Require all merchants selling CFL light bulbs to offer instore disposal receptacles for returned expired bulbs.
Encourage returns by having a returnable deposit on each bulb - similar to that imposed on can/bottle returns.
Why is this important?
little seems to be done to avoid our coastal waters becoming contaminated w/mercury. There is no separate refuse collection for these items, the only way to safely dispose of them is to drive to the city recycling plant - I believe most people are just tossing them in their garbage where the mercury contaminates the soil and ultimately enters our waterways to the detriment of fish & bird life and us when we consume the fish. I suspect many do not know that these bulbs contain mercury or the damage that it will cause.
