Commercial fishing gear represents a significant but often overlooked source of ocean plastic. Nets, ropes, buoys, and other equipment account for roughly 10% of ocean plastic pollution globally, but in some areas—particularly near fishing grounds—they dominate the debris field.

Unlike consumer plastics that break down into microplastics relatively quickly, fishing gear is designed for durability. Heavy-duty ropes and nets can persist in the ocean for decades, continuing to catch and kill marine life long after they’re lost or abandoned. This “ghost fishing” is a major conservation problem.

Australia has developed several programs to address fishing gear waste, from collection schemes that keep old gear out of the ocean to recycling initiatives that convert waste gear into new products. Progress has been significant, though challenges remain.

The Scale of the Problem

Australian commercial fishing uses millions of metres of rope, thousands of nets, and countless plastic buoys and floats annually. Some of this gear is lost accidentally during storms or snagging on the seafloor. Some reaches end-of-life and needs disposal. And unfortunately, some is deliberately abandoned when it becomes tangled or damaged.

In the past, fishing communities had limited options for disposing of old gear. Harbour waste facilities often don’t accept large quantities of fishing gear. Landfilling is expensive and available space limited. Burning creates air pollution. The result was that abandoned gear accumulated in harbours, got dumped at sea, or piled up at fishing ports creating hazards.

The environmental cost was substantial. Ghost nets continue fishing autonomously, catching fish, turtles, dolphins, and seabirds. Rope fragments are ingested by seabirds and marine animals. Plastic floats break down into microplastics that enter the food chain.

Quantifying the exact amount of Australian fishing gear entering the ocean is difficult, but estimates run to hundreds of tonnes annually. Some of this is genuinely accidental loss—fishing is a rough industry in harsh conditions, and gear sometimes breaks or is lost despite best efforts. But some is preventable through better gear management and disposal options.

Net Recycling Initiatives

Several Australian programs now collect and recycle fishing nets. The challenge is that fishing nets are complex plastics—typically nylon or polypropylene, often combined with other materials like metal chains or rubber components.

Early recycling attempts simply shredded nets and incorporated them into plastic lumber or other low-value products. This worked but didn’t create enough economic value to sustain collection programs. Fishers needed incentive to return old nets rather than discarding them, and that required end products with real market value.

More recent programs have developed higher-value recycling pathways. Some convert nets into nylon pellets that can be remanufactured into new products like carpets, clothing, or consumer goods. This creates value chains that make collection economically viable.

One successful model involves partnerships between fishing industry groups, recycling companies, and consumer brands. Brands commit to purchasing recycled fishing net material for their products. Recyclers pay for net collection based on this demand. Fishers receive a small payment or free disposal for nets they bring in.

The economics are still marginal—recycling fishing nets isn’t hugely profitable—but they’re workable with the right partnerships. Collection bins now exist at major fishing ports around Australia. Fishers can drop off old nets free of charge, knowing they’ll be recycled rather than landfilled or dumped.

Rope Recycling Programs

Fishing rope is easier to recycle than nets because it’s typically single-material polypropylene or nylon. Several Australian rope manufacturers now operate take-back programs where they collect old fishing rope and reprocess it into new rope or other products.

The volume of rope being recycled has increased significantly. What was a niche program five years ago now processes tonnes of rope monthly at some facilities. Collection points exist at most major fishing harbours, and some fishing companies have integrated rope recycling into their standard operations.

The environmental benefit is clear. Every tonne of rope recycled is a tonne that doesn’t end up in landfill or the ocean. And recycled rope production uses less energy and raw material than virgin rope manufacturing, reducing overall environmental footprint.

Challenges remain around contamination. Fishing rope gets fouled with barnacles, seaweed, salt, and fish remains. It’s often mixed with metal components like shackles or hooks. All this needs to be cleaned and separated before recycling, which adds cost and complexity.

Some programs have addressed this by asking fishers to remove obvious contamination before dropping off rope. Others have invested in industrial washing and separation equipment. The cleaner the input material, the higher quality the recycled output and the better the economics.

Buoy and Float Recycling

Plastic buoys and floats are among the most visible fishing gear waste. They wash up on beaches around Australia in large numbers, many originating from distant fishing operations carried by ocean currents.

Recycling buoys is challenging because they come in many shapes, sizes, and plastic types. Some are rigid polyethylene, others flexible PVC, and many contain foam or other materials. Sorting and processing this variety is labour-intensive.

Despite challenges, several beach cleanup organisations now collect and recycle buoys. Some are ground up and incorporated into recycled plastic products. Others are creatively reused—artists and craftspeople use old buoys in sculptures and functional objects.

The scale is still small compared to the number of buoys entering the ocean, but it’s growing. Some fishing industry groups are standardising buoy materials to make recycling easier in the future. If all buoys were made from the same recyclable plastic, collection and reprocessing would be much simpler.

Industry Engagement

Success of gear recycling programs depends heavily on fishing industry participation. Fishers need to actually use collection services rather than dumping old gear.

Several factors drive participation. Convenience is crucial—if dropping off old gear is easier than improper disposal, fishers will do it. Free or low-cost service helps, as fishing is a price-sensitive industry. And social pressure within fishing communities matters; when recycling becomes normalised behaviour, compliance increases.

Some fishing ports have made gear recycling part of their standard operations. Fishers returning to port can dispose of damaged or worn-out gear the same way they offload catch or refuel. This integration into normal workflows dramatically improves participation.

Industry groups have also helped by promoting gear recycling as good practice. When fishing associations endorse programs and encourage members to participate, uptake increases. This shifts recycling from an optional extra to expected behaviour.

Economic incentives help too. Some programs pay small amounts for returned gear, though the payments are usually modest. More important is avoiding disposal costs—in areas where fishing gear landfilling is expensive, free recycling is financially attractive.

Ghost Gear Recovery

Beyond recycling end-of-life fishing gear, several programs focus on recovering “ghost gear”—fishing equipment that’s already been lost at sea and continues catching marine life.

Recovering ghost gear is expensive and technically challenging. It requires locating lost equipment, which might be anywhere in vast ocean areas. Then divers or remotely operated vehicles must retrieve it, often from difficult locations like reefs or wrecks where nets snag.

Despite costs, ghost gear recovery programs operate in several Australian locations. Some focus on specific high-value areas like marine protected areas or important turtle habitat. Others work opportunistically, recovering gear when located during other diving operations.

Recovered ghost gear is typically recycled through the same pathways as end-of-life gear. The plastic isn’t degraded enough to prevent recycling—that’s part of the problem with fishing gear; it persists for decades in good enough condition to keep catching animals but not good enough for its intended use.

Funding for ghost gear recovery usually comes from grants and donations rather than commercial revenue. The environmental benefit is clear, but there’s no direct economic return from pulling abandoned nets off reefs.

Regulatory Support

Government regulation plays an important role in fishing gear management. Some jurisdictions have implemented gear marking requirements, so lost equipment can be traced back to specific vessels. This creates accountability and may reduce deliberate abandonment.

Extended producer responsibility schemes are being discussed, where gear manufacturers would be required to fund collection and recycling programs. This would shift costs from fishers and taxpayers to the companies profiting from gear sales.

Some areas have implemented deposit schemes for fishing gear—fishers pay a deposit when purchasing nets or rope, which they get back when returning the gear for recycling. This creates direct financial incentive for proper disposal.

Enforcement remains challenging. Monitoring fishing gear disposal is difficult, and penalties for improper disposal are often modest. Most programs rely more on industry cooperation than regulatory enforcement.

The Circular Economy Vision

The ultimate goal is creating a circular economy for fishing gear where old equipment is routinely recycled into new equipment or other valuable products. In this system, fishing gear never becomes waste—it just cycles through use, collection, recycling, and remanufacture.

We’re not there yet, but progress is real. Recycling infrastructure is expanding. Collection programs are becoming more comprehensive. Markets for recycled fishing gear plastic are developing.

Technology improvements help. Better sorting systems make mixed-material gear easier to recycle. Advanced cleaning processes handle contaminated gear more efficiently. Chemical recycling technologies can break down plastics that mechanical recycling can’t handle.

Consumer demand matters too. When outdoor clothing brands advertise products made from recycled fishing nets, they create market pull for collecting and recycling gear. This transforms waste management from a cost centre into a value chain.

What Still Needs Work

Despite progress, significant challenges remain. Many smaller fishing ports lack collection infrastructure. Fishers in remote areas have limited access to recycling programs. And the economics of gear recycling remain marginal without subsidies or brand partnerships.

International cooperation is needed since ocean currents carry fishing gear across national boundaries. Australian beaches receive gear from distant fishing operations. Addressing the problem comprehensively requires coordinated action across fishing nations.

Gear design also needs attention. If fishing equipment were designed from the outset for recyclability—using single materials, avoiding problematic additives, including markers for sorting—recycling would be much easier. But gear is currently designed primarily for function and cost, with recyclability an afterthought.

Still, the trajectory is positive. More fishing gear is being collected and recycled every year. Industry awareness is growing. Technology is improving. And the environmental case for keeping fishing gear out of the ocean is now widely accepted.

For ocean conservation, reducing fishing gear pollution may be one of the most tractable problems. Unlike microplastics from degrading consumer goods or plastic waste from developing nations with limited waste management infrastructure, fishing gear comes from a specific, regulatable industry. Solutions are technically feasible and economically viable with the right support structures.

Getting fishing gear recycling to the scale needed to meaningfully reduce ocean plastic pollution will require sustained effort, ongoing funding, and continued industry engagement. But we know it’s possible because it’s already happening, just not yet at sufficient scale.

Every net or rope recycled instead of lost at sea is a small victory for ocean health. Multiply those small victories across Australia’s fishing industry, and the impact becomes significant.
