i think that the following is probably the best way to do it:

- put glossy or painted cardboard, metal and glass in this blue bin

- compost any unmarked paper with your compost

- if your plastic has a number on it, save it and get it to a recycling facility

- otherwise, throw anything with this "how2recycle" label on it in the garbage to get it into a landfill instead of an incinerator.
