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.

Huh, everywhere I've lived has specifically excluded pizza boxes.

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.

>You can put your pizza box in recycling if it does not contain food residue. The liner should go in the trash.

This is another problem: what goes in what bin is different in every city. I still don’t know if cardboard goes in trash, recycling or organically in my new city. Standardize the rules.

it isn't just different in every city, they change everywhere, all the time, unpredictably.

the university i worked at had different recycling rules than the city it was located in, because they operated their own little recycling facility. by the time i left the sorting rules they handed out to all 10,000 employees quarterly consumed an 8.5x14 sheet of colored paper.

a local fast food restaurant has something like four different disposal bins, and i'm pretty sure that at least 3 of them aren't mutually exclusive in their descriptions of what they accept. none of the bins match my understanding of what any of the local waste disposal companies accept in a given stream.

Our recycle company specifically told us to throw pizza boxes in the recycling. I'm told there are some ways to still use it just not in making paper again.

Can't you just compost it?

They can probably be composted.

There could be concerns over potential toxins arising from the breakdown of the inks and adhesives used in making the boxes entering the food stream?
