Old TV & monitors

The old “glass TV” using what in technology language is called a Cathode Ray Tube (CRT), was first launched as a commercial product in 1934 and has since then become a part of most global households. Although we do not see these old TVs and monitors in stores since the launch of flat panel displays, they will continue to be in use in many homes for long due to their long lifetime. Special applications also still use CRT-technology where advantageous.

CRTs are made of two types of glass, barium glass and lead glass. The barium glass is coated with a fluorescent layer, creating the picture and the lead glass is coated with ferrous oxide. The fluorescent layer contains several hazardous substances such as cadmium. The non-separated and non-cleaned lead glass is also classified as hazardous waste and thereby subject to specific requirements.

This is how it works

Careful handling of CRT-appliances (such as TVs or monitors) is necessary in order to avoid the glass from being crushed in transportation. In a special pre-treatment facility, the CRT-appliances are dismantled. Plastic covers, sometimes wood boxes, loudspeakers, cables, and circuit boards are separated from the remaining CRT-glass before further treatment in mechanical processes.

The first step in the mechanical treatment of the CRT-glass is washing, where the fluorescent coatings and ferrous oxides are removed. The cleaned barium and lead glass is then treated further.

About 90-95% of the glass is converted into secondary raw material in accordance with applicable environmental legislation. The material can then be used in production of new glass and lead products.
