When I crossed the finish line of my first marathon back in 2011, I was handed a thin, light foil blanket. A runner’s body temperature begins to drop rapidly after stopping, and this was to retain some body heat until things stabilized.
It was over eighty degrees and sunny that day, so there was no danger of hypothermia. Still, I took the blanket as a first-marathon souvenir. But last month’s local marathon was wet and chilly, so the runners appreciated them, although they created a disposal issue.
The blankets are made of Mylar, plastic vapor-coated with aluminum. Both materials are recyclable by themselves, but together they are not. And when people started discarding them en masse, the volume quickly overloaded the receptacle. The Zero Waste team decided to collect them in the chance we could keep them out of the landfill.
We ended up with several large bags stuffed with Mylar blankets. What could be done? After some research we identified one bad option, one good (but costly) option, and one that didn’t help for this year but might for future events. Which one did we choose? Read on to find out!
