What is Plastic Regrind and How is it Recycled?

Plastic regrind refers to recycled plastic material that has been shredded or ground into small pieces or granules by a shredder machine. It is typically derived from plastic waste, either post-industrial (scraps and leftovers from manufacturing processes) or post-consumer (plastic products discarded after use). This regrind material can be reused as a raw material in manufacturing new plastic products, making it an eco-friendly alternative to virgin plastic.

How is Plastic Regrind Produced?

Collection and Sorting: Plastic waste is collected from industrial or consumer sources and sorted by type (e.g., HDPE, PET, PP) and color to ensure material consistency.

Shredding/Grinding: The sorted plastic is fed into a plastic grinder or shredder, which reduces it into smaller pieces known as “regrind.” The size of the regrind material can vary depending on the recycling process and equipment used.

Cleaning: After grinding, the regrind material undergoes a thorough cleaning process to remove any contaminants such as dirt, grease, or labels. This can include washing and drying.

peletización (Optional): Some manufacturers further process plastic regrind into pellets by melting and extruding the material. These pellets are easier to handle and integrate into manufacturing processes.

Reuse in Manufacturing: The regrind or pellets are then used as raw materials to produce new plastic products, such as containers, pipes, automotive parts, or packaging materials.

Why Recycle Plastic into Regrind?

Environmental Benefits: Recycling plastic waste into regrind reduces the need for virgin plastic production, conserving natural resources like oil and gas. It also minimizes landfill waste and lowers greenhouse gas emissions.

Cost Efficiency: Using regrind plastic is often cheaper than sourcing virgin plastic, making it a cost-effective choice for manufacturers.

Sustainability: Plastic regrind promotes a circular economy, where materials are reused and repurposed rather than discarded after a single use.

Applications of Plastic Regrind

• Injection Molding: Regrind can be used to manufacture parts for the automotive, consumer goods, and electronics industries.
• Blow Molding: Used for making bottles, containers, and packaging materials.
• Extrusion: Regrind is used in producing pipes, profiles, and sheets.
