Sweden Post-Consumer Recycler Intelligent Recycling with POLYSTAR Repro-Direct

The Sweden reputed recycler, which is the professional recycler and collects plastics from waste electrical and electronic equipment (WEEE) and other products from the automotive sector such as bumpers, battery packs, engine piping, etc. These Post-Consumer waste are contained with iron particles, wood pieces and paper labels…etc. Thus, the turnkey solution from the material sorting, cleaning, drying and processing into the high end quality recycled pellets are the essential factors toward business success. Thanks to the simplest yet powerful design of POLYSTAR’s recycling machine, plus integrate with FIMIC’s advanced auto cleaning filtration system. It ensures the excellent filtration efficiency and continuously high output performance.

The collected post-consumer ABS and PS regrind have the higher bulk density of 200-600 kg/m3 and is with more fluidity. Both properties contribute to the washing and sorting processes working better and the material thus being available in a more clean-sorted form. Meanwhile, POLYSTAR customize the tailor-made screw profile design which is optimized the melting flow paths and activities for both materials, and the specific pelletizing die head design is also beneficial for stabilizing the quality and consistency of the pelletizing process. Moreover, the customer request the intelligent water level sensing control on the vibration tank to optimize the cooling efficiency in time. With POLYSTAR simplified and user-friendly structure design, the cooling temperature can be visible monitored and controlled via intelligent PLC control system, the average output of its Repro Direct 150 is reached up to 700~800 kg/hr for our business benefit constant contribution, impressively described by the factory director.

As a professional recycler in the post consumer recycling industry, the excellent quality of the recycled pellets and high efficiency of machinery operation are the most important two indicators we pursue. Hence, we consider that the simplest yet powerful machine of POLYSTAR, and its high degree of fully automation control system can be met with our expectation, says by the customer. By adopting with SIEMENS state of art PLC plus POLYSTAR intelligent HMI touch panel control system, the energy and current consumption can be monitored in-time, and the feeding, cutter compacting, extrusion, filtration, pelletizing units are flexible switched control and data setting precisely. The other value-added functionality of this smart PLC control system including as below:

1. Preheating sequence of the extruder temperature for higher degree of automation.
2. Process parameter data setting ,recording and simulation
3. Operation data curve analysis
4. Operation error alarm and in-time report

For processing the post consumer grade waste material, the efficiency of filtration system should be the critical factors for the higher quality and stable throughput. After comparison of several advanced melt filter solution by the client itself, they finally choose Italian FIMIC auto-cleaning filtration system as the higher cost effective solution. Thanks to the similar “ Simple yet Powerful” design concept and mentality of FIMIC. It can be perfectly integrated with POLYSTAR recycling line and perform the best filtration capability via mutual technical cooperation. The major advantage and core value of FIMIC auto-cleaning filtration system is indicated as below:

．Lower Sensitivity: The scraper collects immediately the contaminations from the screen and avoid the contamination permanence or damage to the screen.

．Lower Maintenance Cost: The cost of spare parts are approximately 5 time less expensive than other suppliers.

．Easier Operation: Simplified configuration structure design, need only 30 minutes and one operator to replace a screen efficiently.

．Less Production Loss: As a general rule, the max. melt losses with FIMIC technology only reach to 0,5% - 1%.

．Specific Valve Discharging Technology: The valve can be automatically adjusted according to the amount of contamination accumulated, to ensures the maximum clean melt material keeping inside.

After converting the home appliance waste into recycled pellets, Degree of degradation is the major concern. Thus, the customer put back the recycled pellets into the injection molding machine for production and verify the impact resistance, tensile strength and flexural strength of the end product. As a result, the quality is met with our criteria and expectation, POLYSTAR proven its merits not only at its machinery, but also with the excellent quality of recycled pellets. A proportion of the recycled pellets will be mixed with the confidential additives and powder formulation into compounding process and develop the reinforced material for high-value market. We are committed to maximizing waste utilization and afford the social responsibility for global environment protection, emphasized by the customer.
