Do\u011fa Holding has diversified its investment portfolio within T\u00fcrkiye by making an impressive entry into the recycling sector. Do\u011fa PET, a subsidiary of Do\u011fa Holding, is using TOMRA\u2019s sensor-based sorting machines to produce premium quality PET flakes and rPET granules from post-consumer PET which are suitable for food and textile applications.\u00a0\u00a0<\/strong><\/p>\n\n\n\n

Located in northwestern T\u00fcrkiye, Do\u011fa PET\u2019s plant currently processes more than 4,200 tons of PET bottles monthly, producing 1,000 tons per month of PET flakes and 2,000 tons per month of rPET granules. The facility incorporates TOMRA\u2019s full range of machines for plastics sorting: four of the company\u2019s sorting all-rounder AUTOSORT\u2122<\/a>, as well as two INNOSORT\u2122 FLAKE<\/em><\/a> <\/em>and two AUTOSORT\u2122 FLAKE<\/em><\/a> <\/em>units for advanced flake sorting and purification. This combination of units optimizes both product quality and processing capacity.  <\/p>\n\n\n\n

Depending on Do\u011fa PET\u2019s customer requirements, the premium PET flakes \u2013 produced in various quality grades \u2013 are used for PET sheet production, while the rPET granules are mainly aimed at bottle-to-bottle recycling and high-quality textile applications. The company plans to export its recycled products, primarily to European countries.  <\/p>\n\n\n

Achieving exceptional purity levels with TOMRA technology  <\/h3>\n\n\n\n
\n

Dr. Sel\u00e7uk G\u00f6khan Gerlikhan, General Manager of Do\u011fa PET<\/strong>, comments: \u201cPET recycling has gained significant momentum in recent years. Instead of recycling PET waste into lower-value materials, it is crucial to use advanced technological infrastructure to recover it and produce materials with properties closely resembling those of virgin raw materials. TOMRA has been an invaluable partner since the start of this project. TOMRA\u2019s solutions are widely recognized as industry benchmarks by our customers, so we plan to invest in additional sorters as we develop our lines.\u201d\u00a0<\/p>\n\n\n\n

Commenting on the speed at which the plant achieved the targeted purity levels in its initial operations, Dr. Gerlikhan<\/strong> said: “We separate purity levels into two categories: polymer and color. Our target for polymer purity was 99.998% for the final product, and we achieved this. For color, our goal was to reach a purity level of 99% transparent PET in the final product. This includes reducing other colors, such as light blue PET, to below 1%. We have already exceeded expectations by achieving color variations below 0.5%.”\u00a0<\/p>\n<\/blockquote>\n\n\n

Minimizing loss of light blue PET material while maximizing purity in clear <\/h3>\n\n\n\n

While producing clear flakes, Do\u011fa PET aims to minimize the loss of light blue PET material and, when necessary, separates the light blue material from the clear one.  The blue bottles, which are ejected when processing clear PET, can be a valuable resource for other applications.  <\/p>\n\n\n\n

Do\u011fa PET is the first facility in T\u00fcrkiye to successfully separate light blue material from clear material, regardless of the infeed product. During the sorting process, light blue products are separated from all infeed materials and recovered for reuse as needed. <\/p>\n\n\n\n

\n

Serkan Orhan, Sales Manager for TOMRA Recycling<\/strong> Sorting in T\u00fcrkiye and the Middle East, explains the full process:\u00a0 “The plant\u2019s production line features four AUTOSORT\u2122 units which pre-sort the PET bottles. The first three sort by material and color before sending them to the subsequent crushing and washing line. The fourth AUTOSORT\u2122 unit re-sorts the rejected products from the first three units, sending recoverable materials back to the first AUTOSORT\u2122 to improve efficiency and material recovery.\u00a0\u00a0<\/p>\n\n\n\n

\u201cAfter pre-sorting, the material is crushed, washed and dried before being sorted by target colors using the INNOSORT\u2122\u00a0FLAKE<\/em>, TOMRA\u2019s highly flexible color and polymer flake sorting machine. Finally, the flakes are sent to the AUTOSORT\u2122\u00a0FLAKE\u00a0<\/em>unit, a specialist solution for high-end flake sorting applications such as food-grade bottle-to-bottle recycling. At this sorting stage, the targeted high purity is achieved thanks to the reliable separation of color, polymer and metal contaminants, virtually eliminating all traces of PVC, PC, PS and other unwanted polymers.\u201d\u00a0<\/p>\n<\/blockquote>\n\n\n\n

Advanced waste analysis  <\/h3>\n\n\n\n

Do\u011fa PET is required to prove that less than 5% of the input material for its washing process consists of non-food grade PET to produce food-grade pellets. To meet this requirement and enhance material recovery across its sorting lines, the company has invested in a state-of-the-art waste analyzer powered by PolyPerception<\/a>, a solution that uses cameras for real-time material analysis and classification at key points in the sorting plant. At Do\u011fa PET\u2019s plant, the analyzer is positioned before the last of four AUTOSORT\u2122 units. It continuously monitors and analyzes the quantity of non-food grade PET bottles destined for the washing line.  <\/p>\n\n\n\n

By providing data per batch or shift, the analyzer enables Do\u011fa PET to certify the food-grade quality of material from each specific production period, offering crucial reassurance to both its customers and relevant certification bodies. This transparency is particularly vital for end customers purchasing these pellets from a Turkish PET facility. Exporting its high-quality product to Europe, Do\u011fa PET relies on this assurance to meet its customers’ stringent compliance requirements. <\/p>\n\n\n

The crucial role of quality in filament-grade textiles <\/h3>\n\n\n\n

While Do\u011fa PET invests in high-quality food-grade rPET granules for bottle-to-bottle recycling, the company also applies the same approach to supplying raw materials for the textile industry. Dr. Gerlikhan comments: “The filament sector in textiles demands very high purity levels and color stability. The durability, aesthetics and functionality of the final fiber product depend heavily on the proper management of the PET recycling process when producing high-quality rPET granules. Accurate sorting is critical for increasing rPET granule purity. For us, using TOMRA’s state-of-the-art sorting systems is crucial as they ensure efficient and fast recycling processes.” <\/p>\n\n\n\n

Serkan Orhan<\/strong> concludes: \u201cWe are delighted to have been by Do\u011fa’s side from the very beginning on this project, consulting on the feasibility study. Achieving the desired capacity and quality levels in such a short period of time with such vast inputs has been a great achievement which demonstrates how advanced sorting technology contributes to achieving virgin-like material qualities.”\u00a0<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
