The CIRCULAR project will investigate two case study regions: The Grand-Duchy of Luxembourg and the Swedish county of Västra Götaland. Both regions are subject to EU policies and regulation and therefore offer an opportunity for scrutinizing spatial particularities within a similar setting. The two regions also share structural similarities in their industrial past with background in traditional manufacturing and ongoing processes of restructuring their industries. Another commonality is that the regions have recently launched a variety of initiatives with the aim of fostering Circular Economy.
