PET flake sorting system helps German recycler reduce waste volume
Continuously falling global prices for low-grade PET lead to development of new solutions for PET waste
BTB PET-Recycling GmbH & Co. KG, established in the year 2006, and headquartered in Bad Salzuflen (North Rhine-Westphalia), Germany, recently installed a new PET flake sorting system from Sesotec. BTB PET-Recycling processes approx. 20,000 tons of PET bottles per year. The owner-managed company, with about 30 employees, primarily produces PET granulate both for bottle-to-bottle and for foil manufacturers.
The PET bottles to be processed undergo a preparation process of several steps before they, as PET flakes, pass through the newly installed Sesotec flake sorting system. This system comprises a new chute machine of type FLAKE PURIFIER CM 1536 and an already existing belt machine from the year 2011, which after modification could be integrated in the new installation.
Sesotec, in addition to the optical sorters, also supplied BTB PET-Recycling with the system's steel construction, pneumatic conveying technology, and control technology. The objective of this, according to Sesotec, was to better coordinate the work that had to be performed, and to shorten the down-time of the complete plant in the construction phase.
"Because of continuously falling prices for low-grade PET material on the Asian market we had to develop new economic solutions for PET waste, and our strategy was to reduce the waste volume", says BTB plant manager, Mr. Zajontz. "With the new installation of the Sesotec sorting system we have reached this objective. There is no question regarding the profitability of the system."
"The integration of remote access makes it possible to monitor the sorting system through the network," added Zajontz. "Sesotec service engineers also can use remote diagnostics for short-term error remedying or for software updates, which makes processes in everyday operations much easier. Cooperation with Sesotec was smooth right from the start."
