In California, it is illegal to put them in the trash. Each area has it’s own way of handling this. In my town, they make it very easy, you just put them in a plastic ziplock bag (I use an old one) and tape it to the top of the mixed collection toter. We have to separate paper from the mixed stuff, but the mixed bin really covers most plastic, milk cartons, and metal. A third bin is for yard waste, but you can put things like pizza boxes in it. My trash is down to almost nothing for a family of 3. All are rolling toters, so that makes it even easier.
