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.
Opportunities, Challenges, and Solutions in Expanding The Blue Economy in Sri Lanka: Special Reference to The Fisheries Sector
Researchers analyzed the opportunities, challenges, and solutions for expanding the blue economy in Sri Lanka with a focus on the fisheries sector. The study emphasizes the importance of sustainable marine resource utilization while addressing environmental threats including plastic pollution that affect ocean ecosystem health.
Implementation of SDG 14 and Blue Economy Policies in Southeast Asia: A Comparative Policy Review
This policy review examines how seven Southeast Asian nations are implementing the UN's ocean sustainability goal (SDG 14) and blue economy frameworks, covering issues like marine protected areas, fishing practices, and waste management. While plastic waste and marine litter enter the discussion in the context of ocean health, the paper is primarily a comparative policy analysis rather than a microplastics research study. It is tangentially relevant as a governance backdrop for reducing plastic pollution at sea.
Microplastics Content of Seaweeds in the Mariculture Potential Zone at The Southwest of Coastal Bawean Island
Researchers investigated microplastic contamination in seaweeds from Bawean Island, Indonesia, finding that even sheltered coastal waters contained microplastics in red, green, and brown seaweed species collected from mariculture potential zones.
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.
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.
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.
Industri Bioplastik Starch-Cellulose Blend Tandan Kosong Kelapa Sawit dalam Pemenuhan Sustainable Development Goals
This industrial design study proposes converting oil palm waste from Indonesia into starch-cellulose bioplastic as an alternative to conventional plastics, which degrade into ocean microplastics. The proposed 16,500-ton-per-year plant would transform agricultural residue into a biodegradable material, potentially reducing the volume of persistent plastic entering marine environments while supporting sustainable development goals.
Role of microalgae as a sustainable alternative of biopolymers and its application in industries
Not a microplastics paper — this review examines the potential of algae-derived biopolymers (such as alginate, carrageenan, and polyhydroxyalkanoates) as biodegradable, eco-friendly replacements for petroleum-based plastics, highlighting their advantages but noting challenges for large-scale production.
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.
Successful Blue Economy Examples With an Emphasis on International Perspectives
This study examines successful international examples of Blue Economy development - sustainable ocean-based economic activities - drawing lessons for policy and practice from marine aquaculture, renewable energy, and ocean tourism initiatives. The examples illustrate how well-governed ocean industries can deliver economic benefits while protecting the marine environment from pollution threats including microplastics.
Algal bioplastics: current market trends and technical aspects
Researchers reviewed the status and commercial potential of algal bioplastics as a sustainable alternative to fossil-based plastics, finding that microalgae outperform plants and microbes for bioplastic feedstock due to their fast growth and wastewater remediation capacity, while cost remains a key barrier to scale-up.
