and resiliency has become a central talking point for the Malaysian government. Waste that is immeasurably generated from the construction activities should be appropriately managed to preserve the environment. This study was conducted to assess the level of knowledge about the concept of Circular Economy (CE) as an approach for waste minimization via a survey questionnaire sent to the G7 contractors in the Klang Valley area. The ultimate version of the questionnaire consisted of 38 questions, and it was sent to 360 targeted G7 contractors. 135 questionnaires were returned with a response rate of 37.5%. The results reveal that most of the contractors were knowledgeable about the potential of the CE concept as an approach for waste minimization. Environmental sustainability would be attained when the CE concept is used to minimize the waste generated from the construction activities. The integration of adaptative reused is found to be suitable to enhance the implementation of the CE concept. The results revealed considerable potential for the CE concept to be used as a waste minimization approach in the construction industry. In this sense, the enhancement of the CE concept implementation throughout the construction cycle could set up a direction for future research.

Waste disposal has become an issue worldwide and the major cause of this issue is considered to be the construction activities producing wastes. Pakistan being the 6 most populated country in the world is considered to have a huge amount of waste due to the various construction and particularly megaprojects and this amount of construction waste is increasing consistently in the country. Pakistan produces of construction waste per year and is increasing annually by 2%. These increasing wastes and issues associated with these construction wastes lead to a crucial need for improvement of waste management practices in the construction industry of the country through various measures. Despite of the large need for waste minimization research in Pakistan, , deductive approach was used, and quantitative method was selected, the present study has used cross-sectional design. The researcher used a sample of 323 individuals and conducted a questionnaire-based study.

Reinforcement Bar

The Malaysian construction industry is responsible for producing a huge amount of structural reinforcement bar wastes which has a major impact on the environment, the society and economy. Thus, the minimization of reinforcement bar waste has become a persuasive issue in the construction industry. This paper investigates the causes of the rebar waste generation from different construction projects in Selangor, Malaysia as to determine later what are the construction waste minimization (CWM) tools and techniques currently available for the construction industry. A quantitative research approach was adopted using a survey method utilizing questionnaires. Descriptive analysis was employed to process the data for this study. Thus, this paper, explores the potential application of BIM to design out rebar waste. An in-depth literature review was conducted to provide a foundation for the study to evaluate if the use of BIM will assist as a possible platform for the reinforcement of waste minimization.
