Factors affecting construction waste management streams in Australia

Construction and demolition waste management in Australia: A mini-review

“…Wu et al (2020) performed an exploratory study of waste mobility in Australia and found that cross-border waste mobility was driven by the availability of local C&D waste recycling facilities or landfill sites, inconsistencies in landfill levies between states, and the waste recycling market. Newaz et al (2020) indicated that recycling opportunities varied with locations and cross-regional waste movement could be attributed to the inconsistent policies in NSW, Queensland, and Victoria.…”

“…Thus, some masonry waste generated in ACT was sent to NSW for landfilling because of shorter transportation distance, lower transportation cost and no landfill levy, while NSW also transported waste to Queensland, ACT and Victoria (Wu et al, 2020). Before landfill levy was imposed in Queensland, NSW transported a huge amount of waste to Queensland (Newaz et al, 2020).…”

“…Previous empirical studies in Australia have revealed the importance of training and education for C&D WM. For instance, Lingard et al (2000) suggested that training should be provided for site managers in order to motivate them to prioritize WM; Udawatta et al (2015b) indicated that most interviewees highlighted the importance of training and education for all stakeholders to enhance C&D WM performance; and Newaz et al (2020) interviewed 19 practitioners in NSW and found that knowledge, experience, and training of site operatives were one of the key factors influencing C&D WM. Park and Tucker (2017) argued that higher education of architects and continuous professional development programs could help designers to adopt low-waste design and that training should be provided for staff at all levels of contractors and subcontractors, regardless of company size.…”

“…On-site waste sorting and treatment could be performed to increase reuse and recycling and reduce transportation costs but require sufficient site spaces (Li and Yang, 2014). In NSW, Newaz et al (2020) found that contractors preferred to outsource WM responsibilities and focused on their core business. In addition, effective site management contributes to C&D waste reduction (Kabirifar et al, 2020), including material management, regular site inspection, rework minimization, and site space planning.…”

“…In addition, effective site management contributes to C&D waste reduction (Kabirifar et al, 2020), including material management, regular site inspection, rework minimization, and site space planning. Site space planning makes sure that WM processes do not interfere with other construction activities in a constrained site space and enables on-site materials to avoid contamination or mixture (Newaz et al, 2020). Also, Udawatta et al (2015b) found that construction technologies to minimize waste was the top solution for C&D WM.…”
