• Four Reasons Why Manufacturers Should Start Recycling In-House Plastic Waste

  This article explains the importance of in-house plastic recycling (Post-Industrial Recycling, PIR) for manufacturers. By converting production scrap such as films, bags, and injection molding waste into reusable pellets, companies can reduce material costs, improve quality control, and support circular economy goals. In-house recycling also minimizes outsourcing expenses, lowers carbon footprint, and creates additional economic value by transforming plastic waste into marketable raw materials.

• How To Choose The Right Laboratory Extruder for Your Application

  Laboratory pelletizing extruders are compact, high-precision machines designed for polymer research, formulation development, pilot production, and small-batch pellet manufacturing. They operate using the same principles as industrial extrusion systems but provide greater flexibility, lower material consumption, and precise process control. These machines support applications such as polymer compounding, masterbatch production, biodegradable material development, and reactive extrusion. By enabling accurate testing of screw configurations, temperature profiles, and processing parameters, laboratory pelletizing extruders serve as a critical bridge between material development and full-scale industrial pellet production.
