The industrial mussel processing generates significant quantities of waste. Nearly 30% of one metric tonne of processed mussel is finally destined for human consumption. Regardless of the mussel commodities, an important quantity of waste is concentrated at several sub-processes, such as input reception, washing and declumping shells, and mussel meat extraction stages, or by means of the rejection of mussels only due to a size characteristic criterion established by the target market. Despite the main segregated waste comprising shells, byssus threads, residual meat and wastewater, a heterogeneous composition must be taken into account, since much of the solid waste is commonly gathered and compacted for landfill transportation purposes. This paper reviews the sustainable management strategies for mussel by-products, addressing their limitations for an industrial implementation to obtain value-added products. It is concluded that, although there is a well-known diversity of waste sustainable management alternatives, several proposed products (e.g., collagen, bio-adhesives, biopolymer, and adsorbent for pollutants) still remain in a potential framework, circumscribed into laboratory results, subject to an optimization process, to a validation by industrial pre-scale trials, or even limited by the associated production costs. Future researches should focus on reducing the uncertainties linked with their technical–economic feasibility for an industrial scale development.

工业贻贝加工会产生大量废物。一公吨加工贻贝中近 30% 最终用于人类消费。无论贻贝商品如何，大量废物都集中在几个子过程中，例如输入接收、清洗和去壳以及贻贝肉提取阶段，或者仅根据尺寸特征标准拒绝贻贝由目标市场确定。尽管主要的分离废物包括贝壳、肉丝、残留的肉和废水，但必须考虑异质成分，因为大部分固体废物通常被收集和压实用于填埋运输目的。本文回顾了贻贝副产品的可持续管理策略，解决它们在工业实施以获得增值产品方面的局限性。得出的结论是，尽管众所周知的废物可持续管理替代方案的多样性，但一些提议的产品（例如，胶原蛋白、生物粘合剂、生物聚合物和污染物吸附剂）仍处于潜在框架中，仅限于实验室结果，受制于优化过程，通过工业规模试验进行验证，甚至受到相关生产成本的限制。未来的研究应侧重于减少与其工业规模发展的技术经济可行性相关的不确定性。几种提议的产品（例如，胶原蛋白、生物粘合剂、生物聚合物和污染物吸附剂）仍处于潜在框架中，受限于实验室结果，经过优化过程，通过工业规模试验验证，甚至受限由相关的生产成本。未来的研究应侧重于减少与其工业规模发展的技术经济可行性相关的不确定性。几种提议的产品（例如，胶原蛋白、生物粘合剂、生物聚合物和污染物吸附剂）仍处于潜在框架中，受限于实验室结果，经过优化过程，通过工业规模试验验证，甚至受限由相关的生产成本。未来的研究应侧重于减少与其工业规模发展的技术经济可行性相关的不确定性。
