Why is landfill a favored method of waste in US?

Answer 1

Cost.

The US has disused quarries and little environment regulations making landfill cheaper.

In Europe the high cost associated with environment regulations and few suitable places are making other methods more economical

Answer 2

Beacause it the least expensive way to dispose of our waste.

The U.S. has much waste land space available, when compared to Japan and many other countries.

Answer 3

Primarily because we have decided it better to isolate waste from the environment rather than release it back in a manner that dilutes the waste to make it safe.  A landfill is constructed to contain the waste buried in impervious clay layers.  Any seepage of fliud is captued and treated.  The alternate would be dumping  on the roadside or at sea or example.  The idea being that the waste would take a long time for the waste to disperse back into the environment.
