Electric mobility in Sicily: An application to a historical archaeological site
2016
Transports should be a key focus in the close future for decarbonization efforts, if the optimistic climate change mitigation objectives to be reached by 2050 on a global scale are to be met. Choosing an emblematic and historical location in the center of Sicily as object of the study, the potential for decarbonization and the reduction of the energy and environmental impacts in the site for electric mobility is assessed, by considering electric mobility scenarios based on different shares of electricity generated through renewable energy technologies. The analysis is performed by means of a life-cycle approach, through the use of the Life Cycle Assessment methodology. A parametric analysis…
Second life employment of a traction battery for load match optimisation of a residential building: Life cycle and operation applications
The increasing use of renewable energy technologies for the electricity generation in buildings will require a growing number of energy storage systems (ESSs) in the next years in order to reduce the mismatch between the highly variable on-site electricity generation and the building load. Retired electric vehicle batteries (EVBs), before recycling, can be used for this purpose, considering that they have about 80% of the original energy capacity. In this context, the study aims at examining an ESS made by retired EVBs, in order to identify its optimal size for reducing the mismatch in a net zero energy building equipped with a photovoltaic plant and to assess the life cycle energy and envi…
Life-Cycle Assessment Applied to Future Scenarios of Electricity Generation in Sicily
2018
Fighting global warming and increasing the energy security are some of the most relevant objectives of the European energy policy. Thus, defining potential low carbon pathways for the energy sector is of paramount importance in order to identify strategies with the lowest impact on climate. This paper presents an overview of environmental assessment of future electricity scenarios in Sicily (Italy), for 2020 and 2030, characterized by a high exploitation of renewable energy sources. Authors apply the Life Cycle Assessment methodology, according to the standard of the ISO 14040 series, in order to evaluate the environmental impacts of electricity generation in the future scenarios in compari…
Sustainability Assessment of Second Life Application of Automotive Batteries (SASLAB) - JRC Exploratory Research (2016-2017) Final technical report A…
2018
The fast increase of the electrified vehicles market will translate into an increase of waste batteries after their use in electrified vehicles (xEV). Once collected, batteries are usually recycled; however, their residual capacity (typically varying between 70% and 80% of the initial capacity) could be used in other applications before recycling. The interest in this topic of repurposing xEV batteries is currently high, as can be proven by numerous industrial initiatives by various types of stakeholders along the value chain of xEV batteries and by policy activities related to waste xEV batteries. SASLAB (Sustainability Assessment of Second Life Application of Automotive Batteries), an exp…
Passive components for reducing environmental impacts of buildings:analysis of an experimental green roof
2020
The reduction of the environmental impacts related to the building sector is a matter of outmost importance concerning the sustainable utilization of resources related to human activities. Such sector is in fact responsible for about 40% of both release of pollutants in the atmosphere and energy consumption. When trying to reduce buildings’ environmental impacts, as well as to limit their energy consumption, building envelope passive systems can be used. Amongst these, green roofs have been gaining global attention due to their benefits in terms of resilience and sustainability, in order to mitigate the unfavourable urbanization effects. Research on the green roof has been indeed increasing…

LIFE CYCLE ASSESSMENT-DRIVEN SELECTION OF INDUSTRIAL ECOLOGY STRATEGIES
2010
The paper presents an application of the Life-Cycle Assessment (LCA) to the planning and environmental management of an ‘‘eco-industrial cluster.’’ A feasibility study of industrial symbiosis in southern Italy is carried out, where interlinked companies share subproducts and scraps, services, structures, and plants to reduce the related environmental impact. In particular, the research focuses on new recycling solutions to create open recycling loops in which plastic subproducts and scraps are transferred to external production systems. The main environmental benefits are the reduction of resource depletion, air emissions, and landfilled wastes. The proposed strategies are also economically…
La Life Cycle Assessment come strumento di supporto per le piccole e medie imprese: un caso studio siciliano
2014
L’Unione Europea mira ad orientare il mercato verso una crescente domanda di prodotti e servizi ecoefficienti ed eco-sostenibili. Le PMI, per essere competitive sul mercato, hanno la necessità di superare il gap tecnologico e di competenze che spesso le caratterizza ed avviare processi produttivi eco-orientati. In tale contesto nasce il Centro di Ricerca Italo-Maltese per la Sostenibilità Ambientale e le Fonti Rinnovabili (CRIM-SAFRI), che si propone di offrire una significativa opportunità di crescita e sviluppo per il tessuto produttivo dell’area del Mediterraneo, contribuire a ridurre i consumi energetici, le emissioni di gas serra e di altre sostanze inquinanti connessi ai processi prod…
Impatti energetico-ambientali connessi alla produzione di energia elettrica in Sicilia
2014
Negli ultimi anni l’attenzione verso le problematiche connesse al cambiamento climatico e all’approvvigionamento energetico è diventata sempre più rilevante. L’Unione Europea ha approvato il “pacchetto clima-energia” che mira, entro il 2030, a ridurre le emissioni di gas ad effetto serra del 40% rispetto al 1990 e ad incrementare la quota di energia prodotta da fonti rinnovabili almeno al 27%. Per iniziare a stimare i benefici indotti dall’incremento della produzione di elettricità da fonti rinnovabili, nel presente lavoro vengono stimati gli impatti energetico-ambientali connessi alla produzione di 1 kWh di energia elettrica in Sicilia nell’arco temporale 2000 – 2011, tramite l’applicazion…
La LCA di sistemi solari per il condizionamento
2017
L'edilizia è uno dei settori più rilevanti in termini di produzione di ricchezza e di occupazione, ma è anche responsabile di significati consumi di risorse naturali e impatti ambientali. SI stima, infatti, che nell'Unione Europea l'edilizia sia responsabile del 50/60 % del consumo di risorse naturali, e tali percentuali difficilmente decresceranno senza l'avvio di strategie e azioni orientate alla riduzione dei consumi di combustibili fossili e all'aumento dell'impiego delle risorse rinnovabili.
