Special dustbin that's red coloured are used. Only specialised for radioactive or highly reactive metals. Like lithium ion cells, bulb , tube light also have inert gases like argon, krypton, etc and they cannot be recycled periodically. I know that is a heavy and reactive metal or inert gasses and cannot be dumped on green or blue. So nowadays red dustbins are appearing. And you can't dumped that metal on streets or in scrapyard or in some junkyards or whatever. But it may useful for the local itself..
