StyroChem®, a leading global manufacturer of expandable polystyrene (EPS) has announced the introduction of their newly developed EVRgreen™ product line. It is the first EPS resin with EcoPure® technology. "EVRgreen™ is an exciting new environmentally minded product. Glenn Wredenhagen, President of StyroChem®, "This breakthrough promotes the biodegradation of the many foam products we use in our everyday lives. Foam has always been recyclable in the few communities with facilities, but now we have an exciting new breakthrough that productively completes the life cycle of foam. Consumers can now rediscover and get excited about foam." The majority of discarded plastics end up in biologically active landfills. Microorganisms found in these landfills are the key to the biodegradation of EVRgreen™ expandable polystyrene resin. These microorganisms interact with the resin's chemistry to break down the polystyrene at the molecular level.
"Our new EVRgreen™ resin will enhance a variety of end?use products across various industries which include protective packaging for consumer products, containers for foodservice and diverse custom applications." EVRgreen™ has been shown to biodegrade an average of 14.2% in the first 133 days of testing under conditions that simulate a biologically active landfill*, using the ASTM D5511?11 test**. The resin has been shown to promote biodegradation while still preserving the superior performance characteristics of traditional EPS resin.
*Present tests at 49% solids content approach the conditions of wetter landfills, such as in the Southeastern U.S. Biodegradation rates may be lower in landfills in other areas of the U.S. depending on moisture level in those landfills.
**ASTM D5511?11 specifies: This test method also may resemble some conditions in biologically active landfills where the gas generated is recovered and biogas production is actively promoted.
