Precious metals recovered from recycled televisions

By recycling televisions (TVs), waste is diverted from landfill and resources such as precious metals, plastics and glass are recovered.

Why recycle TVs?

TVs containing cathode ray tubes are one of the leading causes of lead contamination in municipal waste streams.

These tubes can contain up to four kilograms of lead and other toxic materials such as mercury, cadmium and arsenic.

Lead is a cumulative poison that can contaminate groundwater and have harmful effects on human and animal health.

What happens when TVs are recycled?

Some television components may still be useable, enabling certain parts to be directed into a reuse stream.

To be recycled, TVs must be broken down into their many different components.

Cathode ray tube (CRT) glass contains a high concentration of lead. This means it can't go back into the normal glass recovery process like glass bottles. CRT glass is typically crushed and cleaned.

One of the major reuses for CRT glass is in manufacturing new TV and computer monitors.

Circuit boards are shredded down to a fine powder and separated into plastics and precious metals. This material can be reformed into a range of products.

Plastic casings are shredded and tested for their composition. Once identified, the plastics can be melted and extruded for use in new products.

Scrap metals are typically melted down to form new metal-based components.
