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 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…
Human reliability analysis to support the development of a software project
2017
The Human Reliability Analysis (HRA) is considered as a useful tool in predicting and quantifying the occurrence of human errors during the execution of a specific task. With this recognition, the present paper firstly aims at discussing the support given by HRA methodologies to the fault risk evaluation. Then, the Technique for Human Error Rate Prediction (THERP) is suggested to evaluate the success probability of a software development project.
Combining Membrane and Zero Brine Technologies in Waste Acid Treatment for a Circular Economy in the Hot-Dip Galvanizing Industry: A Life Cycle Persp…
2023
AbstractAn innovative approach of combining membrane and zero brine technologies for a joint treatment of industrial liquid waste is investigated regarding its environmental impacts compared to the existing liquid waste treatment. The object of investigation is the generation of waste acid solution by a hot dip galvanizing plant in Sicily, Italy. The waste acid solution contains hydrochloric acid, iron and zinc, which makes it a hazardous waste according to EU classifications. Environmental impacts are studied for two scenarios in the Tecnozinco hot-dip galvanizing plant in Sicily, Italy: (i) the current process of pickling with linear disposal of waste acid and (ii) the pickling combined w…
Ottimizzazione Multi-Obiettivo delle Prestazioni Energetiche e Ambientali di un Edificio Residenziale
2019
Il presente lavoro, svolto nell’ambito dell’Annex 72 dell’International Energy Agency, descrive un approccio metodologico volto all’identificazione di interventi ottimali di ristrutturazione da effettuare sull’involucro di un edificio residenziale, permettendo di minimizzare contemporaneamente quattro funzioni obiettivo: i consumi energetici in fase d’uso, i costi d’investimento e gli impatti energetici e ambientali di ciclo di vita. L’ottimizzazione, eseguita tramite un algoritmo multi-obiettivo, ha permesso di identificare gli spessori di materiale isolante e di materiali massivi da aggiungere sul tetto e sulle pareti perimetrali dell’involucro edilizio per minimizzare le quattro funzioni…
Explaining Change Paths of Systems and Software Development Practices
2010
This chapter discusses how systems development practices are shaped. Based on interviews conducted in ten development organizations and previous literature, we identify eight types of change paths in systems development practices: emergence, adoption, idealization, formalization, abandonment, informalization, entropy, and disobedience. We argue that the eight change path types provide an integrated theoretical framework on the study of how systems development practices change in organizations, projects, and among individual developers in a given context. We discuss how this framework complements existing theories and concepts of the contemporary literature on systems development.
