The Versatile World of Recycled Plastic Granules: Understanding the Recycling Process

For recycled plastic granules to be produced, used plastic materials first need to go through an intensive recycling process. Old plastic bottles, packaging, and other items are collected through municipal curbside programs or drop-off locations. The mixed plastics are then sorted by resin type to separate items like PET, HDPE, LDPE, and PP. Any non-plastic contaminants like paper, metal, or food waste are removed through advanced sorting technology.

The clean plastic flakes are then washed, shredded, and melted down in an extrusion process. High temperatures and pressure are applied to break the plastic back down into a liquid state. From there, the molten plastic is formed into uniform plastic pellets called Recycled Plastic Granules. These granules retain the same properties as the original resins and can be remanufactured into new plastic products through injection molding or other forming methods.

Variety of Applications

RPG have a diverse range of uses across many industries. Plastic lumber or decking materials are often made from recycled HDPE and PP granules. These synthetic wood alternatives are more durable and environmentally friendly than pressure treated wood. Flooring tiles, road surfaces, railroad ties and park benches can likewise incorporate recycled plastic content.
