EPS Densifier vs. EPS compactor

Posted by Phil Plotts

Densifiers vs. Compactors, what's the difference in the name.  In my opinion, it is just semantics!  Most of the sellers of EPS melting machines refer to their equipment as densifiers or thermal densifiers.  It seems many of the manufactures of EPS cold compression systems with screw augers use the term compactors and the sellers of hydraulically driven systems use both densifier or compactor.  In the end, all three types of systems, screw, hydraulic and thermal reduce the light weight foam material into dense logs, bricks or patties.  All three types of equipment densify and compress so a densifier is a compactor and vise versa.

EPS and Styrofoam is recyclable

Posted by Phil Plotts

There is an excellent article posted today on the Plastics Today website pointing out two important facts, EPS packaging is recyclable and EPS packaging is a small component in our landfills and solid waste stream.

2010 EPS Recycling Report

Posted by Phil Plotts

The latest EPS recycling report was just released by the Alliance of Foam Packaging Recyclers (AFPR).  The 2010 report shows a considerable increase in the EPS recycling percentage over the 2008 report, even during a poor economy when less EPS was sold.

How much scrap foam do I have?

Posted by Phil Plotts

One of the problems many people have when considering a compactor or densifier for scrap foam plastics is how much foam do they really have?  Since packaging foam is very lightweight and can be very bulky, what appears to be a large quantity may not be so much after all.  Typical polystyrene foam packaging and insulation is usually in the density range of 1 to 2 pound 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 the product, several cubic feet of polystyrene or polyethylene packaging foam may be required to equal a pound of foam.

Here are a few guidelines for estimating the weight of uncompressed EPS or EPE foam pieces.  (This excludes stacked sheet foam and block foam)

Recycled polystyrene, polyethylene, & polypropylene foam prices climb

Posted by Phil Plotts

Prices for virgin polystyrene, polyethylene and polypropylene resins in North American continue to increase.  Prices have increased as much as 20% or more since the beginning of 2010.  There has also been an increase in products made with recycled PE and PP content. These factors are helping to push up the prices for recycled PP and PE foam logs to very attractive levels.  At the recent Plastic Recycling Conference in Austin, TX, we received as many requests from buyers looking for material sources as we did for recycling machinery.  It is a good time to take a new look at your EPS, PE and PP foam wastes.  The return on investment for a foam compactor may be significantly better than a year ago.  We would be happy to assist you in your analysis and put you in touch with material buyers for updated material bids.

Plastics Recycling Conference 2010

Posted by Phil Plotts

I want to let everyone know that we are exhibiting again this year at the Plastics Recycling Conference 2010 which will be held in Austin TX.  The conference will take place on March 2nd and 3rd.  The conference will include a tradeshow.  We will have booth #304 and would love to have you stop in.  The conference sponsors expect a great turnout again this year.  There were a record number of exhibitors this year and all spaces have sold out.  This primary focus of this conference is recycling, not solid waste management.  This is one of the best conferences in North America to meet people interested in recycling plastics of all types.

What Is Styrofoam?

Posted by Phil Plotts

Many of us use the term Styrofoam as a reference to most plastic foam packaging.  We include foam drinking cups, packaging peanuts and the white material that our appliances, toys and so many other items are packaged in.  In fact, most of this is not Styrofoam.  Styrofoam is a registered trademark of Dow Chemical for an extruded polystyrene foam material sometimes referred to as XPS.  This material is always made in a sheet form and is generally the color blue.  The primary use for Styrofoam is for building insulation although you may find it used in Geofoam applications or in block form in the hobby store.  As Dow states on their website, " You can't drink coffee from a STYROFOAM cup. (There's no such thing.)"
