My friend the eco-living expert said "juice boxes are pretty much the worst thing you can buy."
They are made of an aluminum-petroleum substance (for the lining of the paper carton) that is impossible to recycle because you can't separate the metal from the petroleum. And the paper is most likely virgin paper. And there's a plastic straw in a plastic wrap. Imagine everything that goes into making a juice box.
You should also never buy a carton with a metal lining (or any other flexible metal, like juice 'pouches'). Plain paper cartons are compostable, so they are fine.
I had never thought about this before!
There are times when you need small servings of juice (for a kids' party, for example). She says to get the small cans of juice. Remember those? With the pull tab? They are recyclable.
