Some researchers want to recycle
a chemical in computer screens to
use it for a medical treatment.
Shawn Allee reports:
Most LCD computer screens contain toxic mercury. The European Union will soon mandate those screens be recycled rather than thrown away.
There are other metals and chemicals in the LCD screens that are not dangerous.
Dr. Avtar Matharu is with Britain’s University of York.
His research team recovered polyvinyl alcohol from the computer screens.
It’s used in spongy pads that deliver medicine.
“We can take out Polyvinyl alcohol from the front and back of an LCD screen. We can take what effectively would be a waste resource and potentially use it in a medical application.”
Matharu says getting polyvinyl alcohol out of LCD screens is expensive compared to making it from crude oil, but he says it could be another reason to recycle rather than throw them into a landfill.
