IDEAL-CITIES: A Trustworthy and Sustainable Framework for Circular Smart Cities

by Giorgos Dimitriou & Vasilis Katos

One of the main challenges of a modern smart city is to bring people together, making them ambassadors of a sustainable, restorative and regenerative way of life and expediting the shift to the Circular Economy model. A city achieving a smart city status cannot be automatically considered sustainable nor inclusive. A Sentient City achieves sustainability of the resources and inclusiveness for the people.

This paper from IDEAL CITIES, a European Union-funded project, examines how smart city technologies can promote a data-driven circular economy model. Under this framework, a city's finite resources as well as citizens will form the pool of intelligent assets in order to contribute to high utilization through crowdsourcing and real-time decision making and planning. For instance, by helping the visually impaired citizens navigate and productively enjoy their city, services becoming enabled to respond in real-time and in the most cost-effective manner by identifying and repurposing resources with a minimum effort. A data-driven sentient city will know when it has achieved its goals because it will at the same time measure one of the most important performance indicators: citizen’s happiness.

Creating A Circular Economy with Less Plastic Waste - Implications and Gaps in the International Trade of Plastic Waste

by Quinn Liu

The Basel Convention was amended in 2019 to include plastic waste as hazardous wastes with restrictions for international trade. The amendment will make global trade in plastic waste more transparent and better regulated, whilst also ensuring that its management is safer for human health and the environment. These international trade policy changes signal a transition towards a more resource efficient and circular economy, which can occur at various levels along the product value chain such as second-hand goods, end-of-life products, secondary materials or waste, as well as trade in related services. In this paper, Quinn Liu highlights gaps and opportunities in updating the existing regulatory framework and re-designing the global supply chain to transition to a sustainable circular economy.
