Bio inspired marine system for microplastics

Microplastic pollution has emerged as a major threat to marine ecosystems, fisheries, and sustainable blue economy development. This study presents a conceptual bio-inspired marine system designed to capture microplastics and potentially convert plastic-derived compounds into usable energy. Inspired by efficient fish locomotion, the proposed system integrates passive filtration, biomimetic propulsion, and emerging bioenergy technologies to support autonomous marine cleanup operations.

The study reviews the chemical stability of common microplastics, including polyethylene and polypropylene, and highlights the limitations of natural biological degradation. Since aquatic organisms cannot directly metabolize plastics, the research explores indirect conversion pathways such as microbial degradation, microbial fuel cells, and catalytic oxidation processes. These mechanisms may enable partial recovery of energy from plastic waste while reducing environmental accumulation.

The proposed design emphasizes ecological safety by favoring synthetic or hybrid bio-inspired systems over genetically modified organisms. Such systems could minimize risks to marine biodiversity while improving controllability and operational efficiency. The concept also aligns with global blue economy goals by promoting cleaner oceans, sustainable fisheries, and innovative marine technologies.

Although the system remains theoretical, this interdisciplinary framework demonstrates the potential of combining biomimicry, environmental engineering, and renewable energy concepts to address marine plastic pollution. Future research should focus on laboratory prototyping, energy-efficiency analysis, and scalable deployment strategies for aquatic environments.
