Polyester Follows Fish from Sea to Table
Japanese company develops process for recycling polyester fishing nets.
announced development of a process aimed at diverting discarded polyester fishing nets from landfills, which add up to 1300 tons of waste/yr in Japan alone.
The process begins with the cleaning and drying of used fishing nets, which removes odors left over from its life at sea. Organic solvents are then used to remove coatings from the polyester. To improve heat resistance and durability, the polyester is processed with other recycled plastics. The resulting resin pellets can be used for products such as stationery and food trays.

Fittingly, the resin has found its first commercial application in a seafood restaurant. Tenjin is supplying a Japanese chain with plastic trays made from the recycled fishing net resin. The trays themselves are not yet recyclable, due to an anti-slip coating on their surface. Tenjin is working on technology to meet this challenge and allow them to be recycled despite the coating agent, with the aim of creating a circular product.
Tenjin Group has set a goal of recycling 1000 tons of fishing nets annually, by 2030.
