Seaweed-based cellulose: Applications, and future perspectives

Area of Science:

• Marine Biotechnology
• Polymer Science
• Biomass Valorization

Background:

• Cellulose, a natural polymer, is traditionally sourced from terrestrial biomass.
• Growing seaweed production presents an opportunity for alternative cellulose extraction.
• Seaweed cellulose research is emerging, with limited comprehensive reviews.

Purpose of the Study:

• To review and synthesize information on seaweed cellulose.
• To explore extraction strategies and applications across green, red, and brown seaweeds.
• To assess the potential of seaweed cellulose for commercial use.

Main Methods:

• Literature review of scientific publications on seaweed cellulose.
• Analysis of cellulose content in various seaweed species.
• Comparison of seaweed cellulose properties with plant-derived cellulose.
• Discussion of extraction techniques and product development.

Main Results:

• Several seaweed species contain significant cellulose content (9-34% dry weight).
• Seaweed cellulose extraction is feasible from phycocolloid waste and specific seaweed types.
• Properties of seaweed cellulose-based products are comparable to plant-based counterparts.
• This review is the first to cover cellulose from all three major seaweed groups.

Conclusions:

• Seaweed cellulose is a viable alternative to terrestrial cellulose.
• Economic extraction methods exist for seaweed-derived cellulose.
• Seaweed cellulose holds significant potential for diverse commercial applications.
