We still don't know how much time is required. Were still counting. We do know that it is well in excess of 50 years. 50 year old recognizable Hot Dogs and readable news papers have been unearthed from low tech. land fills so, steel cans will remain in our landfills for a long time.
a tin can usually takes about 50 years to to break down in a landfill
67,000,000 years!!!!!!!!!!!!!!!oh no
It takes 80-100 years
In a moist landfill a paper cup will biodegrade in 5 or 6 days. If it is coated with wax it will take several weeks.
It takes hundreds of years for tires to decompose. If they catch on fire, they'll break down faster, but will release toxins into the air.
50 YEARSto bio degrade u roxs by the way cuz u lookin at dis
Styrofoam cups last in the landfill for hundreds of years. Paper cups break down much faster. Paper would only last for a month.
It takes about 500 years for a plastic container to decompose in a landfill. It isn't until the chemical bonds between the atoms start to break down.
700 years to break down
it depends on the environment and it usually takes a long time too break down.
A cotton or woolen sock (natural fibres) will break down in a warm moist landfill in a matter of weeks. A sock made of man-made fibres (rayon, nylon etc) will really never break down. It may break into tiny pieces (which animals and insects may eat) but it will still remain rayon and nylon etc for ever. (It is possible that a chemical reaction, or radiation from the sun, may change its composition.)
it takes 20 years approximetly to break down.
