Hundreds, 400-700 I think, but I'm not certain, landfill sites do not provide good conditions for nonbiodegradable plastics to degrade,

A non Biodegradable plastic bag will decompose in 500 years


Biodegradable substances are waste substanses that can decompose after a peirod if time whether short or long e.g basically food, paper, etc While non biodegradable substances are waste products that can not decompose even after a long period of time e.g glass, metal cans, cups, plastic and the have to be recycled.


Different substances take different lengths of time to decompose


The most time it takes for biodegradable substances to disintegrate is 180 days.


No, plastic takes a very long time to decompose, and is not biodegradable. Some plastics are able to be recycled, but not all.


depends: biodegradable ones may go faster, i think plastic usually takes 15 years to decompose.............But, yes, if it is biodegradable, it will decompose faster...


Plastic takes 100 billion years to decompose. Even something as tiny as a plastic wrapper will not decompose for that long.


It takes forever it is non-biodegradable


"Plastic" is broad term that can be used to describe anything from bread dough to Teflon. Certain types of plastic are readily biodegradable, but can take a long period of time to decompose. Decomposable plastic used in plastic lunch bags and similar usually have a starch molecule worked into their matrix and are said to decompose in a composter in a few weeks, Impervious plastics like Teflon are impervious to microbial and chemical attacks and will last essentially forever.


You mean decompose -- Plastic decompose in a long period of time depending on the type of plastic and the environmental condition to which it is exposed.


Plastic is a non-biodegradable substance. Yes, it is long lasting.


Examples are plastics, metal and glass. Dangerous chemicals and toxins are also non-biodegradable, as are plastic grocery bags, Styrofoam (polystyrene), and other similar materials.


it takes 100 years to for it to decompose but a plastic one because plastic can not decompose so it can't


Non-biodegradable substances can last forever. Some substances are slow to degrade, but they still degrade over time. Those that are non-biodegradable should not degrade, even over long periods of time.


Polythene is a long chain of carbon compounds and these are non-biodegradable i.e, they don't decompose..........These substances undergo photo degradation in which they convert themselves into small toxic substances..........when this toxic substances are eaten by cattle they die..............


Plastic will take 75 to 405 years to fully decompose


The plastic bag will not decompose but it may clog up the toilet.


That will depend on the material and on the environmental conditions in which it is decomposing.


Non-biodegradable wastes take a long time or never to decompose. * metal cans * bottles * toxic chemicals * plastic products * metal scraps


Plastic is one of the very worst items to decompose. Plastic has a very bad effect on our ecoysystems


they take about 700 years to just begin to decompose and never fully decompose.


A plastic bottle takes 450 years to decompose.


It depends on the material. For example, tin cans take 100 years to decompose, styrofoam cups take 400-500 years and plastics take thousands of years to decompose. Plastics are the materials that has the longest decomposition period because they contain materials that do not decompose easily.


The amount of time that it takes for plastic wrap to decompose it dependent on its size and materials. However, on average it takes 500 years to decompose.


it takes thousands of years for a water bottle to decompose.
