Expert Tips for Buying Recycled Plastic: What are PCR and PIR?

When you buy recycled plastic, sellers will often ask if you want PCR or PIR. Here is the simple difference:

1. PCR (Post-Consumer Recycled Resin)

PCR comes from plastic products that people have used and thrown away (like plastic bottles or food packaging).These items are collected, sorted, washed very clean, and then made into new pellets.

• Large Supply: There is a lot of PCR available because everyone uses plastic every day.
• Cheaper Price: Usually, PCR costs less than PIR.
• The Challenge: Because the material usually contains more impurities, high-quality PCR depends heavily on the supplier's sorting and pelletizing technology.

2. PIR (Post-Industrial Recycled Resin)

PIR comes from factory waste. It is plastic that was never used by a customer (like NG products, edge trims…). Because it is usually very clean, it often doesn't need washing and can be made into pellets immediately.

• Pure Quality: The raw material comes from a single source in a controlled environment, making the recycling process simple and clean.
• The Challenge: The supply is less stable. You can only get PIR if a factory has waste.

Summary: Which one should you choose?

Many people think PIR is always better because it looks cleaner. However, if your factory needs a large and steady supply of material every month, PCR is the better choice.
