Reprocessing postindustrial (PIR) and post-consumer (PCR) scrap into functional products are essential in accomplishing environmental and fiscal sustainability.
Pelletizing: Ideal Solution for Reclaim and Reprocessing
While the benefits of pelletizing are wide reaching, such as streamlining material handling, transportation costs, storage requirements, process performance and repeatability, its greatest contribution may be reclaiming plastic waste -- closing the loop in the recycle process.
The most versatile single-screw extruder pelletizing systems are equipped with stuffer rams which feeds low bulk density feedstocks into the extruder. These cost-effective methods are applicable for PP, PS and PE low bulk density feedstocks (fluff, film, fiber, etc.).
Multi-resin Laminates and Versatile Dryerless Extrusion Systems
Converters who process multiple resins including PET, PETG, PLA, PP, PE, and PS benefit from an extrusion system with multi-resin capabilities. PTi's High-Vacuum Twin-Screw Extruder (HVTSE) Dryerless technology provides a robust multi-resin solution that allows virgin or recycled resin, such as PET or PLA to be processed without the need for drying and crystallizing. Additionally, HVTSE allows for reprocessing multi-resin laminates (i.e., PET with non-PET laminates such as PETG, PP, PE, EVOH, etc.), whereas most converters and municipalities treat hygroscopic multi-resin laminates as landfills. This eco-conscious manufacturing solution delivers major energy and cost savings, maximizes resin usage, and significantly reduces the carbon footprint, especially for hygroscopic resin conversion.
