The recycling of CRT´s is one of the most complex tasks currently. The lead oxide is in the cone of the CRT and is collected and sent to India for the fabrication of new CRT´s. Also in Lead cast is used as silica and trap the cast impurities. I don´t now the costs but Dr. Tomas Prieto who is in this industrial field, told me that It is hope that in 10 years this lead oxide will be processed.

Hi, Dr. Benjamin.

But Does the lead oxide is collected or the milled glass is sent to India?

I think they send the CRT´s 

Recycling of lead oxide obtained from the TV´s glass bring economical benefits. Lead oxide nano-particles size of 40 nm to 50 nm could be obtained can have economic implications of global reuse and recycling .
