How long do non-biodegradable waste substances last?

Answer 1

It should be noted that conventional plastics can be made biodegradable with the inclusion of a small amount of an additive that promotes biodegradation. It is then called oxo-biodegradable plastic. Read more at http://biogreenproducts.com . Many plastic disposable products are being introduced that can be biodegraded using oxo-biodegradable technology.

Answer 2

From 2 Weeks To 5 Years.
Plastic does NOT biodegrade, because it is not make of organic matter. It simple breaks into smaller and smaller pieces of plastic until, after who knows how long, it is finally broken down to it's molecular level. The molecules eventually break down into atoms, and the plastic no longer is plastic. Look in any scientific book about plastic, and you will find this information...........

Answer 4

A non Biodegradable plastic bag will decompose in 500 years

Hundreds, 400-700 I think, but I'm not certain, landfill sites do not provide good conditions for nonbiodegradable plastics to degrade,
