“…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).…”

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. K E Y W O R D Scircular economy, food processing, nexus, wastewater treatment, water management INTRODUCTIONIncreased global demand for freshwater due to population growth has put the water resources under stress for the recent decades. Water scarcity is predicted to get more intensive in the forthcoming years (Piesse, 2020). Statistical data demonstrated that annual water consumption in three main different sectors of agriculture, industries, and

The town of Pastos Chicos (Jujuy-Argentina), presents arsenic (As) concentrations in soil (49 mgAs kg−1) and water (1.44 mgAs L−1) significantly above the maximum allowable limits set by National Laws No 24,585 and N° 24,051. This study aimed to evaluate the effect of llama manure (Lama glama) and Trichoderma strain T1R3 on As uptake and toxicity in Swiss chard (Beta vulgaris var. cicla) and broad bean (Vicia faba L.) crops, while assessing potential human health risks. Results indicated that Trichoderma strain T1R3 inoculation stimulated broad bean plant growth by reducing As stress. Swiss chard crops treated with 5% manure and a manure/Trichoderma T1R3 combination reduced As absorption from 32.46 to 64.02% in roots, and from 35.2 to 44.5% in leaves. Broad bean crops inoculated with Trichoderma T1R3 showed a significant mitigation of toxicant accumulation in the leaves (67.42%). Also, the manure/Trichoderma T1R3 combination reduced As accumulation (57.46%) in broad bean roots. The efficacy of llama manure and of the llama manure/Trichoderma T1R3 combination in reducing health hazards that derive from As intake by consuming chard leaves was also reflected in Hazard Quotient < 1 values. Although Cancer Risk values decreased considerably, these showed there was a considerable carcinogenic risk for humans consuming chard leaves. These observations reveal that adding llama manure and Trichoderma T1R3 might mitigate As uptake by crops, thus reducing human health risks. This study advanced our understanding the complex llama manure/Trichoderma strain interactions in As-contaminated soils, which are imperative for developing the effective mitigations strategies.

“…The pH of the soil plays an important role in the As bioavailability, and its subsequent bioaccumulation in plants (Nawab et al 2018). In the present study, the alkaline pH of the soil and water (Table 2) could have contributed to As coprecipitation with sulfate or calcium, reducing its availability (Natasha et al 2020). According to Chaoua et al (2019), in alkaline pH soils, the concentrations of metal ions drop due to an increased surface oxide charge, or on account of either process of precipitation of metal hydroxides, or formation of insoluble organic complexes.…”
