Fluorescent bulbs contain a small amount of mercury and should not be placed in the regular trash. CFLs can be recycled for free at Lowe's stores. Some local Batteries+Bulbs accepts and recycles all types of bulbs and ballasts. Bulbs from businesses should be recycled using a bulb recycler or hazardous waste company. Incandescent bulbs, LED and halogen bulbs go in the regular trash.
