In Delaware, there is a very good volunteer recycling program that got just a little better. You can now recycle using “single stream (except if it's batteries, corrugated cardboard, plastic bags). They've never accepted polystyrene. I've always felt guilty about stuffing the light as a feather but bulky stuff in the garbage.
Luckily, there's a company that will accept polystyrene (solid or peanuts) and recycle them into, well, more packing material. At least it gets a second chance at usefulness.
