PE/PP-rich streams

Rigid packaging, films, and PE/PP-rich mixed fractions.

Target output

PE-rich fraction · PP-rich fraction

PE and PP film offcuts, moulding sprues, trays, and regrind

Access constraints

  • Saturated C–C backbone
  • Mixed resin fractions
  • Contamination
Polyethylene and polypropylene constitutional repeat units resolved into PE-rich and PP-rich fractions, measured by yield, composition, and purity without assigning direct backbone-cleavage products.
