European Parliament and of the Council of 27 January 2003, on waste electrical and electronic equipment (WEEE), UNU, Bonn (2002).

Waste of electric and electronic equipment (WEEE) includes not only the equipment itself, but also all the components, subassemblies and consumables which are part of the product at the time of discarding ( European Union, 2002 European Union Directive, Directive 2002/96/EC. Three out of six parameters were capable of satisfactorily removing the lead and turning the post-procedure waste lead-leaching safe.Д¬athode ray tube computer monitor lead removal recycling WEEEД®lectrical and Electronic Equipment (EEE) is - but is not limited to - equipment which is dependent on electric currents or electromagnetic fields in order to work properly. The results reveal that vacuum atmosphere and the addition of 5% carbon graphite as reducing agent are optimum conditions to turn the CRT into a non-hazardous waste. Moreover, six optimum thermal lead removal procedures were performed and the NBR 10005 procedure was repeated. The CRT panel is lead free, while the CRT funnel and neck have about 20% of lead oxide in their composition.

The results show all samples are hazardous according to local environmental law (NBR 10004) due to lead leaching. The standard NBR 10005 procedure was performed for 7 different monitors. In this CRT study, a natural leaching simulation (NBR10005) was performed to determine the toxicity of this e-waste. These devices became obsolete because of emerging technologies such as LCD, LED and plasma thus generating a huge stockpile of e-waste worldwide. Cathode ray tube (CRT) monitors are electronic equipment mainly made of glass, polymers and metals.
