I've noticed a lot of people lately driving up, riding up (on bicycle), or walking up to the residential dumpsters behind my apartment building and either climbing up on the side, reaching in, grabbing bags, tearing them open and rummaging through them----or climbing on top of the dumpsters, opening the panels on top, jumping into them and rummaging through everything in them, throwing whatever doesn't "interest them" aside.

Now..... are these folks prospectors or what?  And whatever do they hope to find in a residential dumpster anyway-----"the hidden jewels of Ali Babba"?

No-one's going to find anything in a residential dumpster that isn't either in ten pieces, threadbare, burnt-out, or smothered in coffee grounds and glop.
