Environmental impacts of olive oil production: an LCA case study in the Province of Messina (Sicily)
2010
Investigating on the environmental sustainability of organic animal products? The case of organic eggs
2020
Abstract The organic farming of laying hens is experiencing a growing trend in Italy, following an increase in consumer demand for organic eggs. The present study aimed to investigate the environmental performance of organic egg production for the first time in the Italian context. To this end, the Life Cycle Assessment (LCA) of organic egg production in a farm rearing laying hens located in Northern Italy was performed. The analysis was carried out in a cradle to farm gate perspective, with 1 kg of eggs selected as functional unit. Primary data relating to animal performances and resources consumed was collected on site, and subsequently integrated with secondary data, including estimates …
ELISA: A simplified tool for evaluating the Environmental Life-cycle Impacts of Solar Air-conditioning systems
2018
The paper presents ELISA, a simplified tool for estimating the Environmental Life-cycle Impacts of Solar Air-conditioning systems. The tool is designed to support researchers, designers and decision makers in a simplified evaluation of the life cycle energy and environmental potential benefits related to the installation of solar heating and cooling systems in substitution of conventional ones. The tool was developed within the research activities of Task 53 “New Generation Solar Cooling & Heating Systems (PV or solar thermally driven systems)” of the International Energy Agency.
Life Cycle Assessment di sistemi per le auto elettriche
2011
Il documento descrive la valutazione delle prestazioni energetico – ambientali di batterie Li- Ione adatte all'alimentazione della propulsione elettrica pura, comprensive del sistema BMS (Battery Management System), realizzata tramite l’applicazione della metodologia dell’Analisi del Ciclo di Vita (Life Cycle Assessment – LCA), in accordo alle norme della serie ISO 14040 ed all’International Reference Life Cycle Data System (ILCD) Handbook. L’attività è iniziata con un’analisi dettagliata dello stato dell’arte internazionale sulla LCA applicata alle batterie al Li-Ione, che ha definito il contesto scientifico di riferimento della valutazione energetico-ambientale condotta. E’ stata poi svil…
Life Cycle Assessment of Flow-Redox Cells: A Case Study
2022
European Union identified the battery value chain as strategic for achieving a sustainable and decarbonized economy. Focusing on the environmental sustainability of batteries, this paper presents an application of the Life Cycle Assessment methodology to three flow-redox cells characterized by electrodes made by different materials. The results are referred to one kWh of energy supplied by the cell during its useful life and are calculated following a “from cradle to grave” approach. Negligible differences (lower than 1.5%) are observed in the energy and environmental impacts of the three types of cells, mainly due to the type of electrode and the use phase. A dominance analysis shows that …
Comparative LCA of renovation of buildings towards the nearly Zero Energy Building
2018
The building sector is one of the key sectors to achieve the 20/20/20 targets of the EU as there is the potential to lead to significant energy savings reducing the EU’s total energy consumption by 5-6% and lowering CO2 emissions by 5%. One powerful mechanism to apply principle and criteria of nearly zero-energy buildings (nZEB). This work, done in the framework of the agreement between the Italian Ministry of Economic development and ENEA on the “Research of electric system” (Ricerca di Sistema Elettrico), has the aim to evaluate the environmental impacts of the technological improvements needed for enhancing the performances of an average building to a nZEB (or at least in the direction o…
Life Cycle Assessment of organic apple supply chain in the North of Italy.
2015
The goal of the study is the assessment of the energy and environmental impacts of 1 ton of organic apples cultivated in the North of Italy, by applying the Life Cycle Assessment methodology. The authors examined the supply chain of apples, by including the supply of raw materials and energy sources, and the farming step. In addition, an assessment of apple distribution to the final users was made. The results show that a relevant share of the total impacts is caused by the transport to the final users, assuming that the product is distributed on local, national and international markets. A detailed analysis of the farming step shows that a significant share in the overall energy and enviro…
Environmental assessment of a waste-to-energy practice: The pyrolysis of agro-industrial biomass residues
2021
Abstract The bio-wastes pyrolysis is a waste to energy strategy that converts bio-wastes into valuable products (bio-char, bio-oil) with wide use in the agri-food sector. However, limited efforts are paid to the investigation of its environmental sustainability: in this context, the study contributes the need towards the assessment of a wide range of environmental impacts for the pyrolysis process of different types of bio-wastes under different operating conditions. The study estimates the potential environmental impacts related to bio-char production from the pyrolysis of several different agro-industrial residues and different temperatures and identifies the process “hot spots”. The anal…
Uncertainty analysis of life cycle assessment of asphalt surfacings
2023
The Life Cycle Assessment (LCA) of asphalt pavements are associated with significant uncertainty resulting from variability in the quantity and impact of individual components, the quality of data for each component, and variability of asphalt durability. This study presents a framework to quantify and incorporate the uncertainty of LCA and asphalt durability data into LCA of asphalt surfacings. The suggested framework includes: estimating the uncertainty of asphalt production processes by the pedigree matrix method, conducting a deterministic LCA, applying Monte Carlo Simulation (MCS) to estimate the probability density functions (PDFs) of the considered impacts using the uncertainty data,…
