Extrusion International 6-2022

52 Extrusion International 6/2022 RECYCLING Bottle-to-Fibre and Bottle-to-Bottle – Two Starlinger PET Recycling Lines for Indian Recycling Brand Ganesha Ecopet Private Limited, a subsidiary of Indian PET recycling pioneer Ganesha Ecosphere Ltd., has recently opened its new Warangal facility under the brand name Go Rewise where it produces rPET for filament yarns and fibres, as well as for food-grade packaging. T he company has installed two Starlinger PET recycling lines in its facility inWarangal, Telangana state. Ganesha Ecopet plans to supply the produced rPET granulates under its newly introduced brand enterprise Go Rewise. Launched under the umbrella of one of India’s rPET industry leaders, Go Rewise is committed to supplying highest quality rPET products that are produced in a resource-efficient process. rPET for fibre applications The first Starlinger recycling line, a recoSTAR PET 165 H- VAC, processes washed PET bottle flakes for the Go Rewise polyester filament yarn applications and reaches an output of approx. 14,000 tons per year. When using recycled PET for filament yarn production, it must meet highest quality standards. Thus, all foreign particles and polymers have to be removed before the extrusion process. To achieve op- timum melt purity for extrusion, Starlinger has developed a special candle filter for fibre applications, called Rapid Sleeve Changer (RSC). It ensures finest melt filtration down to 15 μm and achieves a throughput of up to 2000 kg per hour. The filter elements can be changed without inter - rupting production, which significantly reduces melt loss and machine downtime. The RSC filter is a candle filter which Starlinger has developed especially for fibre and yarn applications. It ensures finest melt filtration down to 15 μm which is crucial in order to meet the quality requirements for polyester fibre production (Pictures © Starlinger)
