how long do plastic bags take to degrade
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, some more conservative are 1000 years.The bags will photodegrade, but that will take a long time, hence the 500-1000 year estimate.f you are planning to kill yourself by putting a plastic bag over your head, there are probably other questions that you should be asking, rather than how long it takes to di â¦ e with a plastic bag over your head.
