Best Answer

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.

How long does it take for a water bottle to breakdown?

It takes depends on the type of plastic, but no one is certain how long any type of plastic takes to break down. Many early plastic toys from the 60's are beginning to break down significantly. However, clear water bottles like Dasini and most other brands use PET. PET is a relatively modern plastic so there is little information on its degradation.
