Regrind

Also called: Grinding, ground scrap, crushed plastic, mill

Regrind is plastic scrap that has been ground into irregular pieces, ready to be mixed with granules or reprocessed without re-pelletising.

Regrind is plastic scrap, such as moulded parts, rejects, runners or post-consumer items, that has been shredded or ground in a granulator into irregular chips. It has not been melted and re-pelletised, so it keeps the shape of cut pieces rather than uniform pellets.

Why it matters when buying recycled plastic

• Regrind is usually cheaper than granules because it skips the melting step, but it is less uniform.
• Feeding can be uneven if particle size varies or contains many fines and dust; ask for screen size and dust level.
• Clean single-source post-industrial regrind is often reliable enough to mix directly with virgin or recycled granules.
• Post-consumer regrind may need washing and inspection for contamination.

Common uses

Regrind is mixed in a set proportion with granules for injection moulding and extrusion, or sold onward to recyclers for pelletising. Typical traded regrinds include PP, HDPE, ABS, HIPS, PC and PVC. Compare forms in our scrap vs regrind vs granules guide.

Regrind should be stored dry and covered, since dust, moisture and stray material picked up in storage can spoil an otherwise clean lot.
