Carbios: Polyester recycling with new textile preparation line

Carbios inaugurated its textile preparation line at its demonstration plant in Clermont-Ferrand, in the presence of Mr. Lescure, French Minister for Industry. To streamline the textile preparation phase, which is currently carried out by hand or on several lines, Carbios has developed a fully integrated and automated line that transforms textile waste from used garments or cutting scraps into raw material suitable for depolymerization with its enzymatic biorecycling process. This patented line integrates all preparation stages (shredding and extraction of hard points such as buttons or fasteners), and provides Carbios with a high-performance, scalable development tool. The platform will help validate the biorecycling technology for textiles at demonstration plant scale (by 2024), and provides Carbios with expertise in working with collection and sorting operators to specify the quality of textiles and the preparation steps needed to make them suitable for enzymatic recycling. This expertise will also be invaluable to brands in the eco-design of their products.

Current collection, sorting and preparation infrastructures limit the amount of textile waste available for “fiber-to-fiber” recycling. Collection rates average around 15-25% worldwide[1], and much of the waste collected is exported to Africa, Asia or Latin America for sorting.

Moreover, textiles are highly complex materials, with yarns of different composition (or nature) that are difficult, if not impossible, to physically separate. However, the highly selective enzyme developed by Carbios can specifically depolymerize the PET (polyester) present in textile material.

At present, textiles are sorted and prepared mainly by hand, with low yields, particularly for disruptors to recycling processes such as “hard points” (zips, buttons, etc.). To optimize this crucial phase, Carbios is contributing a textile preparation solution to accelerate the development of biorecycling in the textile industry. Enzymatic recycling, or biorecycling, therefore contributes to the construction of a textile recycling chain and the acceleration of textile circularity, also enabling brands to do away with used bottles.

Polyester recycling: Thai Polyester ordered four VacuFil recycling systems from BB Engineering

BB Engineering GmbH (Germany), a subsidiary of Oerlikon Textile, is pleased to announce that Thai Polyester Co., Ltd (Thailand) has placed a major order for four VacuFil systems for recycling bottle flakes with connected direct spinning. The polyester manufacturer, established in 2001 and with an overall annual capacity of 316,800 tons, is one of Thailand’s leading producers and exclusively uses German technology. To this end, the company already operates Oerlikon Barmag and Oerlikon Neumag systems. The BB Engineer-ing VacuFil systems will be deployed to convert existing spinning plant equipment from processing polyester to processing PET bottle flakes without loss of performance.

BB Engineering supplies the complete recycling process – from the drying stage and extrusion, all the way through to the spinning plant-appropriate fine filtration stage. Thanks to decades of experi-ence in spinning plant technology, the German machine construc-tor also provides comprehensive spinning plant know-how and is aware of how the recycling process must be designed to ensure that the product manufactured using the spinning plant ultimately has the right quality. The four new VacuFil systems will be integrated into the existing building infrastructure and process landscape at Thai Polyester, with a total output of approx. 4,000 kg/h. The Vacu-Fil systems will be complemented by BB Engineering 3DD mixers for directly feeding dyes into the recycled melt flow. Commissioning has been scheduled for 2023.

Thai Polyester will be using the new VacuFil systems to manufac-ture its ‘EcoTPC’ recycling-brand yarns. 100% of these polyester yarns are produced from bottle, fiber and yarn waste and are all GRS certified.

Recycled polyester filament yarn made in Turkey

Korteks, one of the world’s biggest yarn producers based in Bursa, Turkey, has started the production of recycled polyester filament yarn in its production facility using a Starlinger recycling line.

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 PES yarn site to zero.

The Starlinger recoSTAR universal 165 H-VAC iV+, which is part of Korteks’ 10 million dollars investment in a new polymer recycling facility, took up operation in May 2021. It has a production capacity of 7,200 tons per year and currently processes clean in-house polyester fibers from production scrap together with washed post-consumer PET flakes at a ratio of 50/50. Korteks uses the polyester regranulate at a share of 100 % for its new polyester filament yarn line it is going to market under the name “TAÇ Reborn”. With this investment, the company has made an important step towards establishing a circular economy in the Turkish textile industry.

With this investment, the company has made an important step towards establishing a circular economy in the Turkish textile industry.

The Starlinger recycling line is the first of its kind in Turkey and is equipped with special components for filament yarn recycling. A RSC (Rapid Sleeve Changer) candle filter developed by Starlinger ensures finest melt filtration down to 15 μm. It has been specially designed for polyester recycling and reaches an output of 1000 kg/h. For continuous operation the filter elements are changed “on the fly” without interrupting production, which significantly limits melt loss.

The viscoSTAR SSP unit at the end of the recycling process guarantees consistent IV increase according to the first-in-first-out principle. This makes sure that the produced regranulate has the ideal properties required for filament yarn production. The technical configuration of the line does not only allow the processing of a polyester fiber/PET flake mix as input materials, but also 100 % polyester filament scrap or 100 % PET bottle flakes.

Korteks expects the recycling market in general to grow as there is increased acceptance for recycled products in the society, and predicts the need for recycling solutions also for other synthetic and natural fibers.
