“…Lately, research into waste efficient design and impacts of design on waste is also gaining popularity (cf. Udawatta et al, 2015;Osmani, 2012;Wang et al, 2015;Osmani et al, 2008). However, despite the understanding that materials procurement process contributes to construction waste generation (Wang et al, 2008;Greenwood, 2003;Lu et al, 2011), strategies for enhancing waste efficient procurement remained less explored.…”

Although construction waste occurs during the actual construction activities, there is an understanding that it is caused by activities and actions at design, materials procurement and construction stages of project delivery processes. This study investigates the material procurement and logistics measures for mitigating waste generated by construction activities. In a bid to explore the phenomenon from the perspectives of experts from the construction industry, this study used a combination of descriptive interpretive research and survey approach as its methodological framework.The study suggests that four features characterised waste efficient logistic and procurement process. These include suppliers' commitment to low waste measures, low waste purchase management, effective materials delivery management and waste efficient Bill of Quantity. In addition, the key requisite strategies for mitigating construction waste through materials procurement include commitment to take back scheme , procurement of waste efficient materials/technology and use of minimal packaging. The use of Just-in-Time (JIT) delivery system and prevention of over ordering are also important for mitigating waste through materials procurement processes. These implies that while the key measures are critical success factors for reducing waste through procurement process, the four established features are required of all procurement process. Measures through which the procurement process could enhance waste efficiency are further highlighted and discussed in the paper. Findings of this study could assist in understanding a set of measures that should be taken during materials procurement process, thereby corroborating waste management practices at design and construction stages of project delivery process.

“…In the United Kingdom, more than 50% of waste deposited in a typical landfill comes from construction [3][4][5], while about 70 million tons of waste arise from construction and demolition activities [6]. In Australia, about 17 million tons of waste are put into landfills each year and about 42% of waste is attributed to the construction industry [7,8] (Productivity Commission 2006, Udawatta et al 2015). In the United States of America, around 29% of solid waste is from construction [9,10].…”

Practitioners Recycling Attitude and Behaviour in the Australian Construction Industry

Construction waste management and recycling is widely discussed. However, at present there is still a significant amount of waste generated during the construction process. Considering this fact, this research aims to analyse the recycling attitudes and behaviours in the Australian construction industry. This paper investigates attitudes and behaviour towards recycling habits in construction; understands how recycling is viewed and carried out by practitioners in the industry; explains the causes of these states of mind; and formulates techniques that could be utilized to improve waste management and recycling acceptance within the industry and improve its effectiveness. Initially, the required data was collected through a questionnaire survey. Afterwards, a statistical analysis was carried out using SPSS software. It was found that the practitioners' attitude towards recycling habits are positive; however, their behaviour is not as strong as it should be. This means that the industry is aware and concerned about recycling in construction and willing to improve the environment by developing recycling habits. Recommendations to improve attitudes and behaviour towards recycling habits are also suggested, such as legislation and market driven developments, improvements of waste management methods, provisions in work method statements, sharing research and applications in sub-industries and developing communication.

“…Additionally, the lack of construction waste management also can contributes negative impact to environmental issues, social and economy [3][4] [12]. Unsystematic construction waste management also can contribute to the health and safety issue of construction workers [13].…”

Abstract. Development of the construction industry generated construction waste which can contribute towards environmental issues. Weaknesses of compliance in construction waste management especially in construction site have also contributed to the big issues of waste generated in landfills and illegal dumping area. This gives sign that construction projects are needed a systematic construction waste management. To date, a comprehensive criteria of construction waste management, particularly for construction project in developing countries such as Malaysia is still not systematically defined. Therefore, construction waste management needs further investigation. This paper aims to explain a concept model for systematic construction waste management in the Malaysian construction industry. The methodology of this paper is through literature and previous research focusing on current practices of construction waste management, the barriers of construction waste management implementation and the additional factor for implementing systematic construction waste management in order to develop a conceptual model. Findings from this study will help to find out the elements required to implement systematic construction waste management in Malaysian construction industry. This action seems significant to the participants in prioritizing construction waste management more systematically. The implementation also will increase the awareness and better understanding of the construction players of the importance of construction waste management in construction projects.
