From Yahoo Answers:
Every commercial gum has a gum base, just like every trophy has a trophy base, and in some cases the two are disturbingly similar. The base makes up a percentage of the gum; the remaining ingredients are flavor and sugar. Gum bases are the part that we chew and chew and chew long after the flavor is just a memory. They are grouped in categories: elastomers (including natural and synthetic rubbers), resins, plasticizers (such as waxes, vegetable oils, and glycerides), adjuvants (including calcium carbonate, talc, or other charging agents), and antioxidants. In other words, the gum is, at base, plastic or rubber or wax.It takes 1000 years for it too biodegrade and that is if it is buried. :)
5 to 10 years.
300 years
1o years
Eraser is made out of rubber. If exposed under the sun, an eraser will take between 50 to 80 years to biodegrade.
10 years
How long it takes for an aluminum can to biodegrade
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.
Electronics can take multiple years to decompose. Electronical waste is called e-waste. It can take up to 1,000,000's of years to biodegrade.
It can take anywhere from 2 weeks to 50 years for certain items in a landfill to biodegrade. Organic materials like food waste and paper break down much faster, while plastics and metals can take hundreds to thousands of years to degrade.
a long time.
No, not decomposed in nature. Clean burning though in waste ovens.
