Energy assessment of a dish-Stirling system powering a reverse osmosis plant for seawater desalination

2022

Water scarcity in many regions of the world and the global demographic growth make the desalination of seawater and/or brackish an effective solution to meet the growing demand for freshwater. Nowadays, reverse osmosis has the largest share of the global installed desalination capacity. The impelling need to reduce greenhouse gas emissions has been pushing the search for sustainable technologies to produce the electricity needed to power reverse osmosis plants. Among solar technologies, little attention has been paid to the possibility of powering reverse osmosis with electricity from the dish-Stirling concentrator. To fill this knowledge gap, this paper assesses the energy-saving potential…

Combined Oxidation-Gasification system for waste treatment with supercritical water: LCA and performance analysis

2020

In this study the environmental performance of a first of a kind integrated process based on supercritical water gasification and supercritical water oxidation, was evaluated using Life Cycle Assessment (LCA). The process was applied to the treatment of carbon black and used oil as model waste. Mass and energy balances were performed using Aspen Plus, and the environmental assessment was carried out through SimaPro. For the analysis was chosen a “From cradle to grave” approach, considering impact categories like climate change, ozone depletion, human toxicity, particulate matter, land use, resource depletion and others relevant indicators. The environmental profile of SCW-GcO process was co…

Life Cycle Assessment and eco-design of building materials: the case study of a Sicilian cement plaster

2015

Buildings in the European Union (EU) account for the largest share of the total EU final energy consumption (42%), and greenhouse gas emissions (35%). Therefore, the reduction of energy use, the development of quality-oriented processes and the improvement of energy performance in the building sector are important measures needed to reduce greenhouse gas emissions and the energy dependency of the European Union from foreign countries. In this context, it is necessary to develop sustainable building products, with low energy and environmental impacts during their life cycle, from the extraction of raw material to the manufacturing, use and end-of-life. The main goal of the study is to define…

Life Cycle Assessment della filiera di trattamento di biomasse residuali: un caso studio

2022

Il presente lavoro descrive i risultati dell’analisi di Life Cycle Assessement, sviluppata in accordo agli standard della serie ISO 14040, di un processo di trattamento di biomasse residuali di origine forestale da impiegare per la successiva valorizzazione energetica. L’analisi è riferita ad 1 kg di cippato, selezionato come unità funzionale. I confini del sistema hanno incluso le fasi di raccolta della biomassa residuale (strascico indiretto e diretto), cippatura della biomassa, raccolta e trasporto del cippato all’impianto di valorizzazione energetica. I risultati dello studio mostrano che la filiera in esame, con riferimento all’unità funzionale, causa un impatto di 0,027 kg CO2eq e det…

Reuse of electric vehicle batteries in a residential stationary application: an integrated load match analysis and life cycle assessment approach

LIFE CYCLE ASSESSMENT OF SOLAR COMMUNITIES: A SCENARIO ANALYSIS

The study proposes the comparisonof the life cycle performances of two different energy systems aimed at covering the needs of a large mixed-mode community, in Calgary (Canada). The two systems investigated are a“conventional” one, using heat pumps for heating, cooling and domestic hot water, and another one widely deploying solar thermal panels as well as a district heating infrastructure and a borehole seasonal thermal storage. The analysis is based on the LifeCycle Assessment (LCA) methodology and includes the stages of raw materials and energy supply, system manufacturing, use stage of the systems, generation and use of energy on-site, maintenance and components’ substitution, and explo…

Life cycle analysis of innovative building materials based on circular coffee ground supply chain

2022

The construction sector is widely recognized as one of the most polluting mainly due to its intensive exploitation of natural resources and large energy consumption to produce traditional building materials. In the last years, alternative building materials have been developed with the aim to reduce the environmental burden of this sector. In particular, the use of geopolymer mortars as alternative cementitious materials is gaining increasing acceptance among scientists. Numerous laboratory studies demonstrate their suitability for construction applications, highlighting the potential environmental benefits that can be obtained from their large-scale production. This study aims to perform a…

Effect of Vibration on the Quality of Strawberry Fruits Caused by Simulated Transport

2016

Mechanical damage of agricultural products is one of the main problems in the harvest and postharvest chain due to the large economic loss that the shelf life reduction could generate. Measurements of change in the chemical components of highly perishable products and microbial growth under different static and dynamic loads is the first step in the development of intelligent logistic units that could help in predicting the residual shelf life in order to minimize losses along the supply chain. In our research, the effects of vibration along the supply chain of a case study were analyzed on strawberry (Fragaria x ananassa) and woodland strawberry (Fragaria vesca) in terms of microbiological…
