Our condo building also lets paper, plastics, glass, and cans in the same bin, so it's very easy. However, I recently learned we're not allowed to put #6 in the bins. Most plastics have a recycle triangle with arrows that go around with a number inside the triangle. #6 are the polystyrene containers, such as the to-go containers from restaurants, or some egg cartons, such as Eggland's Best cartons.
