Interstate Trash

Yesterday I drove to a rest stop just before exit 35 on I-90 East. I was picking up a friend to bring him back to school, but It got me thinking about what rest stops do with their trash. Turns out, the answer is not too complex. Behind the rest stop, where the trucks are parked, there are two dumpsters. One is marked for trash only, the other for cardboard only.

For the amount of traffic a rest stop might receive does this seem inefficient to anyone else? Also, there where does the glass, plastic, and paper go? The rest stop sells all of these materials, but only recycles its cardboard.

--On a side note, the dumpsters are owned by Waste Management, the same company that the previous post mentions sponsored a PGA golf tournament. It looks like this company is pretty well diversified into the trash industry.
