The problem of fisheries waste has increased in recent years and has become a global problem influenced by various biological, technical, operational and socioeconomic factors. In this context, the use of these residues as raw materials is a proven approach not only to reduce the crisis of unprecedented magnitude facing the oceans, but also to improve the management of marine resources and increase the competitiveness of the fisheries sector. However, the implementation of valorization strategies at the industrial level is being excessively slow, despite this great potential. Chitosan, a biopolymer extracted from shellfish waste, is a clear example of this because although countless chitosan-based products have been described for a wide variety of applications, commercial products are still limited. To address this drawback, it is essential to consolidate a "bluer" chitosan valorization cycle towards sustainability and circular economy. In this perspective we wanted to focus on the cycle of valorization of chitin, which allows to transform a waste product (chitin) into a material suitable for the development of useful products to solve the source of its origin as a waste product and pollutant; chitosan-based membranes for wastewater remediation.
近年来，渔业废弃物问题日益严重，已成为一个受多种生物、技术、操作和社会经济因素影响的全球性问题。在这种情况下，将这些残留物作为原材料加以利用，不仅可以减少海洋面临的空前规模的危机，而且可以改善海洋资源管理，提高渔业部门的竞争力。然而，尽管具有巨大的潜力，但在工业层面实施增值战略的速度过于缓慢。壳聚糖是一种从贝类废弃物中提取的生物聚合物，就是一个明显的例子，因为尽管已经有无数基于壳聚糖的产品被描述用于各种各样的应用，但商业产品仍然有限。为了解决这一缺点，必须巩固一个更“蓝色”的壳聚糖增值循环，以实现可持续性和循环经济。在这方面，我们希望重点关注甲壳素的增值循环，该循环可以将一种废物（甲壳素）转化为适合开发有用产品的材料，从而解决其作为废物和污染物的来源问题；基于壳聚糖的废水修复膜。
