PCR vs PIR: Understanding Recycled Plastic Classifications

What is PCR (Post-Consumer Recycled)?

PCR refers to plastic materials that have been used by consumers, discarded, and then recycled. Common sources include beverage bottles, detergent containers, food packaging, and daily-use product containers.

Characteristics of PCR

• Highest environmental benefit: Directly reduces plastic waste entering landfills or oceans
• High traceability requirements: Requires complete recycling chain proof (such as GRS certification)
• Greater quality variation: Due to complex sources, strict sorting and washing are required

What is PIR (Post-Industrial Recycled)?

PIR refers to the recycling of edge trims, defective products, or excess inventory generated during factory processes.

Characteristics of PIR

• Stable quality: Single source, properties close to virgin materials
• High cost-effectiveness: Simpler recycling process, usually lower price than PCR

Regardless of the choice, using recycled plastics is an important step toward a circular economy.
