South Korea develops 4 kinds of microbially degradable fishing net materials

  • 2022-09-27

It is reported that Yizheng Chemical Fiber Bona Company has also carried out the research and development of fully biodegradable fishing nets. In addition, scientists at Cornell University in the United States have also developed a new environmentally friendly material called iPPO, which can be decomposed faster under ultraviolet light.


In order to reduce ghost fishing gear and protect the marine ecosystem, the National Academy of Fisheries of Korea has recently developed 4 kinds of microbially degradable fishing net materials.


Ghost fishing gear refers to the fishing gear that is discarded during the fishing process. It is generally made of plastic materials such as nylon. This material is difficult to decompose in a short time, and it is also easy to wrap around the necks and fins of marine life. Unable to breathe and eventually die.


The four materials newly developed by the National Academy of Fisheries are BEAS, PBEAS+AH, PBES, and Bio-PBS, which will be decomposed by microorganisms after a period of time in the sea, which can greatly reduce the resource loss and environmental pollution caused by ghost fishing gear.


In 2005, the National Academy of Fisheries first developed a microbially degradable crab net using PBS as a raw material, and popularized it on the fishing site. However, the fishing net made of this material is only suitable for fishing bamboo crabs, not for swimming crabs, yellow croakers, etc., and the price is 2-3 times higher than that of ordinary fishing gear.


Since 2016, the National Academy of Fisheries has started to develop more cost-effective fishing gear materials with a wider range of applications, and finally successfully developed the above four microbially degradable fishing net materials. The new material has improved toughness, softness, decomposability, environmental protection, etc., and the cost has also been reduced (5%). It will be effectively promoted and applied in reducing ghost fishing gear and protecting the environment.


The technology has been transferred to Ankor Bioplastics, a biodegradable plastics company that produces about 350 tons of biodegradable fishing net thread per year, which has been exported to the United States and is available on Amazon. The raw material for the new generation of fishing nets is PBEAS, a new biodegradable thermoplastic polymer. The replacement cycle for biodegradable fishing nets is about one year, which is shorter than the two-year cycle with nylon, but the new nets perform significantly better than previously developed prototypes. Note: The full name of PBEAS is polybutylene succinate co-butylene adipate co-ethylene succinate co-ethylene adipate, butylene succinate-butylene adipate-ethylene glycol succinate-ethylene glycol adipate copolymer.
ANKOR BIOPLASTICS

ANKOR BIOPLASTICS, formerly TLC Korea, was established in Gangwon-do, South Korea in 2012, and has long been engaged in the development of biodegradable materials PLA and PBS products.
In 2019, Vietnam An Phat Holdings invested in TLC Korea and changed its name to Ankor Bioplastics. It has also become the R&D center of Vietnam An Phat Holdings in the field of environmentally friendly materials and products.
ANKOR BIOPLASTICS has biodegradation and environmental protection certifications from Belgium OK COMPOST, Germany DIN and American BPI.
