Read up on landfills. There's little or no effort to make them decompose. Impermeable soil layers are deposited to expressly prevent mixing and mulching, since that would allow contaminated water to travel from layer to layer.
Clearly some things in the landfill don't decompose, but like others have pointed out, they will someday become profitable to mine if they're full of so much concentrated stuff.
