Styrofoam coolers are lightweight, cheap, and pretty good at keeping beverages cold.
They’re also pretty bad for the environment.
Styrofoam is Dow Chemical’s trademarked name for extruded polystyrene, and in addition to being conveniently disposable, it’s also a source of greenhouse gases, doesn’t degrade for centuries, and is highly flammable. Oh, and animals confuse it for food and could eat enough of it and die.
Igloo’s come up with a less destructive alternative made out of paraffin wax and recycled paper called RECOOL. The 16-quart cooler has a weight capacity of 75 pounds and is highly water resistant. Igloo says the RECOOL can keep ice cold for up to 12 hours and hold water for up to five days without leaking.
