These are good for Burning Man because sorting recylables is necessary if you want to drop them off (and free up some space in your car) in Reno on the way home. They have to be sorted or it will all go into the trash. These are collapsible, so they don't take up much space in the car. And for your non-recycling savvy friends, it makes it much easier. You can take the role of emptying into their proper bags when necessary.
