ClearPredicting the Composition and Mechanical Properties of Seaweed Bioplastics from the Scientific Literature: A Machine Learning Approach for Modeling Sparse Data
This paper is not relevant to microplastics research — it applies machine learning to predict the mechanical properties of seaweed-based bioplastic films, focusing on biodegradable material design rather than microplastic pollution or its health effects.
Food packaging based on biodegradable polymers from seaweeds: a systematic review
This systematic review examines the use of seaweed-based biodegradable polymers as alternatives to conventional plastic food packaging. The research explores how seaweed materials can provide effective food packaging while breaking down naturally in the environment. Replacing petroleum-based plastics with biodegradable alternatives is one strategy for reducing the microplastic pollution that enters our food and water.
The environmental impact and economic feasibility assessment of composite calcium alginate bioplastics derived from Sargassum
Researchers assessed the environmental impact and economic feasibility of producing calcium alginate bioplastics from Sargassum seaweed, presenting a novel approach that could address both plastic pollution and invasive seaweed problems in the Caribbean.
Emerging technologies for conversion of sustainable macroalgal carrageenan biomass into L-lactic acid: A state-of-the-art review
This review examines how macroalgae (seaweed) can be converted into lactic acid for making polylactic acid (PLA), a biodegradable plastic alternative. Using non-food biomass like seaweed to produce biodegradable plastics could help reduce dependence on fossil-based plastics that generate persistent microplastic pollution.
Contribution of seaweed farming to the mitigation of greenhouse gas emissions and microplastics pollution
Researchers reviewed how seaweed farming can help fight two major environmental problems: seaweed absorbs CO2 from the atmosphere without competing for agricultural land, and seaweed-derived polymers can be used to make biodegradable plastics that break down without generating persistent microplastics. Scaling up seaweed-based bioplastics remains limited by production costs, but the potential environmental benefits make further research worthwhile.
Eco-Friendly Bioplastic Material Development Via Sustainable Seaweed Biocomposite
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.
Food safety in the seaweed food supply chain : Inventory of production, consumption and chemical and physical hazards
This Dutch food safety report inventories the chemical and physical hazards — including microplastics — present in seaweed cultivated for human consumption. As the seaweed food market grows, understanding contamination risks including plastic particles is important for protecting consumer health.
An 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.
Processing and Characterization of Bioplastics from the Invasive Seaweed Rugulopteryx okamurae
Researchers used the invasive seaweed Rugulopteryx okamurae to develop bioplastic materials by blending it with glycerol and processing by injection molding, finding that higher seaweed content and elevated mold temperature improved the mechanical and functional properties of the resulting bioplastics.
Exploring Seaweed Cultivation in the Marine Environment and Its Interaction with Microplastic
This review examines interactions between seaweed cultivation in marine environments and microplastic pollution, exploring how seaweed can both accumulate microplastics and potentially be used in bioremediation strategies to reduce plastic contamination in coastal waters.
Synthesis and Characterization of Bioplastic from Macroalgae Padina australis
Researchers produced bioplastic from the brown macroalgae Padina australis as an alternative to petroleum-based synthetic plastics, which are major environmental pollutants. The alginate-based bioplastic showed promising material properties, suggesting marine algae could be a sustainable raw material for reducing plastic waste.
A Review of Potency of Cassava Peel Waste and Seaweed Carrageenan as Environmentally Friendly Bioplastic
This Indonesian review examines the potential of cassava peel waste and seaweed carrageenan as raw materials for making biodegradable bioplastics. Replacing conventional plastic packaging with plant-based alternatives could reduce the microplastic particles that accumulate in soil and water from degrading conventional plastics.
Marine Biodegradability and Toxicity of Commercially Available Biobased Plastics -A Sustainable Alternative To Petrochemical Plastics?
This conference abstract examines whether commercially available biobased plastics degrade in the marine environment and whether they produce toxic byproducts. Results suggest that some bioplastics do not biodegrade effectively in seawater and may pose similar risks to marine organisms as conventional petroleum-based plastics.
Microalgae as a Source of Biopolymer - A Comprehensive Review
This review examines microalgae as a source of biopolymers for sustainable plastic alternatives, evaluating the potential of algae-derived materials to address the environmental and health harms caused by conventional plastic waste and microplastic pollution through biodegradable substitutes.

Rehashing Our Insight of Seaweeds as a Potential Source of Foods, Nutraceuticals, and Pharmaceuticals
This review summarizes research on seaweed as a source of beneficial compounds including antioxidants, anti-inflammatory agents, and other health-promoting substances. While not directly about microplastics, the research is relevant because seaweeds grow in marine environments increasingly contaminated with microplastics. Understanding the health benefits of seaweed also requires considering the potential risks of microplastic contamination in these marine food sources.
