ClearHarnessing seaweed farming for climate mitigation in South Korea: evaluating carbon dioxide removal potential and future research directions
Researchers evaluated the potential of seaweed farming as a carbon dioxide removal strategy in South Korea. They found that seaweed cultivation can sequester carbon through biomass storage and dissolved organic carbon release, while also substituting carbon-intensive products. The study suggests that scaling up seaweed aquaculture could contribute meaningfully to climate mitigation goals, though more research is needed on long-term carbon storage pathways.
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.
Recent Advances in Seaweed Biorefineries and Assessment of Their Potential for Carbon Capture and Storage
Not relevant to microplastics research; this paper reviews the potential of seaweed-based coastal marine biorefineries for producing third-generation biofuels and capturing atmospheric carbon dioxide.
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.
A comparative environmental life cycle assessment of hatchery, cultivation, and preservation of the kelpSaccharina latissima
Researchers conducted a comparative environmental life cycle assessment of hatchery, cultivation, and preservation stages for the brown seaweed Saccharina latissima at a pilot facility in Sweden, accounting for nutrient bioremediation and carbon capture benefits. The study evaluated the environmental sustainability profile of seaweed cultivation as part of potential contributions to the circular bioeconomy.
Recent Advances in Seaweed Biorefineries and Assessment of Their Potential for Carbon Capture and Storage
This review covers recent advances in seaweed biorefinery technologies for producing biofuels, high-value chemicals, and carbon capture, examining the technical challenges that limit large-scale production. Seaweeds are highlighted for their rapid growth, lack of competition with food crops, and potential for CO2 sequestration.
Harnessing green tide Ulva biomass for carbon dioxide sequestration
Researchers reviewed the potential of using Ulva seaweed from harmful green tide blooms as a resource for carbon dioxide sequestration through biochar production. They estimated that Ulva biomass could capture approximately 3.85 million tons of CO2 equivalent, with nearly half stabilized through conversion to biochar. While not directly about microplastics, the study explores how repurposing marine biomass could address both coastal pollution and climate change.
Development of a framework and toolbox for measuring and evaluating ecosystem interactions of seaweed aquaculture
This Dutch-language study (mostly in Dutch) developed a framework and toolbox for measuring ecosystem integrity in seaweed cultivation areas off the Dutch coast, relevant to scaling up sustainable aquaculture. Healthy coastal ecosystems with minimal microplastic contamination are important for sustainable seaweed production.
Novel seaweed-based bioplastic: A prospective Life Cycle Assessment
This PhD thesis uses life cycle assessment (LCA) to evaluate the environmental impacts of making bioplastic from brown seaweed. Seaweed-based bioplastics could offer a lower-impact alternative to conventional plastics, potentially reducing the generation of persistent microplastics in the environment.
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.
Bio-Inspired Eco-Composite Materials Seaweed Waste Integration for Sustainable Structural Applications
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.
Enhanced Microplastic Burial in China’s Coastal Blue Carbon Ecosystems: Drivers and Potential Roles in Climate Change Mitigation
Researchers measured microplastic stocks in coastal blue carbon ecosystems along the Chinese coastline and found that these environments significantly enhance the trapping and burial of microplastic particles in sediments. Microplastic-derived carbon storage ranged from 0.01 to 104.4 kg of carbon per hectare across the study sites. The study suggests that while blue carbon ecosystems act as sinks for microplastic pollution, this buried plastic carbon may need to be accounted for in coastal carbon budget assessments.
Seaweed as a sink for microplastic contamination: Uptake, identifications and food safety implications
This review examines how seaweed, a widely consumed food, absorbs and accumulates microplastics from ocean water. Research shows seaweed can account for up to 45.5% of total dietary microplastic intake in some regions, with particularly high levels in South Asia. The findings are concerning for human health because seaweed is eaten directly and is also increasingly used in health supplements and food additives.

Ecosystem Services Provided by Seaweeds
This review summarizes the many ecosystem services that seaweeds provide, including food production, carbon storage, water filtration, and habitat for marine life. Seaweeds can also help combat pollution by absorbing heavy metals and other contaminants from the water. The review is relevant to microplastics research because healthy seaweed ecosystems may play a role in filtering microplastics from ocean water, and damage to these ecosystems could worsen marine plastic pollution.

Spatio-temporal features of microplastics pollution in macroalgae growing in an important mariculture area, China
Researchers investigated microplastic contamination in cultivated macroalgae from Haizhou Bay, a major mariculture area in China. They found that seaweed harvested during the culture period contained higher microplastic levels than during non-culture periods, with fibers making up over 90% of particles. The study suggests that aquaculture gear is a significant source of microplastic pollution, releasing an estimated 1,037 tons of plastic into the environment annually.
The seaweed Chaetomorpha linum cultivated in an integrated multitrophic aquaculture system: A new tool for microplastic bioremediation?
Researchers tested whether the seaweed Chaetomorpha linum, grown in an aquaculture system, could trap microplastics from surrounding water. The seaweed effectively captured microplastic particles in its tangled filaments, and a simple washing procedure could remove most of the trapped plastics from the harvested biomass. This suggests that growing certain seaweeds could serve as a natural, low-cost way to filter microplastics from marine environments.
