> PVC will break into VC No it will not, stop pushing junk science. Vinyl Chloride is a chlorinated double-bond. PVC is made by opening the double bond to form connected monomer units (i.e. polymers). PVC doesn't "degrade" back into a higher energy state compound. Even if you left it you in the sun where UV might re-double bond it, the molecule itself is incredibly reactive - it's environmental lifetime is basically zero under those conditions since it'll oxidize and break down in air in a few days at most, and photochemical reactions are amongst the slowest and most inefficient. Buried PVC doesn't even have the energy to do that.
