Strategie innovative per la sostenibilità del settore industriale.
No full textL'industria ha un ruolo centrale da svolgere nella transizione verso la sostenibilità sociale, economica e ambientale guidata dalla Commissione europea e dal Programma delle Nazioni Unite per lo sviluppo. Nonostante un crescente interesse verso un settore industriale di qualità, affidabile, sostenibile e resiliente, le singole imprese incontrano ancora diverse barriere che ostacolano una transizione conforme ai tre pilastri della sostenibilità. Di solito vengono adottate strategie comuni, ma il raggiungimento degli ambiziosi obiettivi di sostenibilità resta ancora una sfida. Partendo da una panoramica della letteratura scientifica e delle politiche europee e internazionali, il presente lavoro mette in luce strategie alternative e innovative per promuovere un'industria sostenibile. Attraverso l'analisi di casi di studio vengono dimostrati i benefici ambientali e il miglioramento del benessere umano, con un focus sulle piccole e medie imprese spesso trascurate rispetto alle grandi aziende energivore. L'obiettivo è l'identificazione di soluzioni praticabili ed efficaci per le industrie che seguono una strategia multi-approccio a più livelli, dimostrando che agire sull'intero settore industriale può contribuire in modo significativo al raggiungimento degli obiettivi di sviluppo sostenibile. I risultati ottenuti possono aiutare i professionisti e le parti interessate a integrare pratiche sostenibili nel loro modello di gestione.Industry has a central role to play in the social, economic, and environmental sustainability transition driven by the European Commission and by the United Nations Development Programme. Despite a growing interest in moving towards a quality, reliable, sustainable, and resilient industrial sector, individual firms still encounter several barriers that hamper a transition compliant with the three pillars of sustainability. Common strategies are usually adopted but reaching the ambitious sustainability target levels still remains a challenge. Starting from an overview of the scientific literature and of European and International policies, the present works highlights alternative and innovative strategies for promoting a sustainable industry. Through the analysis of case studies environmental benefits and human well-being improvements are demonstrated, with a focus on small and medium-sized enterprises often overlooked compared to energy-intensive and large companies. The objective is the identification of viable and effective solutions for industries following a multi-approach strategy at several levels, showing that acting on the overall industrial sector can significantly contribute on achieving the Sustainable Development Goals. The obtained results can help practitioners and stakeholders to integrate sustainable practices into their management model
Analisi del ciclo di vita della riqualificazione dell’ex dormitorio nord-est del Forte di Sant’Andrea a Venezia
No full textIl Forte di Sant’Andrea a Venezia è una fortezza edificata alla metà del ’500 sui resti di precedenti opere difensive ormai in rovina, parte del sistema difensivo della laguna di Venezia. Il progetto si deve all’architetto veronese Michele Sanmicheli incaricato dal governo veneziano di salvaguardare l’accesso dal mare ritenuto più pericoloso, sbarrando il passo, con le artiglierie, a un eventuale flotta nemica. Il forte è situato sull'omonima Isola di Sant'Andrea e consta di un corpo centrale, costruito sui resti dell’originario torrione quattrocentesco, e di un bastione esterno alla base del quale erano poste le batterie. Le aperture nel bastione, di forma rettangolare, erano poste quasi a pelo d’acqua per poter spazzare con il tiro l’orizzonte e colpire quanto più possibile vicino alla linea di galleggiamento i vascelli nemici.
La valutazione finale del danno, effettuata con diversi metodi, è qui riportata in funzione delle diverse categorie considerate dal metodo IMPACT 2002+ opportunamente modificato per garantire una maggiore rappresentatività del sistema studiato. In particolare è stata aggiunto il cadmio, il litio, il bromo e l’acqua nella categoria d’impatto Estrazione dei Minerali. Nell’utilizzo del territorio è stata aggiunta la fase di trasformazione ed è stata introdotta la categoria di danno Scorie Radioattive. Inoltre, nel metodo, sono stati introdotti alcuni indicatori culturali allo scopo di considerare i vantaggi che possono provenire dalla riqualificazione di un edificio, come: la Funzione attuale dell’edificio, l’Età dell’edificio, la Testimonianza storica, il Valore estetico e la Funzione dell’edificio nella storia.
L’analisi dei risultati ha mostrato che il danno ambientale totale vale 1428.9 Pt.
Analisi delle fasi di vita dell’edificio: Il danno totale incide sulla funzione sociale per l’-1.53%, la fase di produzione e manutenzione per il 13.88%, la fase d’uso per il 84.58% e la fase di fine vita per il 3.07%. In particolare nella fase d’uso il danno è dovuto per il 18.15% al processo per l’elettricità per la strumentazione, per il 31.18% al processo per l’elettricità per l’illuminazione, per il 17.29% al processo per l’elettricità per i sistemi ausiliari, per il 7.65% per il processo per l’elettricità per il raffrescamento
Recupero sostenibile di un edificio storico dell’area pedemontana etnea con il Metodo LCA
No full textIn this study, an exploration on the analysis of the life cycle for assessing the environmental, economic and social impact in the activity of recovery, restoration and valorisation of Cultural Heritage was proposed. The methodology for this sector is highly innovative, especially in its interdisciplinary approach, through the use of different technical, historical and economic skills which can provide the tools for the preparation of a management plan according to the logic of the life cycle. The analysis protocol is applied to the case of recovery and restoration processes and then outlining the salient features of what may become a model of Cultural Heritage Life Cycle Management (CH-LCM)
Life Cycle Thinking (LCT) applied to residential heat pump systems: A critical review
No full textHeat pump technology is widely considered to be one of the promising opportunities for energy-efficient and low-carbon solutions for buildings and construction. However, sustainability is not always an intrinsic feature of all heat pumps. According to the Life Cycle Thinking approach, to assess the complete sustainability of a technology, a direct evaluation of the environmental, economic and social aspects over the entire life cycle is needed. Due to the growing interest in this technology, the present review summarizes the existing contributions on the sustainability of heat pump systems for residential heating and cooling using the Life Cycle environmental and Social Assessment and Life Cycle Costing. The main results are highlighted, then the data input, methodological assumptions and evaluation criteria are analyzed. The study reveals how to improve the sustainability of HP devices from a life cycle thinking approach
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Circularity Performances of the Production of a Cement Mortar Reinforced with Recycled Synthetic Fibers
Full text linkForced by environmental implications and by legislation requirements, the cement sector is moving towards more circular economy practices, with the primary aim to enhance the sector sustainability. This commitment translates into product technology innovation, but also into innovative development perspectives for the industries involved in the supply chain. Moreover, dealing with recycled materials can modify the interaction among stakeholders from a conventional supply chain to an industrial symbiosis approach, where companies mutually exchange products and by-products into circular interactions. The purpose of this article is to investigate the circularity performances deriving from the production of a cement mortar reinforced with recycled synthetic fibers coming from artificial turf carpets. From the collection of artificial turf carpets at the end-of-life stage it is possible to recover several materials: plastic fibers used in the cement mortar, and in addition, silica sand, rubber, and bituminous membrane. The production of the innovative reinforced cement mortar leads to the connection between industries belonging to different sectors and consequently to uneven economic and environmental implications. Starting from the available literature, this study aims at evaluating the circularity potential of the unusual interactions among companies to support the development of an effective strategy, reducing environmental and economic pressures
