Extrusion International 2-2026

40 Extrusion International 2/2026 RECYCLING Second PET Washing Line Delivered in the T ü rkiye H erbold Meckesheim, a specialist in machinery and system solu- tions for plastics recycling, has been commissioned by Turkish recycling company Doğa PET to deliver a sec - ond PET bottle washing line. The order follows the successful opera- tion of the rst washing line, which has been in continuous operation since the rst quarter of 2024. With the new installation, Doğa PET will double its existing washing capac- ity at its recycling site in Kırklareli, Türkiye to produce a daily output of 200 metric tons of rPET akes. The project underlines the con dence placed in Herbold Meckesheim as a system supplier and long-term technology partner for complex re- cycling applications. Proven Performance Drives Expansion Decision The rst washing line supplied by Herbold Meckesheim has been producing high-quality rPET akes for two years. According to the cus- tomer, stable operation and consis- tent output quality were the deci- sive factors behind the decision to invest in a second, technically identi- cal system. The new line is designed with the same core process layout and throughput parameters as the existing line, ensuring reliable scal- ability and operational consistency and features key technologies such as forced feeding granulators, hot wash system in batch design, and hy- drocyclone density separation. How- ever, while the overall con guration of the newwashing line corresponds with the proven design of the rst plant, selected process modules have been optimized based on operation- al experience and variations in in- put material composition. A further improvement is the increase in pre- sorting capacity to 8.0 t/h. To achieve this, Herbold is supplying a debaler and a washing drum that integrates both wet and dry sections into a sin- gle machine. These adjustments aim to further stabilize throughput and ef ciency. Herbold Meckesheim will support the project through all phases, from logistics coordination and on-site installation to system start-up and operator training. “The rst washing line has been running reliably since its commis- sioning and consistently delivers The two SMS forced feeding granulators installed in the rst line ensure uniform ake size and stable material intake, creating ideal conditions for downstream washing and density separation processes (Photos: Herbold Meckesheim, Germany) As a central process stage within the PET washing line, the hot wash system in batch design enables controlled temperature management and de ned dwell times for ef cient removal of labels, adhesives and organic residues
