ClearChallenges and Opportunities for Recycled Polyethylene Fishing Nets: Towards a Circular Economy
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.
Fishing net waste management: quantification and valorization
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.
Developing a Circular Economy for Fishing Gear in the Northern Periphery and Arctic Region: Challenges and Opportunities
This paper examines the challenges and opportunities for creating a circular economy for fishing gear — including lost and abandoned nets — in the Arctic and Northern European region. Discarded fishing gear is a major source of ocean plastic pollution, and recovering and recycling it could significantly reduce marine litter in these remote waters.
Circular Business Models for SMEs in the Fishing Gear Industry
This chapter examines how small and medium enterprises (SMEs) in the fishing gear industry can adopt circular business models to recycle fishing nets, ropes, and components rather than discarding them. Lost and discarded fishing gear is a major source of ocean plastic pollution and microplastic generation in marine environments.
Recycling Approach of Marine Plastic Litter: Highly Filled Composites Obtained by Loading Waste Fishing Nets Fiber into Fluidified Recycled Polystyrene and Acrylonitrile Butadiene Styrene
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.
An Integrated Approach to Assessing the Potential of Plastic Fishing Gear to Release Microplastics
Researchers developed an integrated approach to assess how abandoned, lost, or discarded fishing gear releases microplastics into marine environments. The study found that fishing gear is a significant but understudied source of microplastic pollution, and the research provides new methods for quantifying microplastic release from different types of plastic fishing equipment.
Supplementary file 1_Fishing net waste management: quantification and valorization.docx
Researchers developed a methodology to quantify discarded fishing net waste from Latvia's fishing gear industries and evaluated waste valorisation scenarios including reuse, recycling, and energy recovery using environmental life cycle assessment and environmental damage cost methods. The study frames fishing net waste management within circular economy principles, identifying pathways to reduce microplastic release from abandoned or discarded gear into marine ecosystems.
Source, fate and management of recreational fishing marine debris
Researchers conducted the first global literature review of recreational fishing marine debris, identifying plastic and metal as dominant materials and nearshore reefs and coastal areas as both sources and sinks, while concluding that the sector's contribution to marine debris is likely underestimated and understudied.
Life cycle inventory of plastics losses from seafood supply chains: Methodology and application to French fish products
Researchers developed a life cycle inventory methodology for quantifying plastic losses from seafood supply chains, applying it to French fish products to identify key stages where plastic enters the environment from fishing through retail.
Properties and Recyclability of Abandoned Fishing Net-Based Plastic Debris
This review examines how abandoned, lost, or discarded fishing gear degrades in marine environments through biocatalytic and photocatalytic mechanisms, while exploring the ecological damage caused and evaluating recycling practices and alternative uses as strategies for managing this significant source of marine plastic pollution.
The mitigation of the ghost nets threat by recycling of polypropylene: Blends, their ageing tests and spectral characterization
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.
Life cycle assessment (LCA) on waste management options for derelict fishing gear
Researchers used life cycle assessment to compare four waste management options for derelict fishing gear retrieved from the ocean, including mechanical recycling, syngas production, energy recovery, and landfill disposal. They found that mechanical recycling and energy recovery had the lowest environmental impacts, while syngas production and landfilling were not competitive due to high energy requirements or insufficient offset credits. The study provides guidance for establishing environmentally sound waste management systems for this growing marine litter waste stream.
Designing a Value-Added Tax-integrated recovery scheme for Abandoned, Lost or Discarded Fishing Gear: Science–policy integration and decision-support for Vietnam’s fisheries
Researchers designed a VAT-integrated recovery scheme for abandoned, lost, or discarded fishing gear in Vietnam, finding through a survey of 1,525 fishers that refunding the 5% VAT on new gear in exchange for returning recovered gear at ports — combined with allowing fishers to retain informal resale proceeds — could substantially increase participation in circular economy recovery programs.
Potential microplastic release from beached fishing gear in Great Britain's region of highest fishing litter density
Researchers surveyed abandoned fishing gear on beaches in Great Britain's highest fishing litter density region, characterizing rope and net types to estimate potential microplastic release from degrading marine-based plastic pollution sources.
Quantification and environmental pollution aspects of lost fishing gear in the Nordic countries
Researchers compiled data from Nordic countries on the quantity and composition of abandoned, lost, and discarded fishing gear (ALDFG) in aquatic environments, examining contributions to macro- and microplastic pollution and hazardous chemical contamination, while also evaluating prevention strategies and mitigation options for lost gear impacts.

Recycling Marine Plastic into Clothing Apparel via Global Collaborations
This paper describes initiatives to collect marine plastic waste and convert it into clothing apparel through international collaborations, presenting this as an approach to both cleaning up ocean plastic and creating commercial value. While recycling marine plastic into textiles diverts waste from the ocean, washing synthetic fabrics made from recycled plastic releases microfibers that re-enter water systems. The paper does not address this recycling paradox.
Alternative Rope Materials in Towed Fishing Gear to Reduce Plastic Waste, A Comparative Study of Mechanical Properties and Tolerance Against Wear and Tear
Researchers compared the wear tolerance of 14 different rope materials in demersal fisheries, including conventional synthetic polymers and biodegradable alternatives, to identify lower-plastic options that can reduce fishing gear-derived plastic waste.
An Overview of the Current Trends in Marine Plastic Litter Management for a Sustainable Development
This review summarizes current knowledge about marine plastic litter, from its land-based origins to its distribution across ocean environments, and evaluates recovery and recycling strategies. Researchers found that while technologies for collecting and recycling marine plastics are advancing, significant economic and logistical barriers remain. The study emphasizes that a circular economy approach, combining prevention, collection, and material recovery, is essential for addressing ocean plastic pollution.
