Recycling Approach of Marine Plastic Litter: Highly Filled Composites Obtained by Loading Waste Fishing Nets Fiber into Fluidified Recycled Polystyrene and Acrylonitrile Butadiene Styrene
AI summary Read the abstract
This study explores recycling waste fishing nets by embedding their fibers into recycled polystyrene and ABS plastics to create highly filled composite materials. The approach offers a pathway to reduce marine plastic litter from abandoned fishing gear while producing useful recycled material.
Plastic and microplastic pollution in the marine environment is a global issue and lost or discarded fishing nets represent a part of the marine litter. The lost or abandoned fishing gear, like fishing nets, is very harmful to marine organisms due to microplastics release and ghost fishing. Finding recovery and recycling strategies (mechanical, chemical or thermal) for marine plastic waste is a challenge and an opportunity to contribute to the reduction of plastic waste within the framework of a circular economy.

Mechanical Recycling of Post-Consumer Polypropylene Fishing Nets: Effect of Blending with Virgin Polymer
AI summary Read the abstract
Scientists took old, discarded fishing nets, a major source of ocean plastic pollution, and turned them into new plastic material by blending them with fresh plastic. The recycled blend performed well enough to be reused in products, which could mean less plastic waste polluting oceans, breaking down into microplastics, and eventually ending up in our food and water.
Challenges and Opportunities for Recycled Polyethylene Fishing Nets: Towards a Circular Economy
AI summary Read the abstract
Researchers examined the challenges of recycling polyethylene from discarded fishing nets, finding that contaminants and degradation during the nets' service life significantly reduce the mechanical properties of recycled resins. The study explores strategies to improve recycled fishing net polyethylene quality and advance circular economy approaches for marine plastic waste.
The mitigation of the ghost nets threat by recycling of polypropylene: Blends, their ageing tests and spectral characterization
AI summary Read the abstract
Researchers developed a method to recycle polypropylene plastic from abandoned fishing nets — a major source of ocean microplastics — by blending recycled fibers with fresh plastic and testing the resulting material in simulated seawater. The recycled blends held up as well as new plastic, suggesting ghost net recycling is a practical strategy to reduce marine microplastic pollution.
Fishing net waste management: quantification and valorization
AI summary Read the abstract
Abandoned and discarded fishing nets are a major source of microplastics in the ocean because they are made of synthetic fibers that slowly fragment over time. This study quantified the volume of fishing net waste generated in a Portuguese fishing port and evaluated strategies for diverting it from landfill toward recycling and material recovery. Effective management of fishing gear waste is a practical lever for reducing one of the most persistent sources of marine microplastic pollution.
Mitigation approach of plastic and microplastic pollution through recycling of fishing nets at the end of life
AI summary Read the abstract
Discarded fishing nets are a major source of ocean plastic pollution, harming marine life and breaking down into microplastics that can enter the food chain and, eventually, our bodies. Scientists found a way to turn these old nets into new durable materials by combining them with other recycled plastics, offering a practical way to keep this waste out of the ocean and landfills. This kind of recycling could help shrink the growing microplastic problem at its source, rather than just cleaning up after it happens.
