Products - EVRgreen™ EPS


The First Biodegradable* EPS Resin

EVRgreen™ EPS anaerobically biodegrades an average of 45% in 562 days in conditions that represent biologically managed landfills of the Southeastern US*.

EVRgreen™ EPS degrades only in a microbe rich environment and the resin properties are not changed from standard EPS.

* Using the ASTM D5511-11 test method, cups made from EVRgreen™ EPS were found to degrade over 45% in the first 562 days of testing. The test conditions were >48% solids, which is representative of wetter landfills such as in the Southeastern United States.

EVRgreen™ Biodegradation Test

StyroChem® HFR Certification

EVRgreen™ EPS maintains the exceptional performance characteristics of molded EPS foam:

  • Superior Hot and Cold Insulation
  • Condensation Resistant
  • High Strength
  • Light Weight
  • Wide Performance Temperature Range ( -20oF to 190oF)
  • Shelf Life Stable
  • Recyclable with all Polystyrene

With two food contact formulations, EVRgreen™ EPS is well suited for manufacture of thin to medium wall packaging and container applications.

* Density potential is a function of utilities and expander capabilities; the above values represent optimum expansion conditions.

These products meet FDA 21 CFR, EU framework 1935/2004 and EU regulation 10/2011 requirements for direct food contact applications. This grade of EPS contains an additive that enables biodegradation under anaerobic conditions similar to those found in biologically active landfills*.

Recyclable where facilities exist.
