Funny you should say that because I'm an environmental studies major and we do, in essence, let small shops do exactly that. Most toxic chemicals are disposed of in residential and commercial trash because they are being disposed of in small quantities. You basically do have to exceed a certain threshold before certain regulations apply to your toxic waste, such as household batteries.

We encourage consumers to recycle tech. We sometimes tack on some kind of environmental related tax or surcharge to try to cover the cost, but it is paid up front, it is a small amount and we know the fee at the time of purchase. But we don't set bear traps that can ruin your life because you put an old computer in the trash can instead of disposing of it properly, for example.
