The EPS production poses no threat to the
ozone layer, pentane, the blowing agent used in EPS contains
no ozone-depleting substances and the amount released during
manufacture is only about 0.2 percent of the total man-made
emissions of volatile organic compounds (VOC's). It actually
is a naturally occurring chemical like methane. It is also continually
being formed by natural processes; for example in the digestive
tracts of animals and by the anaerobic decomposition of plant
matter. |

Polystyrene
also has a low stability and under the influence of humidity
and atmospheric radiation (especially UV light) it is quickly
converted into carbon dioxide and water. Because of its low
stability, pentane cannot reach the higher (stratospheric) atmospheric
levels and therefore does not contribute to ozone depletion
(unlike chlorinated blowing agents such as CFC's and HCFC's).
Additionally pentane does not contribute directly to the "greenhouse"
effect.
