Grounds and Challenges for Implementing a Circular Economy in the European Road Transport Sector

2017

Environmental challenges, especially in the form of resource depletion, pollution and greenhouse gas emission, are very important challenges for the socio-economic development. For this reason, the concept of a circular economy has been developed and is being implemented in different areas. In 2015, the European Union adopted the Circular Economy Package consisting of an “EU Action Plan for the Circular Economy”, presenting a set of actions aimed at achieving objectives of the circular economy in Europe. The goal of the paper is to describe and discuss key challenges facing implementation of the concept of the circular economy in the European road transport sector. First, the concept of a c…

Toward a European Eco-label brand for residential buildings: Holistic or by-components approaches?

2011

The Eco-label scheme is becoming ever more important in the environmental certification of products and services, especially in light of the recent ambitious aim of containing greenhouse emissions and improving the efficiency of utilizing energy sources. A recently-introduced hypothesis concerns the European Eco-label scheme relating to buildings, in the awareness that the construction industry is of primary importance to the whole economic and social life of states. This scheme should adopt an integrated approach to environmental problems and include construction, day-to-day management, and the possible disposal of building materials, throughout the life cycle of the building. In addition,…

Measuring the eco-efficiency of wastewater treatment plants under data uncertainty

2018

Abstract Eco-efficiency assessment is a useful tool for improving the sustainability of wastewater treatment plants (WWTPs). However, it is a complex task that requires the integration of several performance indicators into a single index. Data envelopment analysis (DEA) is established as a highly effective methodology for achieving this as it permits the integration of the service value, resource consumption and environmental impact variables as the desirable outputs, inputs and undesirable outputs, respectively. However, traditional DEA models omit uncertainties in the data that are likely to result in biased conclusions. This study pioneers the assessment of the eco-efficiency of WWTPs w…

Phenology and Fruit Growth Dynamics of Mango (Mangifera indica L.) in Greenhouse and Open Air in Mediterranean Climate

2023

AbstractPhenological evolution of shoots and fruit growth of three mango varieties—Keitt, Osteen and Tommy Atkins—were monitored during two reproductive seasons, from full flowering to fruit harvest on trees cultivated in the open air and inside a greenhouse, in the island of Sicily—Italy. The aim of the study was to assess the behavior of mango trees subjected to summer high temperatures under a permanent plastic cover in the Mediterranean climate. Differences between open air and greenhouse emerged in the dates of first record of major phenological stages and in their duration, and in the fruit growth rates. Greenhouse cultivated trees showed a significant anticipation of flowering and ri…

SOIL FERTILITY, GREENHOUSE GAS EMISSIONS AND AGRONOMIC PERFORMANCE IN A VINEYARD WITH DIFFERENT SOIL MANAGEMENT IN A SEMIARID MEDITERRANEAN ENVIRONME…

2017

In the semiarid Mediterranean environment, vineyard soils are often characterised by intensive tillage and large supply of inorganic fertilizers. Those practices, coupled with the semiarid Mediterranean climate features (warm to hot, dry summers and mild, wet winters),speed up the mineralisation of soil organic matter (SOM) so that many lands have lost much fertility. To counteract SOM decline, the introduction of cover crops with or without nitrogen (N) fixing forage legumes, has become a management technique widely used. Indeed, cover crops besides increasing SOM and potentially mineralisable N, it can mitigate soil erosion in sloping vineyards. However, the competition risk for soil wate…

Greenhouse Gas Emissions from Membrane Bioreactors

2017

Nowadays, it is widely accepted that wastewater treatment plants (WWTPs) are significant sources of greenhouse gas (GHG) emission, contributing to the anthropogenic sources. Among the GHG emitted from WWTPs, nitrous oxide (N2O) has been identified of having the major interest/concern, since its high global warming potential (GWP), is 298 times higher than that of CO2 and also to its capability to react with stratospheric ozone causing the layer depletion. Up to now, most of the experimental investigations have been carried out on conventional activated sludge (CAS) processes. The knowledge of N2O emission from advanced technologies such membrane bioreactors (MBRs) is still very limited. The…

Quantifying sensitivity and uncertainty analysis of a new mathematical model for the evaluation of greenhouse gas emissions from membrane bioreactors

2015

Abstract A new mathematical model able to quantify greenhouse gas (GHG) emissions in terms of carbon dioxide (CO 2 ) and nitrous oxide (N 2 O) for a Membrane Bioreactor (MBR) is presented. The proposed mathematical model is of the Activated Sludge Model (ASM) family and takes into account simultaneously both biological and physical processes (e.g., membrane fouling). An analysis of the key factors and sources of uncertainty influencing GHG emissions is also presented. Specifically, the standardized regression coefficient, the Extended-FAST and a Monte Carlo based method are employed for assessing model factors which influence three performance indicators: effluent quality index, operational…
