typical of a haul from the Baltimore collectiveI don't know how possible this is everywhere, but some friends and I have been trying to create an infrastructure for catching useful waste before it gets to the dump. Dumpster diving is by no means new, but it's becoming more profitable and important as our businesses throw away more and more useable material. A lot of what's there to be had is edible food, but dumpsters also provide household goods, flowers, clothes, you name it.
My friend Mike started a
collaborative website for Baltimore and organized a weekly collective to make the endeavor more profitable for everyone. Members meet at his house Tuesday nights, or coordinate via a listserv, to divide into pairs or groups which each go to a different dumpster. Since it's most common to find a whole lot of one kind of thing (bagels, juice, produce) at one dumpster, they collect as much as they can and meet back at the house to divide it up. That way, everyone gets a reasonable amount of each category and ends up with a balanced haul.
Of course, dumpster diving is a pretty maligned practice, which leads to some risks. The legality issue is kind of fuzzy, and one has to be especially careful of trash trucks coming to empty the dumpster. (That's another advantage of the collective: the buddy system works, and we can publicize collection times.) The most common concern is food safety, but I think most people would be surprised at how much food is thrown away in almost-perfect condition and in clean plastic containers.
So grab a buddy, empty out your car, and head on down to the local supermarket or cafe. It might take a while to find a location with a reliable source, but once you do it's amazing how much free food you can get out of a fundamentally flawed system.
ETA: my roommate Wes and I did a walking tour of the dumpsters in our neighborhood, which didn't yield much besides a nice Sunday afternoon stroll. But, I did stop in at the Subway to ask them straight-up if I could have the bread they would otherwise throw away at the end of the day. The guy behind the counter seemed dubious but said if I came back at 15 minutes to closing (9:45) he would see what he could do. When I went back just now, he filled a plastic bag the size of a grocery sack with 13 loaves of slightly-stale (just the very ends) bread. I hung it on my handlebars and pedaled home with garbage-juice-free bread!
