Water Reuse in the Food Industry: Quality of Original Wastewater Before Treatments

2017

This chapter introduces one of the most important emergencies in the world of food and non-food industries: the availability of clean and drinking water. Water use has more than tripled globally since 1950: water quality and its scarcity are increasingly recognised as one of the most important environmental threats to humankind. In addition, the food and beverage processing industry requires copious amounts of water. For these reasons, direct and indirect water reuse systems are becoming more and more interesting and promising technologies. Different reuse guidelines have been recently issued as the result of risk assessment and management approaches linked to health-based targets. Chemical…

Sperata resilienza

2018

Il termine ‘resilienza’ proveniva dalla metallurgia: indica, nella tecnologia metallurgica, la capacità di un metallo di resistere alle forze che vi vengono applicate. Per un metallo, la resilienza rappresenta il contrario della fragilità. Così anche in campo psicologico: la persona resiliente è l’opposto di una facilmente vulnerabile, ovvero che vive: la Notte dell’io (Mormese C., 2004). Etimologicamente ‘resilienza’ viene fatta deriva dal latino resalio, iterativo di salio. Qualcuno propone un collegamento suggestivo fra il signiicato originario di resalio, che connotava anche il gesto dell’uomo di risalire sull’imbarcazione capovolta dalla forza del mare, e l’attuale utilizzo in campo ps…

A study on graph representations for genetic programming

2020

Graph representations promise several desirable properties for Genetic Programming (GP); multiple-output programs, natural representations of code reuse and, in many cases, an innate mechanism for neutral drift. Each graph GP technique provides a program representation, genetic operators and overarching evolutionary algorithm. This makes it difficult to identify the individual causes of empirical differences, both between these methods and in comparison to traditional GP. In this work, we empirically study the behavior of Cartesian Genetic Programming (CGP), Linear Genetic Programming (LGP), Evolving Graphs by Graph Programming (EGGP) and traditional GP. By fixing some aspects of the config…

Research focusing on plant performance in constructed wetlands and agronomic application of treated wastewater – A set of experimental studies in Sic…

2019

Constructed wetlands are sustainable technologies for the treatment of wastewater. These biological systems have been widely studied throughout the world for more than 30 years; however, most studies have focused on the effects of design and engineering on pollutant removal from wastewater. Undoubtedly, agro-technical aspects have been given too little consideration by research. This paper reports the main results of a set of experiments carried out on two pilot horizontal subsurface flow systems in Sicily (Italy). Festuca, Lolium and Pennisetum spp. in combination and three emergent macrophytes-Arundo donax L., Cyperus alternifolius L. and Typha latifolia L.-alone, were assessed. The aim o…

Balancing food waste and sustainability goals in online food delivery: Towards a comprehensive conceptual framework

2022

Increasing food waste is a major threat to sustainability and food security. Recognizing the issue, the United Nations Sustainable Development Goal (SDG) 12 mandates reducing global food waste by 50 percent by 2030. This situation has also given impetus to academic research on consumer food waste in both household and out-of-home settings. However, food delivery apps (FDAs) remain under-researched from this perspective. This is a serious gap because operating under a business model that inherently facilitates food over-ordering, FDAs can be a major source of food waste. Understanding the demand-side factors that drive consumers to order more food than required to satiate their hunger can be…

Re-build landscape. Design for the reuse of abandoned quarries

2021

Looking at the history of our geological and mining heritage, we can see the evolution of the role played by underground mining sites over the centuries. However, if the activity of quarrying stones is as old as the presence of humans on earth, the issue of the territorial regeneration, based on the recovery and re-functionalization of abandoned quarries, is one of the central arguments of the contemporary debate. The extractive activity that on one hand constitutes an important economic resource for numerous territories, on the other hand requires particular attention to the environmental impact it causes. The theme is that of the so-called drosscapes, soils and residual spaces, once margi…

Pienamente conservare per pienamente fruire: il paradigma della Vucciria di Palermo nel Progetto I-Access

2021

Già dal nome la città di Palermo rivela una delle sue peculiarità più significative, ovvero la capacità di accogliere: dal greco «Pan ormos» - tutto porto. In generale, consapevole della vocazione di Palermo, il mercato della Vucciria è stato scelto per illustrare i contenuti del Progetto Interreg Italia-Malta, I-Access di Implementare l'accessibilità alla fruizione e alla conoscenza del centro storico urbano e per le somiglianze e le differenze riscontrate nel La Valletta e Palermo. Il progetto I-ACCESS ha verificato un metodo per promuovere l'accessibilità in senso culturale e fisico e questa esperienza può essere ripetuta in altri centri storici. La conoscenza della realtà materiale del …

The state of water resources in major mediterranean islands

2014

This work analyses the state of water resources in six Mediterranean islands: Corsica, Crete, Cyprus, Mallorca, Malta and Sicily. The analysis is focused on the prevailing social, economic and hydroclimatological characteristics of these islands in order to identify the main common features affecting water availability, demand and use. A detailed analysis of the state of water resources in all the considered islands has been carried out. A background of current conditions relating to freshwater availability, quality and use has been established. Different strategies to face water scarcity and enhance water quality in theislands have been assessed in a context of climate change which is a co…

Zeolites for the nutrient recovery from wastewater

2023

To meet the growing food demand of the world population, excessive use of chemical fertilizers is occurring to improve soil fertility and crop production. The excessive use of chemical fertilizers is not economically and environmentally sustainable. Indeed, from one hand, due to the increasing demand of fertilizers is rising their costs whereas, on the other hand, the accumulation of fertilizers in wastewaters is altering the homeostasis of the ecosystems thus causing serious damages to human health [1,2]. The recovery of nutrients, such as nitrogen (N) and phosphorus (P), from wastewaters is a good option to counteract both economic and environmental issues raised by the excessive use of f…
