Herbold Meckesheim supplies fifth PET washing line to Doğa, Türkiye
In Kırklareli, in the European part of Türkiye, the latest recycling plant of the special machinery manufacturer Herbold Meckesheim is being built for the company Doğa. After commissioning, the washing line is expected to produce a daily output of 100 metric tons of PET recyclate. Doğa, a company hitherto active in the construction industry, intends to sell the recycled PET flakes for bottle-to-bottle applications.
“As the Doğa Group, we are proud to add the recycling sector to our activities of fields such as real estate, construction, mining and textiles,” explains Ömer Ayvacı, Chairman of the Board of the Doğa Group. “In today’s world, where the concepts of environmentally friendly production are becoming increasingly important, we aim to start rPET flakes production with completely environmentally friendly solutions with our state-of-the-art machinery park as of the beginning of next year.”
The special feature of Herbold’s latest recycling plant is that it also supplies key components for pre-sorting, such as a de-baler EWS 45/160 BA or a drum bottle wash unit HWTS 180/750. In terms of space, this section alone accounts for half of the plant layout. The actual cleaning process obeys state-of-the-art technology and starts with two force feeding granulators SMS 80/160-F7-2 SB3, the biggest in the Herbold portfolio. The hot washing and hydrocyclone stages, as well as the subsequent air separators, were designed for the required throughput. And three step dryers of the HVST 150/150 size are installed in the plant to achieve maximum capacity with minimum fines formation. In addition, the recycling line is equipped with an elaborated process water treatment.
Herbold Meckesheim has been part of Coperion’s Recycling Business Unit since last year. Together, the Stuttgart-based machinery and plant manufacturer and Herbold Meckesheim provide comprehensive overall solutions based on the complementary and aligned technologies of both companies. From mechanical processing, from size reduction, washing, separating, drying and agglomeration of plastics, through bulk material handling, feeding and extrusion, to compounding and pelletising, the business unit covers the entire process and thus value chain.
