Ghost nets—abandoned fishing nets, are a major threat to the environment, marine life, and human activity. These nets don't degrade easily and continue to trap and kill fish, turtles, and seabirds, damaging the marine ecosystem. Made from plastics like nylon and PE, they can break down into microplastics that enter the food chain. Ghost nets also block fishing areas, disrupt operations, and can tangle ship propellers, creating safety hazards at sea.
Therefore, building a scientific and efficient ghost net shredding and recycling system is not only conducive to ecological protection, but also in line with the sustainable development strategy of resource recycling. The following are several common and environmentally friendly treatment methods:
Energy Recovery
If the ghost net is seriously polluted and cannot be recycled, energy recovery can be carried out by pyrolysis or incineration power generation. However, this method requires strict control of emissions to prevent secondary pollution to the environment.
Recycling and Reuse
Ghost nets are mostly made of high-strength plastics such as nylon and polyethylene, and have good recycling value. After cleaning, shredding and granulation, they can be used to produce recycled plastic products, such as clothing fabrics, carpets, backpacks, 3D printing materials, etc.
Mechanical Shredding + Resource Processing
Using industrial shredders to initially shred the fishing nets, and then deep processing through processes such as cleaning and melt granulation, can effectively improve processing efficiency and reduce labor costs, and is suitable for large-scale processing scenarios.
Among the disposal processes of ghost nets, the shredding process has become a key link. For those flexible, highly tough, and easy to entangle, it is recommended to use GEP ECOTECH's GDI series double-shaft industrial shredders, which have the following advantages:
- High torque and low-speed shearing design: effectively deal with the problem of fishing net entanglement, shredding evenly, and running stably.
- Customized cutter structure: Made of CrNiMo high-strength alloy steel, it has strong impact resistance and high wear resistance, and is designed specifically for flexible plastics.
- Anti-entanglement fixed cutter technology: effectively reduce downtime and loss caused by entanglement.
- Intelligent monitoring system: real-time monitoring of operating status, support automatic reversal, overload protection, and ensure equipment safety.
- Controllable discharge particle size: the discharge size range is 30-300mm, which can be adapted to subsequent cleaning, granulation and other processes.
- Wide output range: can cover 0.1~10 tons/hour processing needs to meet projects of different scales.
As a one of the top 3 solid waste disposal equipment manufacturers in China, GEP Intelligent Environmental Protection can provide you with suitable waste fishing net solutions. If the fishing net is relatively clean and free of large metal impurities, and the discharge particle size requirements are high (for recycling granulation, product processing, etc.), there are also single-shaft shredders to choose from.
