a long time.
All i know is that airsoft pellets are made of plastic. Therefore, it would take a very, very, very long time to biodegrade, just like any other solid plastic product. Hope this helped :)
This depends on many other factors.
paper does not regenerate
You shouldn't prefer anything to the reusable bags you bring in or buy at the store (so you can bring them in next time).Plastic bags clog things up, get eaten by sea turtles etc.Paper bags take up more space in landfills, don't biodegrade nearly as fast as people think they do, require more fuel to haul, and divert paper from better uses.
Depends on which metal. Also, it depends on what you mean by degrade. The metal molecules will never disappear, they will just disperse or get incorporated into molecules. But in general, a LONG TIME.
Yes, they are made of organic materials that will biodegrade over time.
No-one really knows, but estimates suggest 500 to 1000 years.
a long time
A disc's lifetime is measured by the number of years for which the medium can store the data successfully in it. A typical cd exists for around 217 years - so that would be its lifetime.
the time is how much time i take to take a shower
It depends on what it is. Paper generally takes about 2 years and cardboard a little longer. It can be shorter if they are properly composted. However, a mouldy piece of lettuce for example, would biologically degrade and take a much shorter period of time. Some plastics will take many thousands of years.
