Plastic Recycling for Injection Molding Companies

By Seraphim Plastics | April 11, 2026

Injection molding facilities generate consistent, high-quality plastic scrap—often in the form of runners, sprues, rejected parts, and purged material. Instead of treating this as waste, leading manufacturers are turning it into a revenue stream and operational advantage.

What Scrap Comes from Injection Molding?

  • HDPE, PP, PET, ABS, Nylon
  • Start-up purge material
  • Off-spec parts
  • Color change scrap

Because this material is often clean and consistent, it’s among the most valuable scrap in the recycling market.

Regrind vs Selling Scrap

Manufacturers often ask: Should we reuse or sell?

Regrind advantages:

  • Immediate reuse
  • Reduced raw material costs

Selling advantages:

  • Avoids contamination risks
  • Maintains product quality standards
  • Generates direct revenue

👉 Many companies do both: reuse internally where possible and sell excess material to a plastic scrap buyer like Seraphim Plastics.

How to Maximize Scrap Value

  • Separate by resin type (HDPE, PP, etc.)
  • Keep natural (uncolored) material separate
  • Avoid mixing contaminated scrap
  • Store properly in Gaylords or bins

Why Work with a Scrap Buyer?

  • Injection molding scrap
  • Post-industrial plastics
  • Bulk loads from manufacturers

They offer:

  • Pickup services
  • Competitive pricing
