Can bacteria help reduce solid waste? More specifically, can bacteria break-down plastics? Is this practical?

I am researching methods of solid waste management. In particular, I am exploring bioremediation technologies. I am curious to know why bacteria are not more comonly used to eliminate plastics from landfills.

Go to the Environmental Sciences (or equivalent) department of any University or College, and you will find students isolating specific bacteria to do thi very thing, amongst hundreds of other promising applications; bacteria are being 'trained' to eat plastics, diesel fuel, waxed paper, newspaper and polystyrene cups, among other things. The reason they are not more commonly used is probably a function of time economics. Once the fumes from burning trash begin to hinder the breathing of the grandchildren of government lawmakers, something might happen!
Reply:Most plastics are not biodegradeable. In a landfill there is not enough oxygen for decomposition to occur.
Reply:Plastics cannot biodrade so bacterica cannot decompose the substance. They breakdown organics.
