Starlinger: Focus on film recycling – and two world premieres

Starlinger recycling technology will be in Hall 9, showing a recoSTAR dynamic recycling line in operation, reprocessing in-house film waste. The SMART feeder, one of the line’s most important components, prepares the input material: Its automatic temperature control makes it possible to achieve uniform high product quality even when processing materials with varying moisture levels and fluctuating bulk density. Also, all recoSTAR dynamic lines are equipped with the “Dynamic Automation Package” DAP and the rECO energy concept. Continuous process adjustment, the use of motors of the highest energy efficiency class, and energy recuperation at various process steps make this one of the most efficient plastics recycling lines on the market, in terms of both production and energy efficiency. 

In addition, Starlinger recycling technology will be presenting two world “firsts” at this year’s K exhibition: new technology for processing polyester, and a pioneering process for refinement of pellet material.

High-tenacity polyester fiber recycling: A challenge tackled with innovative technology

To produce man-made fibers and filaments, several polymers such as PES (polyester), PP, PA, and others, are available. The choice depends on the application: PES fiber, for example, is used as staple fiber (PSF - Polyester Staple Fiber), filament (POY - Partially Oriented Yarn, DTY - Drawn Textured Yarn, FDY - Fully Drawn Yarn), technical yarn and tire cord, monofilament, as well as nonwoven and spunbond.
Due to its characteristics polyester is used for the production of various apparel products. It does not wrinkle, stretch or shrink, and is resistant to abrasion, which makes it perfect for garments such as pants, shirts or suits; it can be easily washed and is quick drying, thus many materials for home furnishing are made of polyester. Outerwear often contains polyester due to its durability and ability to withstand strong and repetitive movements, and because polyester is hydrophobic, it is suitable for damp and wet environments.

Recycling and reuse of PES fiber and fabric scrap

The growing popularity of polyester fibers in garment production becomes evident in the increase of the annual polyester fiber and filament production from 20 million t in 2002 to more than 48 million t in 2015, and is forecast to reach around 55 million t by 2020. This also means that the amount of scrap generated during polyester fiber and fabric production is growing accordingly. More and more fiber producers and plastics recyclers have started to recycle fiber and fabric scrap from industrial production and post-consumer collection. rPES produced both from fiber/fabric scrap and post-consumer PET bottle collection is currently being used at a rate of 14.4 % in polyester fiber production, mostly for polyester staple fiber. China is by far the greatest user of rPET from bottle flakes in fibers, processing almost 80 % of the 7 million tons produced worldwide in 2015.

Many brand owners have started to integrate rPET in their products as part of their sustainability strategy, following increasing demand from consumers for "green" products. Also, the use of recycled granulate helped to reduce material costs significantly in the past years, creating an additional incentive for both polyester producers and recyclers. Currently however, low prices for virgin material are pressuring margins for recycled material.

Recycling challenges with high-tenacity fibers and fabrics

High-tenacity polyester fibers feature low water absorption and minimal shrinkage in comparison to other industrial fibers. They are used for threads and ropes, safety belts, etc. Tenacity is the general measure of the specific strength of a fiber or yarn, also called strength-to-weight ratio.

Challenges in recycling:

• Humidity: different production steps cause different levels of humidity (incl. spin finish) - special precautions must be taken.
• Material comes in bales, lumps, fabric, ...; due to the exceptionally high strength of the material it is very tough and requires shredding in a single-shaft cutter.
• Requirements for color values allow no oxidative or thermal degradation.

The reuse rate lies usually around up to 30 %, in the same application it can reach up to 100 %.

Selecting the correct recycling equipment

The input material and intended use of the regranulate are important factors for choosing the right recycling equipment. High-tenacity PES fiber recycling applications demand special machine features such as pre-shredding, drying before extrusion, high-vacuum degassing and fine melt filtration. Also, solid stating for IV increase in the produced pellets may be necessary to achieve the characteristics required for reuse.

Starlinger's recycling lines for PES fiber recycling - the recoSTAR dynamic (the successor model of the recoSTAR basic recycling line) and recoSTAR universal recycling lines - have been installed for a number of high-tenacity fiber recycling applications worldwide. High automation, increased energy efficiency and a wide range of applications are the key highlights of the recoSTAR dynamic technology. In the SMART feeder, a rotating disc at the bottom cuts the input material and creates friction. This frictional process heats and dries the mixed material, densifies it and brings it close to the melting point before it is fed into the extruder. Six extruder sizes from 150 - 2,600 kg/h (output with degassing) are available.

Versatile, accessible, and equipped with intelligent features: The recoSTAR universal recycling line is perfect for processing hard-to-grind materials such as bales, fibers, fabrics and start-up lumps. In the ACTIVE shredder arranged parallel to the extruder a hydraulic pusher presses the material against a water-cooled rotating shaft and thus provides efficient crushing. In combination with the sophisticated software and the dosing screw, this kind of material preparation allows the processing of materials with different bulk densities without having to change process parameters. Five extruder sizes from 150 - 1,300kg/h (output with degassing) are available.

Both lines feature high-vacuum degassing for PES recycling to ensure the effective removal of volatile contaminants such as additives and finishing agents. Concerning filtration, reuse and the required filtration fineness at the production line are determining factors; standard filter fineness is 50 µm, fine filtration (25 µm) with cascade filter system is also possible. The type of pelletizer is mostly a question of which pellets shape of the rPET is preferred - both (automatic) strand pelletising or underwater pelletising are possible. Special features are inline viscosity and colour measurement. Optionally, crystallisation and solid-stating of PET pellets and flakes can be included.

recoSTAR dynamic 215: New machine size scores big on manpower savings, energy efficiency

Starlinger recycling technology unveiled its new plastics recycling line recoSTAR dynamic 215 for a select group of prospective customers on June 7, 2016 at the Starlinger factory in Weissenbach an der Triesting, Austria.
‟With this line we have again increased our capacity range for polyolefin recycling,” states Paul Niedl, head of sales for Starlinger recycling technology. ‟The recoSTAR dynamic 215 was purpose-built to customer specifications regarding output and minimised operator involvement. The high degree of automation makes it possible to operate even a line of this size with the same personnel as the smaller lines, working efficiently with minimum energy consumption.”  

With its output range of 2,200 to 2,600 kg/h and power requirement of 0.2 to 0.35 kWh/kg, the recoSTAR dynamic 215 is one of the most energy-efficient lines on the market. To achieve this, Starlinger recycling technology developed the “rECO” concept for optimum energy use: Only the most energy-efficient motors are used, energy recuperation systems are integrated into various process steps, and the extruder barrel is heated with infrared emitters. In addition, the Dynamic Automation Package (DAP) developed by Starlinger keeps the line working at the optimum operating point, thereby maintaining not only constant production of consistent quality pellets, higher output and greater flexibility in material processing, but also reducing energy consumption. Together with the “rECO” concept, this realises energy savings in excess of 10 %.  

The first recoSTAR dynamic 215 recycling line with integrated C-VAC module will be supplied to a customer in Spain, where it will be used for reprocessing post-consumer EPS packaging waste. In test runs with this material, a throughput rate of over 2,800 kg/h was achieved.  

The recoSTAR dynamic recycling lines are capable of processing a wide range of plastics and are especially suitable for moist, hygroscopic or highly contaminated input materials. Depending on the line configuration, plastic waste with up to 25 % moisture can be recycled. By integrating the optional C-VAC high-capacity degassing module into the line, even heavily printed or heavily soiled input materials such as post-consumer plastic waste or agricultural films can be reprocessed into valuable secondary material.
