摘要

Building and construction projects are being completed at an unprecedented rate globally. Unsurprisingly, this level of construction generates a substantial amount of waste. Despite increases in the rate of recycling, products with recycled content are underutilised in construction projects. It is well-documented that the use of products with recycled content may increase carbon emissions in construction projects under certain conditions. These emissions are the direct result of the energy necessary for waste resource management, recycling, and transportation. To address this issue, the concept of nature-based solutions can provide an innovative approach to offset carbon emissions caused by recycling and related activities. The aim of this research is to delve into the relationship between products with recycled content and nature-based solutions by conducting a brief analysis of the existing literature. The review has highlighted six application areas where these concepts have been reported to be applicable. Furthermore, this study proposes a practical framework for the adoption of nature-based solutions + products with recycled content in the building and construction sector. The findings from this review will serve as a foundation for developing a framework that can guide policy development and industry practices in promoting optimised utilisation of products with recycled content, while simultaneously striving towards achieving net-zero emissions.
