Integration of green roofs&walls in urban areas
2020
Growing urbanization is associated with the emergence of environmental problems, such as the reduction of natural resources, the atmosphere pollution and the increase of the heat islands phenomenon in cities. The integration of vegetation in the urban areas, through the creation of green hanging systems, represents a possible solution to improve the energy sustainability of buildings, to combat meteoric excesses, to improve stormwater management and to reduce pollutant levels. These energy and environmental benefits are related to the properties of evapotranspiration, shading and thermal insulation of the vegetation. The work reports the results of the main studies concerning the use of han…
Environmental Sustainability Orientation, Reward-Based Crowdfunding, and Venture Capital: The Mediating Role of Crowdfunding Performance for New Tech…
2021
Extant literature has investigated the effects of new ventures’ environmental sustainability orientation (ESO) on the crowdfunding (CF) performance and on the ability to secure venture capital, separately and with mixed results. In this article, we address the study of these relationships simultaneously. Specifically, we examine how the presence of ESO features influences new technology-based ventures’ ability to secure funding in reward-based CF campaigns and how the CF performance mediates the effect of such features on attracting subsequent venture capital. Using a sample of new hardware ventures that have launched a CF campaign on Kickstarter, we document a negative effect of the presen…
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…
An intertemporal approach to measuring environmental performance with directional distance functions: Greenhouse gas emissions in the European Union
2014
Abstract The impact of economic activity on the environment is a matter of growing concern for firm managers, policymakers, researchers and society as a whole. Building on previous work by Kortelainen (2008) [Dynamic environmental performance analysis: A Malmquist index approach. Ecological Economics 64, 701–715], we contribute an approach to assessing intertemporal environmental performance at the level of the management of specific pollutants, as the result of change in eco-efficiency and environmental technical change, which identify catching-up with best available environmental practices and eco-innovation, respectively. In doing so, we use Data Envelopment Analysis techniques, directio…
Microbiological characteristics of compost produced from dairy and wine by-products
2019
Wine and dairy chains rapresent of the agri-foof leading sectors in Sicily. Composting residues from these two chains would contribute to increase the environmental sustainability of the production with additional advantages represented by the reduction the costs recover soil fertility. This work represents the first attempt to combine the green of the vine cultivation as well as wine and dairy by-products. Raw materials provided potential bioactivators identified as Bacillus subtilis, Bacillus velezensis and Kocuria rhizophila which showed cellulolytic activity. The strain were inocultated in the mass to be composted in order to accelerate the process. Four compost trials were performed: (…
Business Sustainable Competitiveness a Synergistic, Long-Run Approach of a Company's Resources and Results
2018
Abstract Business sustainable competitiveness is a very complex concept. This complexity generates a variety of possibilities to define, to measure and to test it. The purpose of the paper is to develop the concept of businessness (for business sustainable competitiveness) by leveraging productivity, profitability, effectiveness and sustainability, at firm level. The interrelations between them, in terms of revenues per employee, return on assets, total assets turnover and Dow Jones Sustainability Index, were integrated into models/functions in order to develop, test and apply businessness. The article is about proposing functions (by using multiple discriminant analysis) in order to measur…
Assessing Urban Environmental Sustainability by Means of Indicators: The Case of the Heritage Buildings
2002
Man in developed countries is looking for new and more suitable paradigms of a correct evolution, founded on an improved level of quality of life, on a pollution-free environment and on the availability of rising amount of time to be spent in pleasure and cultural activities.
The Landfilling of Municipal Solid Waste and the Sustainability of the Related Transportation Activities
2022
The management of municipal solid waste is a crucial issue to address as we move toward the decarbonization of urban contexts. Not by chance, this sector plays a relevant role in the Covenant of Mayors program, whereby municipalities are called to design their own Sustainable Energy Action Plans (SECAPs). However, despite new regulations strongly pushing the recycling and reuse of materials contained in municipal waste, many cities still use large landfills. As part of the overall environmental pressure exerted by these urban systems, the transport of waste from collection points to landfills or treatment facilities must be considered in order to correctly assess the full environmental burd…
Dynamic Sustainability. Sustainability Window Analysis of Chinese Poverty-Environment Nexus Development
2015
Sustainability Window is a new analysis tool for assessing the sustainability of development simultaneously in all of its three dimensions (environmental, economic, and social). The analysis method provides information of the maximum and minimum economic development that is required to maintain the direction of social and environmental development towards more sustainable targets. With the Sustainability Window method it is possible to easily analyze the sustainability using different indicators and different time periods making comparative analyses easy. The new method makes it also possible to analyze the dynamics of the sustainability and the changes over time in the width of the window.…
Nomenclature for Hydrogeological Instability Risks
2022
The nomenclature for hydrogeological instability risks includes four main risks, which are distinguished according to the risk causes : 1) hydrogeological risk, that is slowly caused by natural factors (e.g. collapse landslides in a calcareous cliff in uninhabited areas and erosion along a marly-calcareous slope) in environments where human activities are minimal, i.e. woods, forests and mountain pastures; 2) hydraulic-pedological farming risk, that implies the occurrence of landslides in every winter and is caused by incorrect crop selection, not suitable for the soil and climate parameters (e.g. on a hilly slope with a clay vertisol type with a landslide having different fronts, when the …
