While the increasing rate of urbanisation is a critical concern for socio-environmental reasons, this also leads to more extraction of natural raw materials and the generation of significant quantities of construction and demolition (C&D) waste. Although the use of recycled C&D waste products is technically feasible and regulated, and positive application examples are evident, it is still unclear how to engage key stakeholders to leverage this opportunity in construction projects. Previous research has shown that there is some level of resistance to the reuse of recycled C&D waste products in construction projects. This highlights a critical need to identify the roles of key stakeholders and the barriers they face when using recycled C&D materials. This paper therefore investigates the type of stakeholders influencing the use of recycled C&D waste products and the main factors affecting stakeholders’ decisions to use recycled C&D waste products through a systematic literature review. The authors present an emergent enablers and barriers for recycled C&D waste products model and provide commentary on how stakeholders’ perceptions, decision and behaviour influence the use of recycled C&D waste products. The authors also contribute to the body of knowledge with insights into the factors that various stakeholders believe influence the market for recycled C&D waste products and provides a reference point for authorities to consider these behavioural insights for policy reform.

With increased construction activities in capital cities of Australia, the sustainable management of construction and demolition (C&D) has become an important item in the federal and state government agendas. According to the universally accepted concept of waste hierarchy waste disposal is the worst preferred waste management option due to environmental issues. Currently, in most Australian jurisdictions, a landfill levy is applied to discourage waste disposal and to further encourage waste recovery. However, there is an ongoing debate as to whether the levy regime could achieve the desired outcome. Therefore, this study, funded by the Australian Sustainable Built Environment National Research Centre, explored the effectiveness of the current landfill levy across Australian jurisdictions. The paper presents the findings of this study that were obtained from a questionnaire survey aiming to capture the main C&D waste management stakeholders on landfill taxing imposition in Australia. The study collected 132 responses from professionals in the construction industry and other industries dealing with C&D waste management and resource recovery. The results demonstrated that those who believed in market incentive approaches outweigh people that were in favour of pecuniary impost approach. Among those who favoured pecuniary imposts, almost 90% of participants agreed with the effectiveness of landfill levies in any waste management system. Other results provided a useful insight into the actual implications of the current levy scheme. It is expected that the findings in this study contribute to developing sound policies that provide a level field for all key stakeholders and to ensure that resource recovery is further encouraged.

In Australia, construction and demolition activities have substantially grown over recent decades leading to the generation of a large amount of waste. Among available options, the development of end markets for construction and demolition (C&D) waste materials is regarded as a sustainable option to tackle issues around their management. Despite the promotion of a circular economy and the existence of some trading platforms set to facilitate C&D waste exchange in Australia, no research has been conducted to understand how various key stakeholders perceive their role in the C&D waste management system. Hence, this paper aims to identify the perceptions of key Australian C&D waste stakeholders on the market development for recyclable materials. The study conducted a questionnaire survey in 2019, aiming to capture the main C&D waste stakeholders on market development. In total, 132 responses were collected, and the analytical results show that participants significantly support implementing more market incentives to reduce waste disposal. They also indicate that investment in technology and infrastructure, sustainable procurement and landfill levies are three major influential factors that have a significant impact on market development. The research findings can inform decisions and policies developed in Australia to establish end markets for C&D waste management effectively.
