Why Recycling Expanded Polyethylene and Expanded Polypropylene is Good for Sustainability and Profitability

Posted by Chad Plotts

The demand for sustainable materials, including expanded foam plastics, is pretty evident these days. When recycling foam materials like expanded polyethylene and polypropylene, economical transportation is often a major issue that can make or break a recycling program.

 

Expanded polyethylene (EPE) and expanded polypropylene (EPP) have become sources for a variety of packaging and energy absorption needs. In most cases, these materials are fully recyclable and even more valuable as recycled 

commodities. The values for recycled polyethylene and polypropylene recycling codes continue to climb as more and more avenues for these recycled materials are becoming apparent.  Environmental debates over plastic materials have driven up the demand to divert these foam materials from landfills. Yet all too often, these fine materials that are in high demand in the marketplace are sent to landfills as waste.

How Much Scrap Foam Do I Have?

Posted by Phil Plotts

One of the problems many people have when considering a foam scrap compactor or densifier is how much waste they have. Foam packaging blocks and colored styrofoam sheets are very lightweight and can be very bulky. With these materials, what appears to be an immense quantity isn't a substantial amount at all. Typical polystyrene foam packaging and insulation is usually in the density range of 1 to 2 pounds per cubic foot.  What this means is if you have a 12-inch x 12-inch x 12-inch cube of solid foam, it would weigh between 1 and 2 pounds. Since most packaging foam is not used in a solid block form but is molded into relatively thin designs to protect products, several cubic feet of polystyrene or polyethylene packaging foam may be required to equal a pound of foam.
