I feel bad for all the sorters that have to sift through trash, who know most of the stuff will just get thrown in the landfill. Some people treat the recycle bin as a second trash can.
Especially on trash day when dog walkers go out of their way to throw their doggie bags in recycling bins on the sidewalk rather than the trash bin next to them.
There's no real punishment for missorting recycling, but I guess it's hard to prove who did what when trash collection is the way it is.
