Circular Economy in Cities: Framework Development & Porto (Portugal) Case Study Analysis
Circular Economy (CE) is a recent concept that is gaining strength worldwide due to China's implementation and the European Union (EU) contribution. It is seen as the alternative to a wasteful linear economic system, with the aim to keep products at higher value and for longer time. Together with it, there is a trend of urbanization, with already 50% of the population living in cities and with expectations of this share to rise to 70%. This work main goal is to understand the role of cities in CE implementation and its monitorization. To do so one started by understanding the key concepts and state-of-the-art behaviours and technologies associated to CE, alongside an understanding of its history. Furthermore, one shifted this definition to an urban context, understanding how a circular city should look like and how and where it could leverage circularity, by also benefiting from it. Finally, a framework for the city analysis was developed, together with a Case Study relating Porto, Portugal, analysing this city from a representative perspective, while taking conclusions from the respective results. The framework is based in CE key concepts, as transparency, modularity and flexibility. It allows the definition of relevant sectors in the city, its evaluation and the interaction between them, aiming for a holistic approach. Major conclusions were taken from this work. First, Porto was considered a city with potential to be circular. Moreover, it has the opportunity in leading, together with cities as Amsterdam, Barcelona and Glasgow, the urban transition towards CE. Second, the relevant indicators for CE are yet to be defined, with this responsibility laying between the EU and the Ellen MacArthur Foundation (EMF), and, besides evaluating circularity in different levels and sectors, shall also be realistic, concerning data that can be collected today, recommending meaningful data that shall be collected in the near future. Furthermore, a multi-criteria analysis can be later included, connecting the different ...
