Polypropylene is widely used in industrial manufacturing, but feedstock quality, processing consistency, and traceability vary significantly between suppliers.

Regenport's rPP PIR pellet is reclaimed from post-industrial diaper manufacturing waste — a controlled, traceable feedstock that produces a mixed-color pellet with consistent physical properties suited for compounding applications.

Material Data

From diaper to rPP PIR pellet: how the feedstock loop works

Post-industrial diaper waste is collected directly from manufacturing lines before consumer use, making it one of the more consistent PP waste streams for PIR processing. This feedstock minimizes contamination risk and supports batch-to-batch uniformity.

The result is a mixed-color PIR pellet suited for compounding processes where melt flow consistency and density stability are key requirements.

Where rPP PIR fits in your compounding line

With an MFI of 48.6 g/10min and a density of 0.9 g/cm³, rPP PIR is compatible with standard PP compounding workflows. For formulators building recycled content blends, material properties and test data are available in the technical datasheet.

GRS certification means recycled content claims are independently audited — a requirement across an increasing number of European and global supply chains. For procurement teams adding PIR content to their supply mix, rPP PIR is a practical starting point.
