How long does plastic take to break down?
A very long time. Exactly how long depends a lot on the specific type of plastic as well as the environment that it is in. Exposure to direct sunlight helps speed up the process. Plastics never actually 'decompose', they merely break down into smaller and smaller pieces. Being an inorganic material, in never will compost.

Answer . The water will not ever break down. You will need to remove it.
Plastic doesn't decompose, unless it's made of vegetable oil.Normal plastic breaks down eventually into tiny pieces, but they'restill tiny pieces of plastic, which kill birds and animals that eatthem accidentally.
Plastic will degrade at a varying rate depending on its quality. From days, to years. Now, by degrade we mean it will break apart into smaller pieces of plastic, right down to single molecules. However, if you're meaning break down into different substances which could possibly be of use in natur…e (such as living things do) then the answer is never. Every molecule of plastic we have made which we haven't manually changed to a different form is still in nature. This fact is actually a very critical environmental concern currently, as there is a massive amount of these single molecules of plastic in the oceans which are effecting fish populations (and things which eat fish, like us). A: The degradation and decomposition for plastic is dependant on the type of plastic and the exposure it has to sunlight, water, heat, chemicals and other factors. Some plastics contain starch molecules which decompose under the influence of bacterial action. Most plastics decompose when exposed to heat and the ultraviolet component of sunlight. Inert plastics in landfills where they are dry, not exposed to sunlight and not mechanically abraded can last for hundreds of years, but under these same conditions a steak willl last for about the same amount of time. A: The answer to " How long does it take for plastic to degrade?" is NEVER. It breaks down into molecules. Molecules that are harmful to the environment. Humans made them and humans have to UNMAKE them. They must be broken down into some form that nature can ingest without dying. The amount of NON-BIODEGRADABLE plastic in our oceans is becoming cataclysmic. Plastic of varying sizes is killing large to very small fish. There are so many MILLIONS of TONS of plastic in the Pacific ocean that plastic sand is now washing up on the shores of California. There is a plastic dump the size of Texas in the middle of the Pacific that WILL NOT GO AWAY until we MAKE IT GO AWAY and in the meantime it is killing fish all along the food chain. The amazing thing about non-biodegradable plastic is that the same piece of plastic can kill generations of fish or birds. The fish or birds eat it, DIE, then the dead fish or birds biodegrade and the plastic that killed them, good as new, floats back into the ocean to kill more fish and birds. Over time this equates to an exponential number of deaths in marine life. So, if we stopped dumping plastic into the ocean right now, the plastic already there would continue killing marine life for hundreds of years. (MORE)
Because Plastic bags have only been around for 50 years, scientists use respirometry tests. First the scientists take something like a banana peel, a newspaper or a plastic bag (waste products) in a vessel along with compost that is rich in microorganisms, and then they expose the mixture to air or… oxygen. The microorganisms consume the waste sample and make carbon dioxide or CO2 and the amount of CO2 shows the degradation of the waste samples. Newspapers take 5 months to biodegrade and bananas take just several days. When scientists tested plastic bags using the respirometry test no CO2 was produced and there was no decomposition. This is because the majority of plastic bags are made from polyethylene. Microorganisms don't see it as food because it is man made. 500years to 1000years they might take a couple of years if you put one in a microwave, so far no tests have been accurate because the motor of the microwaves blew up.

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.
a tin can usually takes about 50 years to to break down in a landfill
Plastic never biodegrades, it takes forever. If it seems to start biodegrading, its just getting smaller from weather
The amount of time it takes for a plastic bottle to break downdepends purely on the bottle. Some bottles are made of moreresistant plastic material.
Plastics in general are not considered biodegradable due to their molecular stability. Plastics do not easily break down into simpler components. A plastic bag will break down into smaller pieces of plastic, but that is not the same as biodegrading. Some estimates are 500 years to degrade, som…e more conservative are 1000 years. The bags will photodegrade, but that will take a long time, hence the 500-1000 year estimate. The problem is there are no bacteria breaking down the plastic. Eventually some may evolve to do so, but science may need to step in and speed the process along. (MORE)
80 to 200 years. This is the answer that you see in many texts. However, I am an avid scuba diver. And I know by experience that when I find aluminum cans in the Caribbean, if they look like they have been in the water for awhile, when you touch them they fall appart (as if they are made of tissue… paper). The can tops seem to be a bit more solid, but still seem much more flimsy. Aluminum cans have been used since the 1950's...so there is something very wrong with this 200-500 year number when salt water is concerned. I have been told that water temperature also is a big factor (the warmer the water the quicker aluminum will break down) BUT...It really is a molecule on a gnat on a fly on an elephant's ass when you think about it. In the human mindset, 200 years is a long time. Heck, so is 50, or 20. 20 minutes is a long time for me if I'm running on a treadmill. But to an astronomical body that is 4.3 BILLION years old, 200 years is hardly a mouse fart. Also, considering that it has 70% of its surface covered in a corrosive substance, throwing one, ten, or a million aluminum cans (which came from the earth, and there is plenty of aluminum in the seabed and even the seawater) is probably not going to make a difference. All of that said, I could never see myself intentionally throwing garbage overboard for the same reason that I would bend over and pick up a piece of trash and throw it away if I were in a public place, like a shopping mall. I just am not of that mindset that let's garbage go where it may. (MORE)

It takes the liver 1 hour to metabolize one ounce of ethanol. Answer Not quite. The body can metabolize one standard drink--which is 0.45 ounce of alcohol--in an hour.
it depends on the type of plastic. a bottle stays forever, yet polyesterine the main material biodegrades very quickly in sunlight
I don't know about a whole pack of cigarettes but it takes five years for one cigarette to break down naturally. So i guess you could times that by the amount of cigarettes in the pack.
Plastic is very strong. Although it had one weakness, Heat plastictakes 36 minute melting in a commercial oven on 200degrees Celsius.
It very depends on what type of plastic. Normally it taks hundreds to thousands years.and somtimes forever.
Once a pen is used and tossed into landfill, it could take up to 50,000 years to decompose, which is staggering considering over 14 million pens are bought worldwide, each day. :(
hundreds, glass takes thousands!!. but glass is just fused sand and can be returned to its natural form by simple crushing. plastics are complex hydrocarbon polymers.
It depends. Its a few days at least. We use bacteria at our sewage treatment plant to eat the sludge. Sludege is what you are saying, right? All of the raw sewage goes though filters then the sledge that collects is eaten up by living bacteria. If your talking about the RidX for septic tanks it will… take a few days to multiply and eat sludge in the botton of the tank. (MORE)
It depends upon the type of compostable materials , and upon the meeting of certain compost pile requirements . For example, the best compostable materials are kitchen scraps other than dairy, greasey and oily, and meat products; and yard wastes such as grass clippings. For such compostable ma…terials fit easily into the brown, carbon-rich and the green, nitrogen-rich categories.. Additionally, certain levels of air, moisture, and temperature must be met. For decomposition without adequate air becomes anaerobic. Such a breakdown in the absence of oxygen produces methane, which is a greenhouse gas. Also, the pile mustn't be waterlogged. Instead, it must have the consistency of a gently wrung out sponge. And the pile must be turned regularly. The more the pile is turned, the faster does composting turn compostable materials into compost. In fact, under the previously described conditions, it's possible to have compost in anywhere from less to a month to less than a year . (MORE)
It depends . Proper levels of air, moisture, and temperature need to be respected in the compost bin, box or pile. There must be enough air so that decomposition takes place aerobically, with oxygen. Without enough air, and in the absence of oxygen, the breakdown takes place anaerobically, as in lan…dfills. And anaerobic breakdown is accompanied by foul smells, and the production of methane, which is a greenhouse gas. There must be just the amount of moisture that leaves compostable materials with the consistency of a gently wrung out sponge. The temperatures must be enough to keep the materials heated, consistently and equally throughout. And the materials must be turned regularly. The more often the materials are turned, the quicker the decomposition takes place. If the preceding conditions are met and kept up, then compostable materials break down into dark brown, fresh-smelling, organic matter-rich humus in anywhere from just under a month to just under a year .

What do you mean? Do you mean " how long does it take an adult to completely break down (metabolize) a single drink?"
\nIf you leave a plastic shopping bag in the garage in relatively dry conditions it will not last more than 3-4 years. By then when you pick it up it will disintegrate. If it is wet in the ocean? Not sure
Most plastics break down more quickly when exposed to sunlight than when buried. The exact time will depend on the type of thickness of the plastic. Some plastics are being made now that breakdown in about 6 months, others may take 10 years or more.
This is one of the strong arguments against using a lot of plastic: It doesn't .. Fifty thousand years from now, when aliens from a distant galaxy land on the dry dusty earth and dig through the gray sand to find out whether there was ever life here, they'll find buried plastic.. And BTW ... th…e word is " disintegrate ". (MORE)
The time can range from minutes to years depending on the environmental conditions and the type of material. Environment conditions may include temperature, humidity, pressure, type of organisms available to degrade the product, including bacterial, and sunlight Some materials degrade slowly or not …at all or may be gone in weeks. A good example is an animal body. If mummified in a dry local it will last for centuries. In shallow warm ocean water it will be mostly gone in days. (MORE)
It depends on whether you are a fatty or thin guy. Alcohol absorption takes little longer with fatty guys. For a thin guy, it takes hardly a few minutes to start the metabolism. For them, alcohol effects take place within 5-10 minutes.
most plastics break down faster in the presence of sunlight with the exception of some UV resistant plastics if you left it in the sun i would venture to guess that it would last about 7 years but if it was burred(in a the dirt) i would guess well over 100 years but if it was in a land fill i think …that some of the acids and chemicals created by the decay of organic materials (ex banana peals and the like) i think it may speed the proses i think but it raises the questions that after it is broken down is the chemicals that make up the plastic still there.... a fun story i once seen a plastic 5 gallon pail ant it was half under ground and half in the sun after about 3 years the in the sun part was very brittle ad crumbly you could crush it wit your figures but the burred part was still in new condition. i hope this helps but i am not a professional in plastics i base this on observation (MORE)

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.
The time for any kind of surgery depends on the situation and on what is being done
A range of about a month to about a year may be the amount of time that's needed to break down food in a compost pile. The rate of the breakdown depends upon four sets of factors. One is the size of the pile. Larger piles tend to take longer to break down than smaller. Second is the compostabil…ity of the food. For example, dairy products, greasy or oily foods, and meats aren't good candidates for composting. Among other things, they'll bring in foraging area wildlife. Third is the following of proper procedure. Proper composting requires appropriate levels of air, heat and moisture . For example, the consistency of the compostable materials must be kept at that of a wrung out sponge. Fourth is the number of times that the compostable materials are turned within the pile. The more the materials are turned, the faster they break down. (MORE)

Depending on the conditions for decomposition, it varies. It may take up to 80 years. You can read more about decomposition of many household items, including cans, below.
Depending on the environment... up to two years. Especially in cold environments such as ski resorts.
Your liver is the main place in your body where alcohol is broken down . ... The average person will take about an hour to process 10 grams of alcohol
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.
degradable plastics will thinner, lighter, reduction in strength, become scraps after 3 months in normal environment. It has to be explosed in air to degrade.
It depends on the conditions. If you were hoping for a definite answer like "20 years" or something, sorry. Ester linkages do hydrolyze in mildly acidic conditions, which can be reasonably expected in a landfill, so polyesters will, eventually, break down. How quickly depends on how acidic it is an…d exactly what form the polyester is in. In the form of small fibers... say, a shirt... it will degrade rather more quickly than if in the form of solid pieces like a soda bottle. (MORE)
It can be used right away. I have goats and it works great! Other manure like chickens, cows and horses burn the root system. It doesn't need to break down. But if you want it to it takes a few years unless you crush it up :)

An ordinary steel paper clip will crumble into rust within a year or so, depending on the moisture content of the soil. They are seldom given any real corrosion protection, because they are designed to hold dry things together.
