No, not decomposed in nature. Clean burning though in waste ovens.
It Takes 20,000 years.
It takes 1000 years for it too biodegrade and that is if it is buried. :)
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
Polystyrene is today difficult to be recycled.
Polystyrene is formed from only one monomer - styrene.
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
How long it takes for an aluminum can to biodegrade

a long time.
Eraser is made out of rubber. If exposed under the sun, an eraser will take between 50 to 80 years to biodegrade.
5 to 10 years.
1o years
how long does a crisp packet to biodegrade
10 years
From www.mongabay.com: Plates made from organically grown, highly sustainable bamboo will biodegrade in four to six months, the manufacturer says.
A cotton bag will take a few months to biodegrade/decompose.
300 years
It can take tin cans anywhere from 50 to 100-years to biodegrade. The decomposition is very dependent on the environment where the material is decomposing.
