There's certainly a market, but the process of manufacturing and recycling them is difficult to do in compliance with modern environmental regulations. In particular, the leaded glass is problematic to export for recycling.
- mrob 3y agoLeaded glass is not required for CRTs. In the case of color CRTs, it was only used for the backs and sides, because x-rays make leaded glass turn brown. The faceplates used barium-strontium glass, which I assume was more expensive. This sample chapter from "Image Performance in CRT Displays" by Kenneth Compton provides some details: https://spie.org/samples/TT54.pdf https://spie.org/samples/TT54.pdf I see no reason why you couldn't make the whole thing from barium-strontium glass.
- dharmab 3y agoThe existing regulations assume that all CRTs are leaded, so you'd have to lobby multiple governments to treat your product differently.
