I have single stream recycling and the shit that people put into it is ridiculous sometimes. Greasy pizza boxes are a popular one.
In Minneapolis, greasy pizza boxes specifically go in organics recycling (aka "municipal compost"). Chicken bones and dairy products too - It's amazing what you can put in there. http://www.ci.minneapolis.mn.us/solid-waste/organics/index.h...
I just checked our website again, and the flyer I remember seeing is gone, replaced with one that says pizza boxes are recyclable now. "No food residue. No liner." Accompanied by a picture of a clearly never used pizza box.
So now I'm not sure. Is oil soaked into it OK as long as you scrape every last bit of solid food out of it? Do you need no food residue (literally impossible), or is a small amount acceptable? I'm more informed than when I started, but still uncertain.
Apparently we can't recycle shredded paper, that's news to me. This list is now standardized across all of Connecticut. You can search an item and see what to do with it.
