“…The generated wastewater by food processing units, which is normally from non-process functions, mostly contains high levels of organic contaminants such as chemical oxygen demand (COD), biological oxygen demand (BOD), high nutrients (nitrogen and phosphorus), and different chemicals like solvents and ions (Saxena et al, 2020;Shahid et al, 2020). These wastewaters also contain noticeable amounts of raw materials or products in the form of organic loads, nutrients, and suspended solids, which can be separated and recovered during the treatment process (Udugama et al, 2020). Novel approaches of water consumption management in the framework of circular economy can facilitate resource recovery and provide higher productivity and sustainability in food production (Narasimmalu & Ramasamy, 2020).…”

Food processing is among the greatest water-consuming industries with a significant role in the implementation of sustainable development goals. Waterconsuming industries such as food processing have become a threat to limited freshwater resources, and numerous attempts are being carried out in order to develop and apply novel approaches for water management in these industries. Studies have shown the positive impact of the new methods of process integration (e.g., water pinch, mathematical optimization, etc.) in maximizing water reuse and recycle. Applying these methods in food processing industries not only significantly supported water consumption minimization but also contributed to environmental protection by reducing wastewater generation. The methods can also increase the productivity of these industries and direct them to sustainable production. This interconnection led to a new subcategory in nexus studies known as water-food-environment nexus. The nexus assures sustainable food production with minimum freshwater consumption and minimizes the environmental destructions caused by untreated wastewater discharge. The aim of this study was to provide a thorough review of water-food-environment nexus application in food processing industries and explore the nexus from different aspects.The current study explored the process of food industries in different sectors regarding water consumption and wastewater generation, both qualitatively and quantitatively. The most recent wastewater treatment methods carried out in different food processing sectors were also reviewed. This review provided a comprehensive literature for choosing the optimum scenario of water and wastewater management in food processing industries.

“…However, considering the brain drain concept in a panoramic and non-specific way. Such panoramic perspective understands brain drain as a social phenomenon mainly related to sustainable technological development, a sustainability type that has recently been studied within the SDGs framework [121][122][123][124][125][126][127][128][129][130].…”

Scholars had been documenting the Brain Drain phenomenon producing scientific literature for more than 50 years. After three decades of slow but steady progress, literature about this concept has accelerated its progress and growth path, in line with the 9th sustainable development goal “Build resilient infrastructure, promote sustainable industrialization and foster innovation” Thus, the present article aims to define the current theoretical trends about the analysis of advanced intellectual human capital’s international migratory phenomenon. This study uses a scientometric methodology on a corpus of 1212 articles indexed to the JCR-WoS from Social Sciences. The period covered in the study is from 1965 to 2020. The paper looks to understand how researchers studied the brain drain concept over the last 55 years in various disciplines. The report covers 99 categories from the Journal Citation Report (JCR) index. Results show that there is a scientific research critical mass that is studying the brain drain phenomenon. The analysis shows thematic trends at the sources, discourses, and consolidates classic works and some novel authors. Those new scholars and theoretical trends lead to refocused analysis beyond countries with a high development level. Such movement constitutes a new challenge in this line of research toward studying the effects of the brain drain in the peripheral areas of knowledge production.

“…At least, Udugama et al . (2019, p. 143) emphasise the need to address potential logistical challenges, knowing well that ‘in many resource recovery solutions this can be somewhat complex as the required feedstock (waste stream) is distributed and only available in smaller quantities’. By contrast, we found that the logistics question mainly depends on transportation costs in relation to the (expected) added value of by‐products.…”

“…At this point, we bring into play 'nexus thinking' as a lens for analysing cross-sectoral integration to improve overall resource efficiency (Hoff 2011). However, only few studies on food waste valorisation explicitly adopt this perspective so far, with recent exceptions elaborating on management alternatives (Kibler et al 2018) and commercialisation prospects of technological solutions (Udugama et al 2019).…”

The treatment of organic waste, by‐products and other residual materials from bio‐based industries is currently changing from disposing to recycling and reusing activities, which may create significant added values. However, these valorisation pathways as well as their institutional and geographical contexts are not yet sufficiently understood. From an actor‐centric perspective, we seek to shed light on extant practices of agri‐food waste valorisation using the examples of potato and rapeseed production in Lower Saxony, Germany. Drawing on conceptual thoughts on circular bioeconomies and the nexus approach, we will show that these practices not only depend on the availability of (technological) solutions but are affected by changing economic and political environments in combination with place‐specific conditions and local networks. We further describe the cross‐sectoral relations, synergies and externalities that come along with by‐product valorisation in multi‐use systems, while also revealing the fragile stability of circular bioeconomies that are linked to the food–feed–energy nexus.
