This systematic review synthesises findings from 60 studies on waste-to-resource innovations across construction and household contexts. Although the existing literature predominantly addresses construction and demolition waste, this review foregrounds household operational waste, an area that remains insufficiently explored despite its importance for everyday resource recovery. The analysis examines how materials generated through routine use, maintenance, and minor renovation activities can be captured and redirected into productive resource streams, with particular attention to governance mechanisms such as Extended Producer Responsibility (EPR). The findings indicate that effective waste-to-resource systems depend on coherent regulatory frameworks and enforcement, economic incentives, enabling technologies, community engagement, and product design that facilitates reuse and disassembly. Key barriers include low public awareness, fragmented supply chains, high recovery costs, weak compliance mechanisms, and materials that are difficult to separate. The review concludes that improving waste-to-resource outcomes in the built environment requires coordinated action among producers, households, local authorities, and technology providers, and it articulates policy-relevant and community-oriented pathways to support more effective resource recovery systems.</jats:p>Copyright: © 2026 by the authors.
