[Aslug] Mercury lamp disposal?

[Bill Reid]

Hi everyone,
I have just replaced the lamp in my projector, and I want to know where to dispose of it responsibly in Alice Springs (for free). If anyone knows, I would greatly appreciate the information. I won't be at a LUG meet next week, I have to go to Melbourne and I missed the last one because it was so god-awful cold, but I am still around!!!
Thanks guys
Bill
