They run big bulbs, thus the elements are of a decent hefty size and weight Now, we all know that the elements inside a bulb is of tungsten material, but rather fuzzy on the thorium topic - that an anode coated (or have thorium mixed in with the tungsten, I guess, if I heard right..) in thorium renders the tungsten not suited for recycling purposes. would this be a true statement? thx-Monte  |  IP: Logged Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 09-10-2011 10:57 PM                     Another reason for the lack of recycling could be the high melting temp. 3420 C. 6192 F.  |  IP: Logged Joris Springer Film Handler Posts: 83 From: Almere, Flevoland, The Netherlands Registered: Feb 2007 posted 09-15-2011 05:26 PM                     At the cinema where I work we have an underground waste disposal system. In the morning we just dump them down there, often with a big bang. Since it is a sealed compartment and no person has access to it unless they put the system in maintenance (and you can't open the hatch for it then), it is a safe way of throwing them out. Just need to handle the lamp carefully when you move it from the box to the hatch.  |  IP: Logged Bruce McGee Phenomenal Film Handler Posts: 1776 From: Asheville, NC USA... Nowhere in Particular. Registered: Aug 1999 posted 09-16-2011 09:49 AM                     My company doesent pay me enough to root through the dumpster to find the tungsten from my 2K and 4K xenons. I leave the lamps in the plastic case, and heave it against the inside wall of the dumpster. I'm always rewarded with a loud BANG! Thanks for reviving this thread.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 09-16-2011 02:57 PM                     Most welcome..and do agree, Bruce. I mainly dug this up to see if the blurb on the value of tungsten was valid or not for recycling.  |  IP: Logged
