Love how you folks are the ones that are hostile...
I read my links pal, and for your information, segregating waste with signs doesn't mean jack to those visitors that show up bringing all kinds of goodies. I have a sandwich and a cup from Subway and I care less where it lands, red or otherwise. It's gone to me. Furthermore, if not policed to the nines, the nurses that are overworked won't care where the hell it all goes.
My wife and i just had a baby and nearly every piece of trash generated while we were in the room was levied into a red bag, treatable or not.
So, the question is, buy a system that treats 3M pounds of waste and eliminate your RMW expense hauling or hire somebody like you to run around the hospital pointing in trash cans, yelling at the staff on the ground.
Let's chat after the 10Qs for 4th and 1st quarters, shall we?
