A Comparison of Solar and Conventional Pavements Via Life Cycle Assessment
2023
The sustainable and green development of roads is lately receiving significant attention. As a multi-functional road capable of both accommodating traffic loads and generating clean energy, solar pavements exhibit a strategic opportunity for the future path of development in the road engineering. Although solar pavements have significant environmental benefits during their operation, they can lead to increased carbon emissions during the process of material preparation, construction, maintenance, etc. Therefore, it is essential to implement the framework of Life Cycle Assessment (LCA) to investigate their potential environmental impacts and/or benefits. Hence, this paper systematically anal…
Life Cycle Assessment of olive oil: a case study in Southern Italy
2018
The paper describes the results of a specific LCA based analysis of the production of oil in the region of Calabria, in southern Italy. The goal of the study is to assess the energy and environmental impacts of different scenarios involving conventional and organic cultivations, plains and hills cultivations and involving different operating techniques. The study also aims at assessing the share of each life cycle step on the total of energy and environmental impacts. The functional unit chosen for the comparative analysis is a glass bottle of 0.75 l of extra-vergine oil. A “from cradle to gate” perspective was chosen. The analysis was developed according to the LCA standards of the ISO 140…
Life Cycle Assessment of solar heating and cooling systems: the tool “ELISA”
2018
Solar heating and cooling (SHC) systems play an important role in the achievement of energy and climate European goals. The benefits of these technologies should be evaluated taking into account their lifecycle energy and environmental impacts, calculated by applying the Life Cycle Assessment (LCA) methodology. The development of a complete LCA can be difficult and time-consuming particularly for no-LCA experts, discouraging them in the inclusion of the lifecycle perspective in their assessments. To overcome this limit, the paper presents “ELISA - Environmental Lifecycle Impacts of Solar Air-conditioning systems”, a user-friendly simplified tool for estimating the lifecycle energy and envir…
A new sustainable food delivery platform
2022
In recent years, the food delivery business has expanded with great success and during the last months, pandemic have contributed to the growth of online food delivery. Consequently, with this fast growth of the online food delivery commerce, it’s important to analyze its environmental effects. In fact, the downside is represented by the enormous volume of waste produced by this market, consisting of packaging mostly made with materials such as paper, cardboard, plastic, and aluminum; a problem which, in relation to the volume of orders and the limits of separate collection that is not always efficient, leads to a quantity of unmanaged waste. This study aims to assess the impact of urban fo…
Artificial Neural Networks to assess energy and environmental performance of buildings: An Italian case study
2019
Abstract Approximately 40% of the European energy consumption and a large proportion of environmental impacts are related to the building sector. However, the selection of adequate and correct designs can provide considerable energy savings and reduce environmental impacts. To achieve this objective, a simultaneous energy and environmental assessment of a building's life cycle is necessary. To date, the resolution of this complex problem is entrusted to numerous software and calculation algorithms that are often complex to use. They involve long diagnosis phases and are characterised by the lack of a common language. Despite the efforts by the scientific community in the building sector, th…
Energy and Environmental Life Cycle Assessment of asphalt pavements: A Scenario Analysis for Urban Roads
2018
This paper aims at calculating the life-cycle energy and the environmental impacts pertaining to roads management, including materials production, transportation, construction, maintenance, and rehabilitation. A life-cycle approach is applied to assess energy and environmental impacts of a typical Italian urban road, according to the ISO 14040 series. In more detail, the Authors assess the energy and environmental profile of different optimized scenarios of bituminous mixtures. The aim of scenario analysis is to identify the less impacting scenario from an energy and environmental point of view. For each analysed scenario, the contribution of each life-cycle step to the total impacts and th…
The energy and environmental impacts of Italian households consumptions: An input–output approach
2011
Abstract Promoting sustainable consumption and production patterns is a key challenge for the future, in order to use the Earth resources efficiently, to reduce the greenhouse gas emissions, and to decouple the economic growth from the environmental degradation. New or customized methods have to be applied to support decisions makers in the choice of environmental-friendly products, and to select policy priorities and sustainable strategies. A modified input–output model can aid to analyse the relationships among economic growth, energy consumptions and pollutants, in order to assess the energy and environmental impacts due to the actual production and consumption patterns. The following pa…
Energy and environmental impacts of Energy related products (ErP): a case study of biomass-fuelled systems
2014
Abstract Energy-related Products (ErP) account for a large proportion of European energy and natural resource consumption. In 2007, ErP were responsible for the consumption of about 239 Mtoe of electricity and about 555 Mtoe of fuels. In order to reduce the energy and environmental impacts of these products, the European Commission published the Directive 2009/125/EC on the eco-design of ErP. This Directive represents a key component of European policy for improving the energy and environmental performances of products in the internal market. In this context, it is important to develop scientific research aimed at assessing the energy and environmental impacts of ErP, and at defining their …
From biomass waste to tri-generation: a life-cycle experience in the “agro-combined” of Thibar
2018
The paper presents a Life Cycle Assessment of the energy tri-generation from biomass waste in a plant located in Tunisia. The analysis included the plant construction and end-of-life, the supply of biomass, its use for biogas production and the electricity, heating and cooling generation from biogas. The study is one of the first applications of environmental analysis to tri-generation from biomass waste in developing countries. The results showed that the plant construction is responsible of 76% of primary energy consumption and gives a contribution higher than 88% on resource depletion and ionising radiation. The operation causes 66% of the impact on human toxicity - cancer effects and mo…
LCA of an Asphalt Mixture Produced in a Southern Italian Plant: Analysis and Perspectives
2021
In recent years, a growing attention on environmental issues affecting all fields and procedures of the productive sectors has raised, aiming to reduce energy and raw-material consumptions and pollution effects on environment. Due to the involved volumes and to the nature of the related materials and productive processes, the civil and road sectors have been strongly invested by this change of perspective. Therefore, a proper estimation of the environmental impacts for the entire life cycle of the asphalt mixtures for road construction and maintenance activities is extremely important. For performing similar investigations, Life Cycle Assessment (LCA) has become one of the most reliable and…
