Could the dumpster owners go and pick through with the purpose of recycling? Sure! If they wanted to...
It just not possible,in my opinion,or cost effective. I have seen to many loaded to the brim that had
no value orther than landfill material.I could see the owners of the dumpster denying any request to enter if you
were to ask.Everyone seems afraid of liability,can't blame them. But the contractor on the orther hand that rented
it,look the orther way,now they can possibly get more bang for there buck,because a recycler just removed
material making room for more.Myself I put most recyclables to the side of the tub and always disappears.
