As sustainability expectations grow, organisations and governments are increasingly exploring circular economy models that reduce waste and extend product lifecycles. While systems such as deposit return schemes for bottles are becoming more familiar, many everyday products – clothing, electronics, household items, and others – still lack clear, trusted pathways for reuse, return or responsible disposal. This creates challenges around waste reduction, accountability, consumer behaviour and policy implementation. This project invites to explore how circular systems could be designed for everyday products at scale. How might principles such as extended producer responsibility (EPR), digital product passports or return-and-reward models be applied beyond traditional recycling schemes? Could digital tools, service design or physical infrastructure help make participation in circular systems simple, transparent and accessible for users? When considering the roles of consumers, producers, retailers, communities, and policymakers, what information needs to travel with a product throughout its lifecycle? How can trust, transparency and usability be embedded into circular systems? What incentives or experiences might encourage widespread participation without creating friction or confusion? The outcomes of this project could inform future approaches to sustainability, innovation and policy design, with relevance to local-level environmental ambitions and broader global efforts to transition toward a circular economy.
