Warning: my neighbor in Duluth bet me $50 that our street's recycling bins don't matter. Here's what happened.
He kept saying one household's sorting means nothing next to factory emissions, so I tracked our block's bins for 6 weeks and we were tossing half of it in the trash bin anyway. One Tuesday I pulled 14 greasy pizza boxes out of the paper bin by myself, and he quit laughing after that. Has anyone else actually counted what their building gets wrong, or is it just me?
