I had some conversations with some folks who worked in asbestos removal. In the US, everyone who touches the stuff owns it forever. The bags used to pack it have the name, license #s and contact info for the company removing it. If the landfill decides 20 years from now that they no longer want it in their landfill, your company gets to pay to remove it and then dispose of it in a new landfill.

The general feeling was that every asbestos removal company goes out of business (dissolve, chapter 7) in order to escape the permanent liability of the stuff. At which point it now becomes a SuperFund issue.
