How Nano-Purification Could Solve the Food-Grade PCR Problem

October 31, 2025

One company has figured out how to get virgin-quality PCR without contamination or water waste.

Pyrowave developed a nano-purification process that filters contaminated plastic at the molecular level using ceramic membranes. Like ultra-precise sieves, it removes heavy metals, inks, and adhesives. The output is food-grade quality that can be recycled infinitely.

We knew how critical this is for packaging and sustainability professionals especially with PPWR changing the way packaging is designed, sourced, and evaluated across Europe. So, we hosted a webinar that brought these questions to the table:

  • How can teams source PCR that’s genuinely food-grade and reliable?
  • What design swaps, inks, adhesives, closures can actually lift you from Grade C to B?
  • Reuse vs. deposit return systems: when to use each?
  • Data to capture now for PPWR reviews

We even shared a supplier diligence checklist and a component-swap matrix- simple, practical tools to help packaging teams make confident, compliant decisions.
