Yes, PP (polypropylene) and PE (polyethylene) bottles can absolutely be recycled using a plastic extruder. In fact, extrusion is a core technology in the mechanical recycling process for these materials. The extruder melts, homogenizes, and filters the crushed and washed bottle flakes, which are then pelletized into high-quality recycled plastic granules. These pellets can be used to manufacture new plastic products, including bottles, films, pipes, and more.

Typical Recycling Process for PP/PE Bottles (Using an Extruder)

1. Sorting & Crushing – Bottles are sorted by plastic type (PP, PE, etc.) and fed into a crusher to produce small flakes.

2. Washing & Drying – Flakes are thoroughly washed to remove labels, adhesives, dirt, and residues, then dried.

3. Extrusion & Filtration – The clean, dry flakes are melted in a plastic extruder. A melt filter (screen changer) removes any remaining impurities.

4. Pelletizing – The purified melt is extruded into strands or directly pelletized using a plastic pelletizer (strand, water ring, or underwater pelletizer).

5. Cooling & Collection – The pellets are cooled, dried, and stored for reuse.
