Recycled plastic is a plastic raw material obtained by processing waste plastic through physical or chemical methods. Specifically, recycled plastic refers to plastic raw materials obtained by processing waste plastic through physical or chemical methods such as pretreatment, melt granulation, and modification. It represents the reuse of plastic.

The processing of recycled plastic typically involves the following steps:
Pretreatment: This includes cleaning and sorting to ensure the waste plastic is clean and classified.
Melt granulation: The pretreated plastic is melted and granulated to form reusable plastic pellets.
Modification: As needed, the plastic pellets are modified to improve their properties.

Recycled plastic can be widely used in many fields, including:
Textiles: Used to produce fibers and textiles.
Food and beverage packaging: Used to produce various packaging materials, such as beverage bottles and food packaging bags.
Home building materials: Used to manufacture furniture and building materials.

In recent years, China has continuously strengthened the recycling and utilization of plastic waste, issuing a series of policies to promote the development of the recycled plastic industry. For example, the Guiding Opinions on Accelerating the Establishment and Improvement of a Green, Low-carbon and Circular Development Economic System, issued by the State Council in 2021, proposes the construction of a waste material recycling system and strengthening the recycling and utilization of recycled plastic resources.
