A Styrofoam Cup


Sometimes I write of other things than just my books. A few years ago I was in a creative writing class and the assignment was to write one page about a commonly used product. I had just been drinking a cup of coffee from a foam cup, so that is where I went with my assignment--right to that cup. While it may be boring to some, others may find it very informative, just as I did.
 
A Styrofoam Cup

Ah, here I am with an assignment to write about the old Styrofoam cup. Alas, there is no such thing. I bet many of you didn’t know that. Yes, it’s true. Styrofoam is a trademark of Dow Chemical Company, and according to Dow, you can’t drink from a Styrofoam cup. Styrofoam is used for insulation and floral foam, not for disposable food packaging, such as drinking cups.

A Styrofoam cup is actually made from a form of foamed polystyrene.       But that doesn’t keep it from being an excellent product. The cup has very good insulating abilities. Polystyrene is made of 95 percent air and only about 5 percent polystyrene molecules, according to the Polystyrene Packaging Council. It’s that 95 percent of the cup that does most of the insulating. Using more foam increases the distance through which thermal energy encounters the resistance of insulation and thus decreases the rate the energy can escape. The thickness of a Styrofoam cup will affect its ability to keep its contents hot or cold.

STYROFOAM Brand Foam is not used in the manufacture of disposable foam products, such as food packaging, cups, plates, coolers or egg trays. These disposable products are made of either molded expanded polystyrene beads or thin extruded polystyrene sheet, neither of which is manufactured by Dow in the United States.
Styrofoam, or more accurately, polystyrene cups are a better deal for the environment and has better biodegradability abilities than paper cups. Since 95% of the content is air, the cup will condense to 1/20th its size in short order when compressed by the garbage on top of it in the landfill. In fact, less than one percent by weight of the total municipal solid waste disposed is polystyrene.  Paper cups on the other hand, are made from trees that must be harvested, which hurts the environment, and because of the laws that govern landfills today, paper cups may never completely disappear due to biodegradability. Very little of the waste discarded in today's modern, highly engineered landfills biodegrades. Because degradation of materials creates potentially harmful liquid and gaseous by-products that could contaminate groundwater and air, today's landfills are designed to minimize contact with air and water required for degradation, thereby practically eliminating the degradation of waste.

Polystyrene cups get the job done. They are:

* Versatile, practical, and convenient to use
* Maintain beverages at their optimal temperature longer
* Insulated foam keeps your hands comfortable
*
Ideal for hot and cold drinks
* Coffee, tea, cappuccino, hot chocolate, hot cider, juice, and soft drinks
* Sanitary, sturdy, efficient, economical and convenient

 So next time you get a cup of java to go, remember, you can't drink coffee from a STYROFOAM cup - because there is no such thing!
