ClearAn Overview of the Alternative Use of Seaweeds to Produce Safe and Sustainable Bio-Packaging
This review explores how compounds derived from seaweed, particularly polysaccharides like alginates and carrageenans, can be used to create biodegradable packaging as an alternative to conventional plastics. Researchers found that seaweed-based biopolymers offer both functional packaging properties and potential health benefits, while avoiding the microplastic pollution caused by petroleum-based plastics. The approach represents a promising step toward reducing ocean plastic contamination by replacing single-use plastics with marine-sourced biodegradable materials.
