Progettazione tecnologica della città e paesaggio urbano nella gestione dei rifiuti. Circolarità dei processi per un nuovo metabolismo

Abstract

When considering the problems due to the increase of Municipal Solid Waste and its disposal, it becomes clear that the latest European directives have drawn greater attention on this issue directing disposal strategies towards circular economy and zero impact. Research innovation mainly lies in the strategic and methodological aspects outlining a trend reversal by turning technological innovations into effective actions and solutions that are compatible with urban and environmental heritage so to allow their preservation and recovery as well as their implementation. Starting from the discretization of the logistic problem and from the recovery and technological retrofitting requirements of urban services in open spaces and buildings - with the instrumental use of well-known innovative technologies - this study proposes practical actions characterised by administrative, technical and economic feasibility. Such actions can be achieved through accurate sustainable and innovative regeneration interventions on infrastructure and spaces of existing towns as well as through opportunities of social participation and development building networks with the public administration, enterprises, the service industry, and users. In an age of huge crisis of resources, and at the same time of strong environmental awareness, where the waste issue represents a pressing problem, often an emergency, it is still possible to collect cash flows to solve the problem offering new opportunities for the town physical recovery and for social and occupational development, with all the consequent advantages. Like in the most renowned international cases, those strategies can address the service issue and increase their positive effects in terms of residential, tourism and financial attractiveness. At this point, it is clear that as far as waste disposal is concerned, communities must be self-sufficient; it is necessary to: increase the value of waste through the production of secondary raw materials and energy; create intervention models and strategies that can be reproducible and/or easy to re-modulate; underline the interdependence between sustainable development, safeguard of resources and employment.
