In this chapter, the understanding of circularity goes beyond material resource management, deepening the spatial implications of a more circular management and use of wastescapes, investigated at the urban and metropolitan scale.Besides the health (care) related challenges presented by the current outbreak of the COVID-19 pandemic, additional ones related to our living environment have been—and will continue to be—an urgent call for academic researchers, designers and policymakers to find (eco)innovative solutions and strategies for enhancing the quality of life of all and the availability of more and more safe public (open) spaces and facilities to sustain this. In this situation, the spaces most at risk of urban and peri-urban areas could be found in the unresolved places which are defined as wastescapes, since they are in general still poorly used and valued. Building on the European H2020 research project REPAiR, the definition of wastescapes, provided in this study, builds upon work for two main cases: the metropolitan areas of Amsterdam (The Netherlands) and Naples (Italy). Wastescapes are discarded territories, however, they can also be understood as opportunities to realize regenerative concepts and support strategies related to environmental, spatial and social challenges of the territories and their surroundings. Core is then to improve the socio-ecological values of such territories. Wastescapes are different case by case, being affected by site-specific challenges and characterized by high complexity. The research presented in this chapter shows that the route towards a Circular Economy requires the consideration of wastescapes as ‘spatial resources’ important to be included in strategies of transition. It represents a fundamental step to overcome problems related to both resource (and land) scarcity, land use in general and spatial fragmentation, while providing opportunities to include through eco-innovative services other values than just the monetary ones to society. The spatial regeneration of wastescapes in the built environment involves a re-thinking of the structure of these areas in a larger (metropolitan) context. Within such metropolitan settings, in particular peri-urban territories, also referred to as the areas in-between urban and rural landscapes, are most affected and characterized by this problem of wastescapes.
