Eco-Friendly Bioplastic Material Development Via Sustainable Seaweed Biocomposite
AI summary Read the abstract
Researchers developed a seaweed-based bioplastic film using Gracilaria edulis algae combined with starch, glycerol, and chitosan. The resulting material showed mechanical properties comparable to starch-based commercial plastics, good biodegradability, and compostability, and showed potential for use in low-moisture food packaging. This work contributes to the effort to replace petroleum-based plastics with renewable alternatives that break down in the environment rather than persisting as microplastic pollution.
Abstract The study focused on the development of an environmentally friendly bioplastic material using sustainable seaweed-based biocomposites. Algal biomass ( Gracilaria edulis ) was processed and combined with starch, glycerol, glacial acetic acid, and chitosan to create flexible, homogenous biopolymer films. These films exhibited comparable physical properties to commercial plastics and retained their inherent colour post-processing. Spectroscopic analysis revealed intense UV-Vis peak points aligned with seaweed composition. Mechanical testing demonstrated adequate strength and flexibility, similar to starch-based bioplastics, with a tensile strength of 3.383 MPa and lower elongation strength of about 31.90 %. Material migration tests indicated a preference for water, suggesting suitability for low-moisture foods. The bioplastic film displayed notable biodegradability and compostability, showcasing its potential as a sustainable alternative for food packaging. This innovative contribution advances eco-friendly bioplastic material, addressing plastic pollution and promoting biocomposite use.

Researchers developed a bioplastic composite from alginate and carrageenan — both derived from seaweed — and tested how varying carrageenan content affected its physical and mechanical properties. Higher carrageenan content improved strength and flexibility. Seaweed-based bioplastics could replace conventional plastics in packaging applications while reducing plastic pollution.
Eco-Friendly Biopolymers Shaping Sustainable Food Packaging
AI summary Read the abstract
This review examines seaweed-derived biopolymers—particularly alginates and carrageenans—as materials for sustainable food packaging, covering their properties, processing methods, and performance as barriers to moisture and gases. It evaluates their potential to replace petroleum-based plastics and their degradation profiles under real-world conditions.
Seaweed Biopolymers in Packaging
AI summary Read the abstract
This review rounds up existing research on using seaweed to make food packaging and edible films instead of plastic, since seaweed-based materials can naturally break down and even help keep food fresh longer by blocking oxygen and germs. Swapping out conventional plastic for seaweed alternatives could mean less plastic waste and fewer microplastics ending up in our food and water — though the technology is still being refined for wider commercial use.
An Overview of the Alternative Use of Seaweeds to Produce Safe and Sustainable Bio-Packaging
AI summary Read the abstract
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.
Bio-Inspired Eco-Composite Materials Seaweed Waste Integration for Sustainable Structural Applications
AI summary Read the abstract
Researchers developed biodegradable substrates incorporating seaweed residue for cultivating algae in marine environments, aiming to address both plastic pollution and carbon dioxide emissions. Adding algae powder accelerated degradation in seawater, with up to 12% mass loss after two months of immersion. The study suggests these bio-inspired composites could serve dual purposes: supporting marine algae growth while gradually breaking down instead of persisting as plastic waste.
