Speaking of dumpster diving, if you do some
diving,
 what sort of companies do you target? 
 Public Recycling centers for local cities.
 A recycling service provider who rolls off others'
    Dumpsters under contract.
 A dumpster on private property makes me nervous,
 as in illegal trespass nervous.

Some places you can't legally go dumpster diving.  Around here
if it goes into a dumpster it belongs to the waste management
company.  You can't even legally retrieve an item from the
dumpster that you are renting from them.  I would have to tell
them to remove their dumpster from my property now if not sooner
if they made a row with me over something like that.
