There is so much trash in New Orleans and the Gulf Coast. What will the survivors and residents do with all of the flooded cars, furnature, houses, and junk?
Most of the debris from the houses (furniture, wood, etc) will wind up being landfilled. They have all of the major hauling companies involved in the cleanup efforts. Where it is economical they will recycle as much as possible. Most of the metals and recoverable/reusable things will get handled that way because they have value to all the people involved.
Hope this helps!
