We have recently been getting calls in relation to disposing halogen light bulbs. The make up of a halogen bulb is basically the same as an incandescent. Some manufacturers call them incandescent bulbs. But these bulbs are the ones that have been used for many many years and do not contain any gasses that will escape from the bulb once broken. It's those gasses that can cause environmental damage.
As a result, there is no need to dispose of halogen bulbs in any way other than making sure that shards of glass don't cut anyone. Throwing these in with your regular garbage is just fine.
