That's a lot of weight to ship half way around the world for a very small return. I really doubt that many CRT's are not just sent to land fill. Chris -- Remove prejudice to reply.

A former colleague told me of an interesting experience he'd had in a former life (job) getting rid of a decommissioned mainframe. He had all sorts of quotes from people wanting to charge him for disposing of the kit, and a local scrap dealer offering to /pay/ him for it. It turned out that mainframes of that age had enough gold in their contacts for it to be worth recovering it (by dissolving it in cyanide, I gather -- don't stand downwind!). The cabinets would have been good for scrap metal, the rest was probably landfill. Cheers, Daniel.

I believe my local landfill disassembles the CRT TVs and monitors,and sends the PCBs to a recycler,and the CRTs go elsewhere for crushing and the glass gets reused. -- Jim Yanik jyanik at localnet dot com
