Doğa PET doubles capacity at bottle washing plant
The second washing line scales daily output to 200 metric tons of rPET
Doğa PET has officially ordered a second PET washing line at its PET-flake based processing facility in Turkey. In collaboration with Herbold Meckesheim, a specialist in machinery and system solutions for plastic recycling, Doğa PET will double its existing washing capacity to produce a daily output of 200 metric tons of rPET flakes.
Expanding plastic flake production
The first washing line supplied by Herbold Meckesheim has been producing high-quality rPET flakes for two years. According to Doğa PET, stable operation and consistent output quality were the decisive factors behind the decision to invest in a second system. The new line is designed with the same core process layout and throughput parameters as the existing line, ensuring reliable scalability and operational consistency and features key technologies such as forced feeding granulators, hot wash system in batch design, and hydrocyclone density separation.
However, while the overall configuration of the new washing line corresponds with the proven design of the first plant, selected process modules have been optimized based on operational experience and variations in input 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 single machine. These adjustments aim to further stabilize throughput and efficiency.
Scaling systems with long-term collaborations
Preparations for the delivery of the second washing line are currently underway. The first shipments are scheduled for early March 2026. Installation and commissioning at the Doğa PET site are expected to start shortly thereafter. Herbold Meckesheim will support the project through all phases, from logistics coordination and on-site installation to system start-up and operator training.
"The first washing line has been running reliably since its commissioning and consistently delivers the product quality we require," said Ömer Ayvacı, Chairman of the Board of the Doğa Group. "Based on this positive experience, it was a logical step for us to expand capacity with a second line from Herbold Meckesheim."
"Repeat orders like this confirm that our customers value not only our technology, but also our role as a dependable project partner," said Stefan Lachenmayer, global commercial director recycling and managing director Herbold Meckesheim. "The second washing line for Doğa PET demonstrates how scalable system concepts can support long-term growth in plastics recycling."
