The seafood industry generates waste, including shells, bones, intestines, and wastewater. The discards are nutrient-rich, containing varying concentrations of carotenoids, proteins, chitin, and other minerals. Thus, it is imperative to subject seafood waste, including shrimp waste (SW), to secondary processing and valorization for demineralization and deproteination to retrieve industrially essential compounds. Although several chemical processes are available for SW processing, most of them are inherently ecotoxic. Bioconversion of SW is cost-effective, ecofriendly, and safe. Microbial fermentation and the action of exogenous enzymes are among the significant SW bioconversion processes that transform seafood waste into valuable products. SW is a potential raw material for agrochemicals, microbial culture media, adsorbents, therapeutics, nutraceuticals, and bio-nanomaterials. This review comprehensively elucidates the valorization approaches of SW, addressing the drawbacks of chemically mediated methods for SW treatments. It is a broad overview of the applications associated with nutrient-rich SW, besides highlighting the role of major shrimp-producing countries in exploring SW to achieve safe, ecofriendly, and efficient bio-products.
海鲜产业会产生废物，包括贝壳、骨头、内脏和废水。这些废物富含营养，含有不同浓度的类胡萝卜素、蛋白质、壳聚糖和其他矿物质。因此，必须对海鲜废物进行二次加工和增值处理，进行脱矿质和脱蛋白，以回收工业上必需的化合物。尽管有几种化学工艺可用于处理虾废料（SW），但其中大多数固有地具有生态毒性。SW 的生物转化具有成本效益、环保且安全。微生物发酵和外源酶的作用是 SW 生物转化的重要过程，可将海鲜废物转化为有价值的产品。SW 是农用化学品、微生物培养基、吸附剂、治疗剂、营养保健品和生物纳米材料的潜在原料。本文全面阐述了 SW 的增值方法，解决了 SW 处理中化学介导方法的缺点。除了强调主要的虾生产国在探索 SW 以实现安全、环保和高效的生物产品方面的作用外，本文还广泛概述了与富含营养的 SW 相关的应用。
