Styrofoam, formally known as expanded polystyrene (EPS) is a common household material that has been in existence for decades. It is another type of plastic that is expanded with air to form a foam that is ideal for use as item packaging and insulating beverages in the form of a cup. Due to these properties, we humans use a lot of it. According to the Environmental Protection Agency, Styrofoam is the fifth largest source of hazardous waste in the United States.
Styrofoam, due to it being mostly comprised of air, floats on water and only breaks down into smaller and smaller pieces that can be ingested by wildlife, which can lead to choking and eventually starvation. It can also be easily carried by the wind, spreading this pollutant far and wide. Unfortunately, Styrofoam is not recyclable due to its lightweight nature, high economic cost of transporting, and the aftermarket process of degreasing, even though many Styrofoam products brand the recycling symbol.
Styrofoam is banned from all City-sponsored events as a result of these environmental dangers and any vendors who attend City events are also not allowed to not sell, use, dispense, give away, provide food in, or offer the use of Styrofoam at any and all city locations and facilities.
As with other plastics, the best way to reduce Styrofoam pollution is to just not use it in the first place.
