Fishing nets are a major source of plastic pollution in the oceans, with abandoned nets, known as ghost nets, continuing to entangle and kill marine life for decades. The Great Pacific Garbage Patch, for example, is largely composed of fishing-related plastic waste, with 75-86% of plastic waste identified as coming from offshore fishing activity. The plastic composition of fishing nets includes polyethylene, nylon, polyester, and vinylon. Nylon, in particular, is a common material used in fishing nets due to its strength and low cost, but it does not decompose, contributing to the longevity of ghost nets in the ocean. While recycling fishing nets is challenging due to the special cleaning procedures required, some non-profit organizations are promoting circular approaches to collect and recycle nets into new products. The use of biodegradable plastics in fishing gear has also been proposed as a potential solution to reduce the environmental impact of plastic fishing nets.

Fishing nets are a major source of ocean plastic
A 2018 study published in Scientific Reports found that approximately 46% of the 79 thousand tons of ocean plastic in the Great Pacific Garbage Patch (GPGP) consisted of fishing nets, some as large as football fields. This discovery surprised researchers, who had expected the percentage to be closer to 20%. The Ocean Cleanup's research in 2022 confirmed this, finding that 75% to 86% of all plastic waste in the GPGP originated from offshore fishing activity.
Fishing nets are made of various plastics, including polyethylene, nylon, polyester, and vinylon. These materials are challenging to recycle, and often, recycling companies cannot process them. As a result, end-of-life fishing nets (EOLFNs) are sometimes incinerated or discarded in landfills or the sea. However, recycling fishing nets can reduce environmental impacts and promote a circular economy. For example, the non-profit Enaleia in Greece works with fishers and recycling companies to collect plastics from the sea and transform them into new products like socks, swimming clothes, and furniture.
To address the issue of ghost nets, organizations like Sea Shepherd have launched campaigns such as Operation Ghostnet, using small fast boats and divers to remove hazardous ghost nets and other abandoned fishing gear from coastal areas. Greenpeace has also called for global action and better regulation of the fishing industry to protect marine life from the deadly effects of ghost gear.

Nets are made from polyethylene, nylon, polyester, and more
Fishing nets are a major source of plastic pollution in the oceans, with nets making up a significant portion of the Great Pacific Garbage Patch. Nets are made from a variety of synthetic materials, including polyethylene, nylon, polyester, and vinylon. These materials are chosen for their strength and durability, but this very durability becomes a problem when nets are lost or discarded at sea, where they continue to entangle and kill marine life for decades.
Polyethylene is a common type of plastic, with high-density polyethylene (HDPE) and low-density polyethylene (LDPE) being the most frequently used types in fishing nets. Polyethylene is known for its toughness and flexibility, making it ideal for net manufacture. However, it is non-biodegradable and can persist in the environment for centuries.
Nylon is another key material used in fishing nets. Nylon nets were introduced in the 1960s, replacing traditional rope nets. Nylon is a strong and inexpensive synthetic polymer that is widely used in various applications, including textiles and industrial products. Like polyethylene, nylon does not decompose, making it a significant contributor to the problem of ghost nets.
Polyester is another type of synthetic polymer used in fishing nets. It is known for its durability and resistance to stretching and shrinking, making it suitable for net manufacture. However, like other synthetic net materials, polyester contributes to marine pollution when nets are lost or discarded.
Vinylon is also used in fishing net production, although to a lesser extent than the previously mentioned materials. It is a synthetic fibre with good tensile strength and moisture absorption properties. However, it is non-biodegradable and can persist in the environment if not properly disposed of.
The use of these synthetic materials in fishing nets has led to significant environmental concerns. While recycling is an option for some types of plastic nets, it is not always feasible, and the fishing industry has been criticised for not adequately addressing the problem of ghost nets. There is a growing interest in using biodegradable plastics for fishing gear, which could help reduce the environmental impact of lost or discarded nets.

Nets can be recycled into new products
Fishing nets are a major source of plastic pollution in our oceans. They can be accidentally or purposefully lost, discarded, or abandoned in the sea, where they continue to harm marine life for decades. This has led to the rise of several recycling programs that incentivize the collection of fishing nets and their transformation into new products.
One such program is Net-Works, which focuses on recycling fishing nets into nylon yarn and fibre strings. Local communities are paid to collect and clean the fishing nets, which are then turned into yarn at Aquafil and sold to Interface to make carpet tiles. This program not only removes fishing nets from the ocean but also prevents them from being dumped in the first place, as fishermen can sell their old nets directly to Net-Works.
Another program, Net Positiva, was created by Bureo to establish environmentally sound disposal points for fishermen, from which they can source material for their products. Bureo creates a range of products from recycled fishing nets, including mugs, performance fabrics, and hat brims. Their signature material, NetPlus, is made from 100% post-consumer recycled fishing nets and can be turned into high-quality yarns.
POPSICASE is another company that uses recycled fishing nets in its products. Their phone cases are made from fishing nets recovered from the Mediterranean Sea and are Revivack Certified, meaning they can be returned to the brand to be totally recovered, leaving no waste behind. ECOALF is another sustainable fashion brand that uses recycled nylon from fishing nets in its products, such as its Wild Sherpa Backpack.
Recycling fishing nets not only helps to create new products but also provides an effective way to reduce waste and promote a circular economy.

Nets can be repurposed or reused
Fishing nets are a major source of plastic pollution in our oceans, with approximately 46% of the 79 thousand tons of ocean plastic in the Great Pacific Garbage Patch being made up of nets. These nets, also known as "ghost nets", continue to kill marine life for decades after being lost or discarded at sea.
However, there are several ways in which fishing nets can be repurposed or reused to prevent them from becoming marine debris. Nets that are still in relatively good condition can be donated to local community organisations, schools, or arts centres for use in educational exhibitions, decorative elements, jewellery, or other creative projects. Larger nets can be reused as garden trellises or support for climbing plants.
Recycling companies are also working to collect and recycle fishing nets into new, sustainable products. For example, the non-profit enterprise Enaleia in Greece works with fishers and recycling companies to promote a circular approach to marine plastic waste. Enaleia hires coordinators at ports to collect and weigh plastic recovered by fishing boats, which is then taken to recycling companies and transformed into pellets or flakes. These can then be used as raw materials for manufacturing new items such as plastic lumber, carpets, clothing, accessories, or other plastic products. Another example is the Net-Works program, which focuses on recycling discarded fishing nets into nylon yarn or strings of fibre. Local communities collect and clean the fishing nets in return for money, and the nets are then turned into yarn and sold to companies like Interface to make carpet tiles.
In addition to removing ghost nets from the ocean, some organisations are also working proactively to prevent nets from being dumped at sea in the first place. For instance, Fishermen can now sell their old nets directly to Net-Works, and Nofir works with fishing companies to collect and recycle nets before they enter the ocean.

Biodegradable fishing gear could reduce plastic waste
Fishing nets are made from synthetic organic polymers, usually referred to as plastics. The most common type of plastic used in fishing nets is polyethylene, which makes up 27.4% of the plastic content, followed by nylon at 33.6%, polyester at 17.6%, and vinylon at 11.7%.
Fishing nets are a significant source of ocean plastic pollution, with approximately 46% of the 79 thousand tons of ocean plastic in the Great Pacific Garbage Patch consisting of lost, abandoned, or discarded fishing nets, also known as "ghost nets." These nets can continue to entangle and kill marine life for decades, contributing to a decline in fish populations and the entanglement of marine animals.
To address this issue, there have been efforts to promote the recycling of fishing nets and the development of biodegradable fishing gear. Recycling fishing nets can reduce waste and promote a circular economy, but it is important to note that not all types of plastic can be recycled, and special cleaning procedures may be required.
Biodegradable fishing gear, such as nets made from biodegradable plastics, has the potential to reduce plastic pollution significantly. For example, the Innovative Fishing Gear for Oceans (INdIGO) project aims to develop the first completely biodegradable net with a controlled lifespan. The net is designed to break down organically into natural materials within two years, rather than persisting as microplastics for centuries.
While biodegradable fishing gear shows promise in reducing plastic waste, it is not a cure-all solution. Some fishers reject biodegradable nets because they are more expensive, break more easily, and can be lost more easily than traditional nets. However, biodegradable nets are just as effective at catching fish as standard nylon nets, and their acceptance among fishers is gradually improving. Additionally, new plastics are being developed that are as stable as nylon but break down when exposed to UV radiation for extended periods.

Frequently asked questions
Fishing nets are made from plastic, specifically nylon, which is a material that is much stronger and cheaper than rope.
Plastic fishing nets have a detrimental impact on the environment, particularly marine life. When nets are lost or discarded at sea, they continue to trap and kill marine animals for decades. This has led to a decline in some fish populations and the entanglement of marine mammals such as dolphins and sea lions.
There are several approaches to mitigate the issue of plastic fishing nets in our oceans. Some organizations, such as Sea Shepherd, focus on removing ghost nets through campaigns and divers. Additionally, recycling initiatives like Enaleia work with fishers and recycling companies to collect and recycle plastic fishing gear. Another potential solution is the use of biodegradable plastics for fishing gear, which could break down naturally over time.
Ghost nets refer to lost, abandoned, or discarded fishing nets that continue to entangle and kill marine life. They are considered "ghost nets" because they operate like ghosts, continuing to catch fish and other sea creatures long after they have been lost or discarded.
