Improving sustainability in communities: Linking the local scale to the concept of sustainable development
No full textSustainability challenges can be faced at local, urban and national scale leading to diverse initiatives constrained mainly by economic and cultural limits. Of these three levels, the local has the advantage of being the closest to people and therefore encouraging active collaboration. The aim of this research is to realize a path towards community sustainability based on maturity assessment. Our intent is to explore how to link the local scale to the concept of sustainable development and how to achieve a dynamic evaluation and management of sustainability. We obtain a maturity-based sustainability assessment through a framework based on territorial context analysis (scoping phase), maturity assessment (design phase) and case study application (evaluation phase). A small community located in Italy was selected for our case study. This research proposes a sustainability maturity assessment that embraces all the plans, programmes and initiatives needed to define improvement goals and strategies covering all aspects of sustainability. It enables the dynamic management of sustainability at the local level and allows communities to define sustainability strategies in which maturity assessment plays a key role by linking the existing situation with improved future situations
Il recupero dei rifiuti tessili per la circular economy
No full textLa domanda globale di prodotti tessili è in costante aumento (The Fiber Year Consulting, 2015; Oerlikon, 2010), una tendenza che probabilmente continuerà. Nel frattempo, l’industria tessile sta affrontando enormi sfide ambientali e di risorse

No full textAllocation strategies in comparative life cycle assessment for recycling: Considerations from case studies
No full textThe objective of this research is to verify whether an end-of-life allocation strategy can affect the choice between two products or two processes. This study evaluates whether a comparison between two products/ processes that is obtained by applying the cut-off (CO) approach and substitution method (Sub) can cause a sign reversal for products/processes with different recyclability features. The main intent is to provide a clear picture for Life Cycle Assessment practitioners, who analyze recycling systems and would benefit by knowing whether an end-of-life allocation strategy can affect the preference ranking between products or processes. Two comparative case studies were developed using primary data. The case studies were very different because they referred to different sectors. In the first case study, the analyzed subjects were two plastic products; in the second case study, the analyzed subjects were an incineration line under design and an incineration line under operative conditions. For the first case study, the allocation strategies were implemented in the modeling of the burdens of input waste and end-of-life disposal. For the second case study, the allocation strategies were implemented in the modeling of input waste; in the burdens of end-of-life disposal of slag, ashes and dust; in the recovery of construction materials; and in energy recovery. To confirm the main findings of the first and second cases, an additional case was simulated by combining the first and second cases. The results obtained in the two case studies and in the combined case indicate that comparisons between the analyzed products/processes are only marginally affected by the applied end-of-life allocation strategies and are consistent with both the allocation strategies for almost all of the analyzed impact categories
