10,00 years. no jokes!
Plastic doesn't decompose, unless it's made of vegetable oil. Normal plastic breaks down eventually into tiny pieces, but they're still tiny pieces of plastic, which kill birds and animals that eat them accidentally.
An average time for a plastic bottle to biodegrade fully is approximately 4-5 mins. However, there are many different kinds of plastic in the world, most commonly the hard and reusable ones, which take a longer time, and the soft and non-reusable ones, which take a shorter time. Time also varies with the size of the bottle.
Depends on the plastic.
A polyethylene or polypropylene bag is good pretty much forever if kept away from strong sunlight (e.i. buried in a landfill). Exposed to sunlight's UV it slowly becomes brittle and flakes away.
Bags with a degradable component like cornstarch or cellulose degrade under biological attack and other factors.
Hard plastic takes centuries to decompose. This is why there is a push among environmentalists to reuse and recycle not only plastics but any material that can be kept out of landfills.
About 400 years. Long time, huh?
100-200 years
3 years
how long does fabrics take to decompose how long does fabrics take to decompose
As LEGO bricks are made of plastic, it would take a long time. A long time would be hundreds of years or maybe even more.
It can take up to two months for an apple core to decompose in a landfill. Banana peels will take a few days to decompose. While glass takes a very long time to decompose, a paper bag can take up to five months.
It takes 100 years for a battery to decompose.
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.
No oxegen.
about 5oo years...
The plastic bag will not decompose but it may clog up the toilet.
Plastic bags, despite critical claims by ecological groups, do decompose. Originally the polyethylene in plastic grocery and garbage bags took a very long time to decompose (as other plastic items still do). However, the addition of various substances to the bags now causes the material to fragment, and it is then slowly broken down by natural processes. Early additives required sunlight (UV), but heat and moisture are now key to the degrading process.

It acually takes a really long time.. but a lot longer in a landfill.. people should just RECYCLE!!!!
