rPP PIR Pellets — Recycled Polypropylene for Compounding Applications
rPP PIR Pellets — Recycled Polypropylene for Compounding Applications

How post-industrial diaper waste is processed into rPP PIR pellets — and what GRS certification means for recycled content traceability.
Polypropylene (PP) is used across packaging, industrial, and compounding applications. In recycled polypropylene processing, feedstock source and processing conditions can influence the properties of the recovered material.
Regenport’s rPP PIR pellet is produced from post-industrial diaper manufacturing waste generated during production processes. The recovered PP material is reprocessed into mixed-color recycled polypropylene pellets for compounding and recycled plastic applications.

From Diaper Manufacturing Waste to rPP PIR Pellets
Post-industrial polypropylene waste generated during diaper manufacturing is collected and processed through mechanical recycling operations including shredding, melt processing, and extrusion.
The resulting recycled PP pellet is supplied for PP compounding, blended recycled plastic applications, and other polypropylene-based manufacturing processes.
Recycled PP Pellets for Compounding Applications
With an MFI of 48.6 g/10min and a density of 0.9 g/cm³, rPP PIR pellets may be evaluated for polypropylene compounding and recycled content formulations, depending on product specifications and processing conditions.
GRS certification documentation may be provided for customers requiring recycled content verification as part of material sourcing and supply chain documentation processes.
