Sustainable in many different ways: recycling at Trevira
As an industrial enterprise, Trevira is conscious of its special responsibility for an intact environment and has long advocated the recycling of valuable raw materials and waste products. Trevira CEO Klaus Holz: “We at Trevira wish to preserve the environment and at the same time work to create value. These are the criteria of our sustainability concept.“
Creation of the new brand is therefore only a logical step, one that enables customers to label their sustainable Trevira products as such. Trevira is known for the high quality of its products. In every way recycled products are as good as the original materials in terms of quality and performance.
Two vital elements in Pre-Consumer Recycling and an important concept in Post-Consumer Recycling form part of the sustainability strategy of Trevira to conserve resources and maintain value. :
In the area of Pre-Consumer Recycling, on the one hand, residual materials resulting from the manufacture of polyester fibres and filaments in Bobingen and Guben, dependent on the manufacturing step, are processed in the agglomeration plant and restored to become serviceable primary material. The recyclates are then fed back to the fibre and filament spinning mills, to be made into new top-quality products.
On the other hand, in fibre production there occurs in the manufacture of tow a small proportion of tow that cannot be used for converting and has to be cut out. Instead of selling this material as waste, it is cut up, pressed into balls and then carded / combed by a partner, resulting in a 1A quality product. The GRS certification (Global Recycled Standard) is requested for this. As with converter tow from new material, the recycled tow is mostly incorporated into polyester wool blends (55 % PET / 45 % wool), which are used primarily in corporate wear and uniforms.
In the area of Post-Consumer Recycling, Trevira offers filament yarns consisting of 100 % recycled PET bottles. Parent company Indorama manufactures very high quality recycled chips from PET bottles. Since only transparent PET bottles are used in Thailand, the flakes and chips are of a particularly good and very uniform quality. The recycled chips, fibres and filaments from Indorama bear the GRS certificates (Global Recycled Standard) and RCS-NL (Recycled Claim Standard). Trevira processes the regranulate made by Indorama from bottle flakes into filament yarns consisting 100 % of recycled material. The filament yarns are available in titres 167 and 76 dtex normal polyester. Alongside technical applications, they are used in the automotive and apparel sectors. In addition, many promising developments with the recycled material are on their way.
