how long does it take a plastic bottle to break down in a landfill?

it depends how emotionally stable it is, and if it has other plastic bottles for support.

Plastic is a polymer, meaning it is a chain of small similar units all connected in a single molecule.  Usually it is made by taking a solution that consists of the building block units (called monomers) and including whatever chemicals will make the monomers bonds together.  The mixture is put into a mold and heated, and the resultant polymer has huge, inter-tangled chain molecules that become rigid and hard.  The mold is removed, and voila.

22 hours 15 minutes\n\nSeems like this science fair project was done already.

Slightly over eight minutes.\n\nTo be exact look up on Internet\n\nBest Regards

every thing is biodegradable if you give it enough time from 2 weeks for some things to 1,100,000 years for others

ok, guys.  both v_dawg and quicksilver are right.  when water makes a phase transition from liquid to solid (freezing) it expands in volume; that's why bottles filled with liquid will crack in the freezer.\n\non the other hand, if you leave it sitting there for a while, there will be a slow phase transition from solid to gas (sublimation) and over weeks-months the ice cubes will noticeably shrink in size.

pvc pipe does not corode or oxydize. copper does. the salt in the system acelerates the rate of corotion. i think that the pvc would last longer anyways because plastic takes like 10000 years to break down. i dont know what bsk stands for(its probably obvious but im just not making the connection)

Check this link... Has good info...:\n\nhttp://en.wikipedia.org/wiki/Plastic

Check the yellow pages\nCall a junk yard\nCall a landfill\nSoft drink bottling plants have plastic ones that smell good!

I try, i recycle and try very hard not to waste water, but i always feel so guilty everytime i put another plastic milk bottle in the bin or a juice carton etc... it is scary to think how much packaging is used and thrown into the bin. I think we should be writing to retailers and asking them to reduce their packaging. I purchase products for the product inside, not the wrapping. I think in the future people may end up living like humans used to in the past with out electricity and cars. We should all do our bit, and get on the case of the people who make the decisions.  Great, thought provoking question.

It will be detectable for approximately 6 months after the last intake. As for the effects themselves, the direct ones should pass after a week. The more lasting effects (such as memory problems) caused by long-term usage should disappear within a couple of months.

you need a blow moulder,it is easily available in the market or search on the web you can get number of manufacturers.you can recycle it into ice trys or something like that and you also need a granuler. yes you can get a ready market because there is lot of want for recycled products and for medical field you can recycle your bottles into injections etc..

Items needed -\n\nPlastic Bottle\nDry Ice\n\nHow to do it..\n\nPut some dry ice in the bottom of a empty water bottle - little chunks of it should be fine. Put about an inch or two of it in the bottom, you dont need much at all\n\nNow here is the dangerous part..\n\nPut some cool or warm water in the bottle, just pour it in almost to the top, leave about an inch or two, now put the cap QUICK and throw it or put it on the ground, it could go off quick, or take a few minutes.\n\nIf will expand and expand until it goes off, so if you think nothign is happending, you are WRONG. Give it at least 5 minutes. If it has not gone off, throw rocks or somethin at it and then it should go off.

Polymers from some plastics can supposedly leach.\nThis happens e.g. if you microwave something without removing the saran wrap.\n\nIn general the environmental hazard with plastics and polystyrene is not that they're toxic, but that they will last for thousands of years. It's unfortunately more economical to make them disposable than to recycle. If oil hit $200 a barrel or there were higher pollution fines /landfill fees this would change.

A note on recyclability . . . \n\nFor food products in the US, recycled plastic must be depolymerized (broken down into component cheicals and no longer be a plastic), then repolymnerized to be used in food-safe applications. This is not the case if one uses recycled plastic to make fabric, or for use in non-foodsafe applications. The capital cost of the plant and energy involved in depolymerizing and repolymerizing the plastic make recycled plastic prohibitively expensive for foodsafe applications.

Well, you'd have to specify what you are trying to dissolve.  Many plastics are soluble in several solvents... N-Methylpyrrolidone being a good one.  Solvents generally do not attack metals, unless they contain water.  I would steer away from an acid or a base.  Can you say what you're thinking of?  If so, email me at connecticutpoet37@yahoo.com
