A graph showing how long styrofoam biodegrades?

Answer 1

Exposure to UV from sunlight will degrade the styrene molecule. Exposure to ambient ozone will also degrade the styrene molecule. In the sun, in a place with lots of ozone pollution, styrofoam falls apart in months. Built into refrigerators and ice chests, sealed away from ozone exposure with antioxidants built in, styrofoam will last for (probably) centuries. In a landfill, styrofoam usually lasts about a decade, depending on moisture and biological history.

Answer 2

Styrofoam does not really biodegrade. Therefore, any graph showing this process would either have to be very, very long, or would not be correct.

Answer 3

Styrofoam does not decompose easily. It's almost permanent.

But in fact, it takes 500 years! So please use alternatives if you can avoid them!

Answer 4

In a clean dry place out if the sun, never!
