CRT monitors

[dtectr]

When he dismantle crt he can cut screen on two pieces - one (the front of screen) is normal glass only the back part is lead-glass. That one is then cut to granule size and used mostly as component in building roads.

This is important - one (the front of screen) is normal glass only the back part is lead-glass - can someone verify the accuracy of this? i was wondering about the same thing - two industry methods for processing these involves opening them to remove phosphors. Both seperate on that imaginary line, but both halves are placed in the same container for disposition, so I don't know.

the problem with "road building" use, at least according to EPA, is that lead can leach out of the glass & into groundwater. That's a stretch, I think, but I'm not the scientist.

Well I am not an expert too I can only toss in what I learned from my friend and how he does things. According to him the biggest amount of lead or percentage of lead on crt is on back part of glass which is usually thick painted - that paint is actually what we speak about -lead.

This may be true, but I think what it boils down to is supply and demand. The supply is enormous while the demand is not.

Yes. That is why they are storing this glass (broken to small pieces) and wait for solution. Other values are fully recovered and maybe later somebody will figure out how to get rid of that elephant in a room.
