Flat Screen Monitors

Flat Screen Monitors

According to a document issued by the OECD working group on waste prevention and recycling, entitled “Technical Guidance for the Environmentally Sound Management of Specific Waste streams: Used and Scrap Personal Computers” LCD screens can be sent to a smelter for recovery of non-ferrous metals on the condition that the smelter is equipped with flue gas cleaning systems (to minimise dioxin emissions), and prepared to carry out the separation or immobilisation of mercury.

Flat panel screens should be sent for either recovery operation or thermal treatment at an environmentally sound and appropriately authorised incinerator with modern flue gas cleaning systems. When discharge lamps are removed, they should be sent to a specialised mercury recovery facility or to an environmentally sound and appropriately authorised hazardous waste incinerator with modern flue gas cleaning systems that guarantees the proper separation or immobilisation of mercury. The WEEE Directive requires that liquid crystal displays of a surface area greater than 100 cm2 are managed separately, as they are back lighted with gas discharge lamps containing mercury.
