“…The results of Muthukumaran and Baskaran (2013) were 635 mg/L of TSS (Table 2), which also produces fresh, eviscerated seafood, but the products processed are squid and scallops. In the fish-preservation industry, concentrations of this parameter may be higher, such as those found in effluent from the sardine-canning industry, which presented concentrations ranging from 120 to 4,980 mg/L of TSS (Achour et al, 2000). For the tuna effluent, the concentration found was up to 6,100 mg/L (Achour et al, 2000).…”

Potential for reuse of effluent from fish-processing industries

The most common problems in the fish processing industry relate to high water consumption and the generation of effluents with concentrated organic loads. Given that reuse can represent an alternative for sustainable development, this study sought to assess the potential for recycling effluents produced in a fish-processing plant. In order to do so, the final industrial effluent was analyzed using the American Public Health Association (APHA) standard effluent-analysis method (2005). In addition, the study assessed treatments which produce effluents meeting the requirements prescribed by different countries' regulations for reuse and recycling. The results found that effluents with smaller organic loads, such as those from health barriers and monoblock washing, can be treated in order to remove nutrients and solids so that they can be subsequently reused. For effluents produced by the washing and gutting cylinders, it is recommended that large fragments of solid waste be removed beforehand. Effluents can in this way attain a quality compatible with industrial reuse. This study further highlights the possibility of treating effluents so as comply with drinking water standards. This would potentially allow them to be used within the actual fish-processing procedure; in such a case, a revision of standards and measures for controlling use should be considered to prevent microbiological damage to products and risks to handlers and final consumers.Keywords: effluent treatment, fish processing, reuse, sustainability. Potencial de reuso de efluente de indústrias de processamento de pescado RESUMOOs problemas mais comuns em indústrias processadoras de pescado estão relacionados ao alto consumo de água e à geração de efluente contendo cargas orgânicas concentradas. Sendo o reuso uma alternativa para o desenvolvimento sustentável na indústria, este estudo teve como objetivo avaliar o potencial de reciclo de efluentes gerados em uma indústria processadora de pescado. Para isto, realizou-se a caracterização do efluente industrial final empregando métodos padrões para a análise de esgoto da American Public Health Association, APHA (2005). Em adição, foram avaliados tratamentos empregados capazes de produzir efluentes que atendem 731 Potential for reuse of effluent of fish-processing industries Rev. Ambient. Água vol. 12 n. 5 Taubaté -Sep. / Oct. 2017 aos requisitos preconizados por regulamentos de diferentes países para o reuso e reciclo. Os resultados obtidos demonstraram que os efluentes com menores cargas orgânicas, como os da barreira sanitária e lavagem de monoblocos, podem ser submetidos a tratamentos que priorizem a remoção de nutrientes e sólidos para posterior reciclo. Para o efluente proveniente de etapas do cilindro de lavagem e da evisceração, recomenda-se previamente a remoção dos resíduos sólidos grosseiros, de maneira que o efluente quando submetido a tratamento possa alcançar qualidade para o reuso industrial. Destaca-se ainda a possibilidade de tratar esses efluentes de modo que atendam as caracterís...

“…Lipids, typically the tri-glyceride esters of long chain fatty acids (LCFAs), represent an important fraction of the organic matter in dairy wastewater [1][2][3], fish waste [4,5], ice-cream wastes [6], oil/ fat wastewater [7], slaughterhouse wastewater [8][9][10] and vegetable waste [11] from food processing industries. The lipids are neither easily decomposed biologically, nor by other conventional means due to their floating on the surface of the wastewater [7].…”

“…Ching and Ghufran (2017) reported 2.2% total solids (consisting up to 550 mg% TSS and 260 mg% dissolved solids), 50 mg% each of ammonia and nitrate nitrogen, and up to 100 mg% of phosphate typical effluent. Tuna processing effluents contained TSS, fat, chemical oxygen demand (COD), and biochemical oxygen demand (BOD) at 1,570, 450, 11,100, and 6,600 mg per lg, respectively (Achour et al, 2000). These losses deprive the consumers of significant amounts of nutrients.…”

Valorization of Seafood Processing Discards: Bioconversion and Bio-Refinery Approaches

The seafood industry generates large volumes of waste. These include processing discards consisting of shell, head, bones intestine, fin, skin, voluminous amounts of wastewater discharged as effluents, and low-value under-utilized fish, which are caught as by-catch of commercial fishing operations. The discards, effluents, and by-catch are rich in nutrients including proteins, amino acids, lipids containing good proportions of polyunsaturated fatty acids (PUFA), carotenoids, and minerals. The seafood waste is, therefore, responsible for loss of nutrients and serious environmental hazards. It is important that the waste is subjected to secondary processing and valorization to address the problems. Although chemical processes are available for waste treatment, most of these processes have inherent weaknesses. Biological treatments, however, are environmentally friendly, safe, and cost-effective. Biological treatments are based on bioconversion processes, which help with the recovery of valuable ingredients from by-catch, processing discards, and effluents, without losing their inherent bioactivities. Major bioconversion processes make use of microbial fermentations or actions of exogenously added enzymes on the waste components. Recent developments in algal biotechnology offer novel processes for biotransformation of nutrients as single cell proteins, which can be used as feedstock for the recovery of valuable ingredients and also biofuel. Bioconversion options in conjunction with a bio-refinery approach have potential for eco-friendly and economical management of seafood waste that can support sustainable seafood production.
