The construction and demolition (C&D) waste stream is the main source of solid waste in Australia. While there is a strong circularity drive in Australia’s and state/territory governments’ waste regulatory framework, clear guidelines for C&D waste management are yet to be developed for the built environment sector in Australia. This study proposes a suite of construction industry-specific guidelines for achieving circular economy (CE) goals by reviewing issues related to “Design for Zero Waste” (DfZW) and “Design for Recycling” (DfR). To do so, this study explores the current CE practices in construction and infrastructure projects in both global and Australian contexts through a systematic literature review. In addition, barriers and enablers of CE in the built environment were identified. This study provides a list of guidelines that can help industry practitioners achieve CE in the construction sector in Australia. These guidelines draw on the main themes identified through the literature review: circularity practices, resource management, innovation, and optimisation. Thus, this study bridges the gap between theory and practice by offering clear, circular guidelines for designing out C&D waste in Australia. The proposed guidelines enable industry practitioners to keep products and materials in use for a longer period and develop strategies to regenerate natural systems. Future research should focus on several aspects, including measuring emissions reductions linked to the strategies shown in the proposed guidelines.

In 2018–2019, 85% of discarded plastics were landfilled in Australia. In Western Australia (WA), only 5.6% of plastics were recovered for reprocessing. With several Asian Countries imposing import restrictions, which were the prime destination for recyclables from Australia, the whole scenario for the waste industry has changed. Australia has now adopted export bans for recyclables, including plastics. WA is at a fork in the road; WA needs to rethink its relationship with plastic materials. This study explores how to create local markets for recycled plastics underpinning circular principles. The study examines barriers and drivers to enable markets for recycled plastics in WA through questionnaires, surveys, and interviews with relevant stakeholders. Poor source separation, low and inconsistent plastic waste feedstock, and virgin plastic competition are some of the challenges, while new investments in recycling infrastructure, WA’s take-back scheme for beverage containers and circularity frameworks are drivers. This study concludes that a modulated fee-based product stewardship model focused on product design, along with strategies such as green procurement and landfill management modifications would promote a circular plastic waste economy in WA. This can create markets for secondary recycled plastics, minimize the over-reliance on fossil fuels and prevent plastics from leaking into ecosystems.
