Valorization of marine-derived wastes as green sorbents

This article reviews various synthesis and modification methods employed for valorization of marine-derived wastes into green sorbents, which show promise for mitigating pollutants from diverse sources. This approach is particularly relevant for promoting sustainable development in shellfish processing industry. In-depth discussions cover the physicochemical characteristics of the green sorbents, including surface area and porosity, sorption capacity and surface functionality, and how they affect their reactivity with different pollutants. The prospects and technical challenges associated with regenerating these green sorbents are highlighted and addressed to conclude this state-of-the-art review.
