:::What Is Fishery Waste?

Common fishery waste includes disused fishing nets (including buoys and ropes) and aquaculture Styrofoam.
Based on the data provided by the Fisheries Agency in 2018 on the recycling quantity in First Category fishing ports and the number of fishing boats, the annual output of disused fishing nets in Taiwan is estimated to be 2,300 metric tons. Common materials for fishing gear include nylon, polyester and PE. Fishing nets that have not degenerated beyond reuse can be properly sorted, with all accessories removed, and handed over to agencies for recycling and reproduction into regenerated plastic pellets

Aquaculture Styrofoam is mainly utilized for the floating method and long-line method of oyster farming. In contrast to disused fishing nets, the disused aquaculture Styrofoam is concentrated in such areas as Yunlin, Chiayi and Tainan (for the floating method) and Penghu County (for the long-line method). Based on the statistical data on aquaculture spawning provided by the Fisheries Agency on the enquiry platform, the total number of oyster floats used nationwide is estimated to be 20,297. A previous survey indicated that 14 pieces of Styrofoam were used per float, and each piece would last about 3 to 5 years, so an estimated 71,040 pieces of Styrofoam are discarded every year.

Recycling and Sorting Methods

Disused Fishing Nets


Before recycling, buoys and lead wires on the fishing nets should all be removed and properly sorted, which will make downstream agencies more willing to come for collection. Store the disused fishing nets in a centralized collection site within the fishing port. If there is no collection site within the fishing port, it is advised to regularly contact recycling agencies for collection on certain dates or when reaching a certain quantity.

Aquaculture Styrofoam


Fouling and biofouling (of seaweeds or shellfish for example) can occur during the use of aquaculture Styrofoam, most of which does not have reuse value and is sent directly to the incinerators. Only a small amount can be reused and handed over to recycling agencies for further treatment. The recycling and reuse methods include thermal melting and chemical treatment. Notably the chemical treatment is intended for lower-grade Styrofoam. To prevent Styrofoam from polluting the environment, alternative materials (e.g. EPP, hard PE and EVA) have been promoted in Tainan City, Penghu County and Chiayi County.

Processing and Reuse Methods

Using disused fishing nets as an example:
Processing procedures such as washing, crushing, thermal treatment and pressing can turn disused fishing nets into regenerated plastic pellets, and nylon can be threaded into textile yarns and reproduced into textile goods, e.g. garments, hats and backpacks.

Q&A

1.Can disused fishing nets be recycled?

Disused fishing gear is mostly made with plastic materials and can therefore be recycled and reproduced into plastic regrinds with wide applications. Fishermen are advised to preliminarily wash the old tattered fishing nets and remove any attached organisms and salt to reduce difficulties in handling them later.

2. Small quantities of disused materials that fail to meet the required minimum quantity for collection may cause environmental hygiene hazards. What can be done about such an issue?

Fishermen are advised to initiate a mutually beneficial practice of collective storage. Members of the same fishermen’s associations and fish markets can set up a shared storage space. The idea is that the quantity of disused materials can thus reach the required collection threshold within a short period of time; the materials with recycling value can be sold for a fee to contribute towards local development or maintenance, while the materials that cannot be sold can be handled by clearance and disposal agencies. Such a practice can effectively resolve the issue of local disused materials.
