Marine biomass, particularly from waste streams, by-products, underutilized, invasive, or potential cultivable marine species, offers a sustainable source of high-value biopolymers such as collagen and chitin. These macromolecules have gained significant attention due to their biocompatibility, biodegradability, functional versatility, and broad applicability across health, food, wellness, and environmental fields. This review highlights recent advances in the uses of marine-derived collagen and chitin/chitosan. In alignment with the United Nations Sustainable Development Goals (SDGs), we analyze how these applications contribute to sustainability, particularly in SDGs related to responsible consumption and production, good health and well-being, and life below water. Furthermore, we contextualize the advancement of product development using marine collagen and chitin/chitosan within the European Union's Blue bioeconomy strategies, highlighting trends in scientific research and technological innovation through bibliometric and patent data. Finally, the review addresses challenges facing the development of robust value chains for these marine biopolymers, including collaboration, regulatory hurdles, supply-chain constraints, policy and financial support, education and training, and the need for integrated marine resource management. The paper concludes with recommendations for fostering innovation and sustainability in the valorization of these marine resources.
海洋生物质，特别是来自废物流、副产品、未充分利用的、入侵性的或潜在可养殖的海洋物种，提供了诸如胶原蛋白和几丁质等高价值生物聚合物的可持续来源。这些大分子因其生物相容性、生物降解性、功能多样性以及在健康、食品、健康和环境领域的广泛适用性而备受关注。本综述重点介绍了海洋来源胶原蛋白和几丁质/壳聚糖用途的最新进展。与联合国可持续发展目标（SDGs）相一致，我们分析了这些应用如何促进可持续性，特别是在与负责任消费和生产、良好健康与福祉以及水下生物相关的可持续发展目标方面。此外，我们将利用海洋胶原蛋白和几丁质/壳聚糖进行产品开发的进展置于欧盟蓝色生物经济战略背景下，通过文献计量和专利数据突出科学研究和技术创新的趋势。最后，该综述探讨了这些海洋生物聚合物强大价值链发展面临的挑战，包括合作、监管障碍、供应链限制、政策和财政支持、教育与培训以及综合海洋资源管理的必要性。本文最后提出了在这些海洋资源增值过程中促进创新和可持续性的建议。
