Among the seafood used globally, shellfish consumption is in great demand. The utilization of these shellfish such as prawn/shrimp has opened a new market for the utilization of the shellfish wastes. Considering the trends on the production of wealth from wastes, shrimp shell wastes seem an important resource for the generation of high value products when processed on the principles of a biorefinery. In recent years, various chemical strategies have been tried to valorize the shrimp shell wastes, which required harsh chemicals such as HCl and NaOH for demineralization (DM) and deproteination (DP) of the shrimp wastes. Disposal of chemicals by the chitin and chitosan industries into the aquatic bodies pose harm to the aquatic flora and fauna. Thus, there has been intensive efforts to develop safe and sustainable technologies for the management of shrimp shell wastes. This review provides an insight about environmentally-friendly methods along with biological methods to valorize the shrimp waste compared to the strategies employing concentrated chemicals. The main objective of this review article is to explain the utilization shrimp shell wastes in a productive manner such that it would be offer environment and economic sustainability. The application of valorized by-products developed from the shrimp shell wastes and physical methods to improve the pretreatment process of shellfish wastes for valorization are also highlighted in this paper.

在全球使用的海产品中，对贝类的消费有很大的需求。对虾，虾等贝类的利用为贝类废弃物的利用开拓了新的市场。考虑到利用废料生产财富的趋势，虾壳废料似乎是根据生物精炼厂的原理进行生产的高价值产品的重要资源。近年来，尝试了各种化学方法来对虾壳废物进行增值，这需要苛刻的化学药品（例如HCl和NaOH）来对虾废物进行脱矿质（DM）和去蛋白（DP）。几丁质和壳聚糖工业向水体中处置化学药品会对水生动植物造成危害。从而，人们一直在努力开发安全，可持续的技术来管理虾壳废物。与采用浓缩化学品的策略相比，本综述提供了有关环保方法以及生物方法对虾废物进行增值的见解。这篇评论文章的主要目的是以生产方式解释虾壳废物的利用，从而为环境和经济可持续性提供条件。本文还着重介绍了利用虾壳废料开发的增值副产物和物理方法在改善贝类废料的预处理过程中的增值作用。与采用浓缩化学品的策略相比，本综述提供了有关环保方法以及生物方法对虾废物进行增值的见解。这篇评论文章的主要目的是以生产方式解释虾壳废物的利用，从而为环境和经济可持续性提供条件。本文还着重介绍了利用虾壳废料开发的增值副产物和物理方法在改善贝类废料的预处理过程中的增值作用。与采用浓缩化学品的策略相比，本综述提供了有关环保方法以及生物方法对虾废物进行增值的见解。这篇评论文章的主要目的是以生产方式解释虾壳废物的利用，从而为环境和经济可持续性提供条件。本文还着重介绍了利用虾壳废料开发的增值副产物和物理方法在改善贝类废料的预处理过程中的增值作用。
