Incandescent and Halogen Bulbs are not recyclable in any way. So, they should be placed into your general waste bin. Make sure that they are wrapped up to avoid any kind-of injury. CFLs (Compact Fluorescent Lamps) should be disposed of in the general waste bin as they contain poisonous mercury. Therefore, they should be disposed of separately. On the other hand, LEDs can be disposed of in your recycle bin, no harm done.
