How to Set Up a Closed-Loop Recycling System

By Seraphim Plastics | April 25, 2026

A closed-loop system allows manufacturers to reuse or recycle their plastic waste internally or through partners.

What Is Closed-Loop Recycling?

A system where plastic waste is:

  1. Collected
  2. Processed
  3. Reused in production

Benefits

  • Reduces raw material costs
  • Improves sustainability
  • Minimizes waste disposal

Steps to Implement

1. Audit Your Waste

Identify:

  • Scrap types
  • Volumes
  • Contamination sources

2. Separate Materials

Avoid mixing:

  • Different resins
  • Colors
  • Contaminated scrap

3. Choose a Recycling Strategy

  • Internal regrind
  • External recycling partner

4. Partner with a Buyer

Seraphim Plastics can handle excess material that cannot be reused internally.

👉 A hybrid model (reuse + sell) often works best.
