As global environmental awareness grows, the negative impact of plastic waste on the planet has drawn widespread attention. Against this backdrop, the production of PE recycled plastic pellets has emerged as a promising technology. By collecting and reprocessing polyethylene (PE) plastics, it offers a viable solution for plastic recycling. The manufacturing process involves several stages. First, discarded PE plastic products—such as bottles, bags, and containers—are collected from various sources. These wastes undergo preliminary cleaning and sorting to remove impurities and foreign materials.

Recycled plastic pellets, a subset of plastic materials, are produced by reprocessing used or discarded plastics through extrusion and pelletization. Graded based on raw material quality and processing characteristics, they are categorized into three levels. The production involves collecting waste plastics, reprocessing them, and pelletizing them. The grading system (Grade 1–3) reflects their diverse applications, making them valuable across multiple industries.
