Recycling Without Degassing - Israeli Producer Goes for Un-vented Model
In June, POLYSTAR installed a 250kg/hr plastic recycling system for the Israel-based LDPE plastic producer to recover its in-house waste generated from the production process including soft irrigation tapes.
The Israel-based plastic producer is the pioneer of drip and micro-irrigation products for agriculture, greenhouse, landscape, and mining applications.
The POLYSTAR plastic recycling system allows the plastic producer to recycle all of its waste generated in-house. The cutter compactor handles both scraps and on-roll waste efficiently and produces uniform-sized, high-quality recycled pellets, which are ready for immediate reprocessing. The gentle recycling process results in minimal material degradation without significant property change with reusability up to 100%.
Unvented Extruder: Ideal for Non-Printed Material
The Israel-based plastic producer chose POLYSTAR’s un-vented recycling machine model, which is ideal for clean and non-printed production waste.
Other suitable applications for the unvented material are unprinted film scraps and film on-roll waste from in-house blown and cast film production (stretch film, shrink film, OPP, CPP, BOPP).
Advantage
The unvented extruder has a very short screw L/D ratio, in which the material travels in the extruder for the shortest time and distance. This results in minimal material degradation (minimal change in material property) and slightly higher output compared to vented extruder. However, the limitation of the unvented system is that it does not have the capability of processing material with higher a printing percentage.
Today the Israeli company maintains 28 subsidiaries and 16 manufacturing plants worldwide and employs over 4,000 workers. The company's offering includes drippers, dripperlines, sprinklers, and micro-emitters. The company holds an over 30% share of the global drip irrigation market and is recognized as the world-leading provider of drippers and dripper lines. In-house Recycling has allowed the company to save up a significant percentage in raw material buying. The reclaim of valuable secondary raw materials not only reduces production costs but also keeps the production waste 100% clean and in-house.
