One of the world’s biggest yarn producers, Korteks, has started the production of recycled polyester (rPET) filament yarn in its production site using a Starlinger recycling line. The Starlinger recoSTAR universal 165 H-VAC iV+, which is part of the US$ 10 million investment by Korteks Mensucat San. Ve Tic. A.S., Bursa/Turkey, in a new polymer recycling facility, took up operation in May 2021.

The recycling line from Starlinger & Co Ges.m.b.H., Vienna/Austria, is the first of its kind in Turkey. An RSC (Rapid Sleeve Changer) candle filter ensures finest melt filtration down to 15 μm. Specially designed for PET recycling, it reaches an output of 1,000 kg/h. For continuous operation the filter elements are changed “on the fly” without interrupting production. The viscoSTAR SSP unit at the end of the recycling process guarantees consistent IV increase according to the first-in-first-out principle. The technical configuration of the line allows the processing of a PET fiber/PET flake mix as input materials, and also 100% PET filament scrap or 100% PET bottle flakes.

With the new recycling facility, which comprises a total closed area of 17,000 m² and has a monthly production capacity of 600 tons, Korteks was able to reduce the production waste at its virgin PET yarn site to zero. It has a production capacity of 7,200 tons/year and currently processes clean in-house PET fibers from production scrap together with washed post-consumer PET flakes.
