Title : Waste and historical city. Technological solutions for circolar management in an urban landscape
Abstract: Circular management of resource flows is an operational problem that appears with greater severity in an historical urban landscape due to the constraints generated by road fabrics and by the need to protect its values. It often happens that the degradation generated by the irresolute nature of the technical-environmental issues related to the service management, affects both the vulnerability of the historical city characters and the involvement of different actors.
Here, we present the results of a research work that, through a case study, develops the experimentation of a methodology that identifies criteria for a waste collection system planning in an urban landscape of high historical and artistic value.
The planning of the operational phase involves the installation of several devices essential for the correct management of waste collection, in terms of comfort for the user who gives the consumed material and for the administration that must dispose of it. The experimented methodology is divided into three phases: analysis, hypothesis and evaluation, each indispensable for the development of the next phase and all complementary to each other.
In its first phase, the research takes into account the current national and international state of the art with respect to waste management, leading to the selection and implementation of preferable means for a sustainable and righteous management.
The second phase features the definition of operative strategies for the management of resource flows, with the objective of regenerating and developing the local context. The investigation’s goal is achieved with the elaboration and testing of an informative system created to evaluate the success of the integration between the operative systems and the qualitative and quantitative systemic factors, typical of the environment in which the research is set.
We use a multi-criteria evaluation that is able to simultaneously consider several evaluation criteria with different dimensions, allowing us to take into account the elements of social impact that cannot be expressed in numeric terms. The impact of configured scenarios is evaluated using criteria and sub-criteria which aim to ascertain in advance if the necessary transformations for their realization can determine an alteration to the existing site and the possible degree of tolerance for their acceptability.
