One of the smarter things my local co-op has established is a dumpster dedicated to bikes at the local landfill/transfer station (in my day as a kid, we called it the "dump").
Its a big metal bin near the front with good signage so people know not just to place bikes in the bin, but where the bike will end up.
Best bike found in it…1980 DeRosa size 59
Worst Bike: Lots of washers and dryers for some reason.
We try to check it daily before the scrap metal thieves remove items, although they are welcome to any home appliances.
