Drosscapes and new urban metabolism. New strategies and tools for sustainable and resilient regeneration

Starting from the analysis of the complex socio-political framework and from some design and regulatory references that integrate in planning, a new model of ecologically oriented city, the contribution identifies in the enhancement of drosscapes as a new design metaphor that can improve biodiversity, encourage ecological and energy transition, restore, with natural solutions, the quality of air environmental matrices, water and soil, triggering a new urban metabolism. Through the application of an iterative and interscalar methodology articulated in levels and phases to a study area lying in the Roman suburbs and subjected to the procedure of the urban project, the contribution proposes a reflection on the need to implement design strategies capable of counteracting dissipative dynamics, building resilient landscapes, sustainable energy cycles within ecological regeneration scenarios, morphological reconfiguration of urban fabrics and public spaces related to the promotion of an efficient city, smart and green. In this perspective, it highlights the potential and limits of the proposed experimentation, both in terms of the quality and innovativeness of the design solutions, and in terms of possible evolutionary lines that could raise the levels of settlement and environmental quality, of social inclusion and economic growth.
