Towards the implementation of circular economy in the water softening industry: A technical, economic and environmental analysis
2020
Abstract To reduce the environmental impact of the industrial sectors, circular strategies should be implemented to purify the effluents and recover raw materials. In this context, a novel integrated methodological approach is proposed to identify the most suitable strategy to improve the sustainability of the water softening industry via the treatment and recycling of the produced wastewater. Different concentration technologies and energy supply systems are compared to find economically feasible and environmentally friendly treatment systems. The investigated chains present the same pre-treatment step (nanofiltration and crystallization) and different concentration technologies: Multi-Eff…
Techno-economic assessment of multi-effect distillation process for the treatment and recycling of ion exchange resin spent brines
2019
Abstract A treatment chain including nanofiltration, crystallization and multi-effect distillation (MED) is for the first time proposed for the treatment of an effluent produced during the regeneration of Ion Exchange resins employed for water softening. The goal is to recover the minerals and to restore the regenerant solution to be reused in the next regeneration cycle. MED is the most crucial unit of the treatment chain from an economic point of view. A techno-economic analysis on the MED unit was performed and a novel performance indicator, named Levelized Brine Cost, was introduced as a measure of the economic feasibility of the process. Different scenarios were analysed, assuming diff…
Electrodialysis Applications in Wastewater Treatment for Environmental Protection and Resources Recovery: A Systematic Review on Progress and Perspec…
2020
This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and othe…
L’analisi delle simbolizzazioni affettive delle Aree Naturali Protette per un turismo responsabile. Il caso studio delle Riserva Naturale Orientata d…
2013
ABSTRACT This paper presents a research on responsible tourism in protected areas, through the case study of Zingaro Nature Reserve (Sicily). The main objectives of this study were to examine the so-called collusive processes elaborated by different stakeholder of natural protected area and to propose strategies and guidelines for intervention in the perspective of sustainable development and responsible use of the local tourist activities, based on the results. The methodology applied was Emotional Analysis of the Text (EAT) that allowed to investigate the emotional representations and the expectations of stakeholders, through the study of co-occurrances of the so-called dense words, using…
Ethical and responsible tourism: a tool for promoting values and social justice. Two case studies of Sicily, Italy
2019
In recent decades an ethical and responsible tourism has become increasingly important in the context of a general orientation to promote sustainable development models in the world. The recognition of the negative impacts of mass tourism has led to a profound reflection on tourism and its contribution to the development of a territory. The debate has highlighted the importance of promoting a sustainable and responsible tourism development that brings economic, social and environmental benefits to the local community and its members. The importance of promoting an ethic of tourism for the progress of society has been equally emphasized. Values must not be forgotten in leisure time as they c…
L’investissement conforme à la Charia est-il socialement responsable ?
2019
Cette étude propose une réflexion inédite sur la pertinence d’inclure l’ICC dans la sphère de l’ISR. Nous établissons une comparaison à la fois qualitative et quantitative entre ces deux types d’investissement pour comprendre dans quelle mesure l’ICC se distingue de l’ISR. Les résultats révèlent une surperformance financière de l’ICC en période de crise en dépit d’une sous-performance sociétale. Nous concluons que, bien que l’ICC obéisse à une certaine conception de l’ISR, la non-inclusion des considérations ESG dans ses règles de management actuelles devrait conduire les communautés académique et professionnelle à le traiter en tant que type d’investissement à part entière.
E-corporate social responsibility in socially responsible firms: the case of Spanish firms
2011
The design and the content of a website that is positively valued by the firm's stakeholders can become a source of competitive advantage. In recent years, information on the extent to which the firm undertakes its social responsibility and environmental protection efforts is gaining increasing interest among the agents with whom it interacts. The aim of this paper is to analyse e-corporate social responsibility in firms listed in the socially responsible investment index FTSE4Good Ibex, focusing on the type of information concerning the corporate social responsibility, which this type of firms provides via their websites.
BIOCHARS IN SOILS: TOWARDS THE REQUIRED LEVEL OF SCIENTIFIC UNDERSTANDING
2017
The special issue on Biochar as an Option for Sustainable Resource Management Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were addressed: soil biodiversity and ecotoxicology, soil organic matter and greenhouse gas (GHG) emissions, soil physical properties, nutrient cycles and crop production, and soil remediation. The highest future research priorities regarding biochar’s effects in soils were: functional …
VERSO UN’ARCHITETTURA RESPONSABILE ED ADATTIVA
2022
L’intento è quello di analizzare le affinità e differenze che contribuiscono il passaggio concettuale per gestire la complessità del progetto tecnologico attraverso le sue realizzazioni di nuova concezione, che ad oggi dovranno esser ripensate nel loro atto realizzativo con le conseguenti ricadute responsabili verso l’ambiente ed il territorio. A tal proposito è risultato utile introdurre la “Direttiva Europea 85/384” con i suoi undici punti che delinea la figura dell’architetto. Il progettista dovrà esser una figura consapevole di un sapere trasversale fondato su ‘conoscenze’ e ‘capacità’ ormai dedite al risparmio delle risorse e lontano dalla velleità da palcoscenico. The intent is to ana…
CLUSTER OF COUNTRIES ANALYSIS BY RESPONSIBLE COMPETITIVENESS, NATIONAL COMPETITIVENESS AND CORRUPTION
2008
The Global Competitiveness Report, the State of Responsible Competitiveness and the Global Corruption Barometer elaborate annually a countries ranking that emphasize the progress or regress of each country. Using this reports the paper try to make a clusters analysis of world country by responsible competitiveness, national competitiveness and corruption. The main idea of this paper is to split the countries in three categories of clusters - innovators, asserters and beginners - in relation between responsible competitiveness and national competitiveness - and - stars, asserters and beginners - in relation between corruption and national competitiveness. Within the three clusters, countries…
