Copper does not rust. It will, on contact with the air, form a greenish "verdigris" of copper sulphate on it's surface - but that is not rust.
OOps - that should be copper carbonate. Copper sulphate is highly soluble and would not produce a patina. Maybe some copper oxide as well.
Technically copper never decomposes by nature/environment (in respect to earth's current surface environment),,, copper is producted as a biproduct in nature or by human beings and only accummulates,,,, it can be recycled or altered to a different states by high temperature or exposure to chemicals........ In respect to copper, exposed to normal ranges of our current environment will not decompose....... glass may take millions of years to decompose in our current natural environment.... copper will not decompose....
Technically steel or any other metal does not decompose. If you are referring to corrosion, it will eventually turn into Iron Oxide (rust) over time, but that is largely dependent on atmospheric conditions. The more humidity, the quicker. Less oxygen, slower. In the ocean with the salt water, VERY fast. The Titanic at the bottom of ocean cannot be raised due to this. The Titanic is no longer made of steel, but almost entirely of pure rust.
The company I work for built half inch thick horses formed from corten (a high quality grade of steel). These figures are expected to still be standing over Vantage, Washington (on I-90) 50,000 years from now.
On the other hand, a thin sheet of regular (non stainless) steel agitated in vinegar can entirely rust away within a couple of days.
IT CAN TAKE A REALY LONG TIME FOR MEATAL TO DECOMPOES(15-18 YEARS)
Acutally, the above is wrong.
No, metals rust. However, rust can be considered metal decomposition (kind of).

It depends on the type, location, and size of the plant.
Copper is an element. It is not manufactured.
it takes over a year for it to decompose
well, it depends on what type of metal.
Copper is an element; it doesn't "form".
7 years
It depends on what the toothbrush is made of.
The amount of time it takes for a paperclip to decompose depends on the material it is made out of. Metal paperclips take longer to decompose than plastic ones.

Steel pipe is made by pulling the molten steel through a cone before its welded together. Twenty one feet is the length at which the newly formed steel would hold a straight seam wield but still be able to be formed into pipes.
The vast, vast, vast, majority of 1944 pennies are copper. If it sticks to a magnet it /might/ be steel, though you'd have to take it to an expert to make sure it wasn't altered from a steel 1943 penny.
