E-WASTE
-
Recycling is often done by hand because the equipment has to be separated into its various parts such as power supplies, circuits and plastics
-
The disadvantage is that labour is cheapest in countries which have the lowest health and safety standards é-waste often contains contaminants like head,cadmium,beryllium and mercury
-
Automated recycling systems use magnets and eddy currents to separate metal,glass and plastic parts.
Glass from CRTs is reused in car batteries and ammunition and the plastic parts are sold to plastics recyclers
Audiovisual components, television,VCRs, stereo equipment,mobile phones,other handheld devices and computers components contain copper and gold
Extracting these metals from circuits board is a major challenges for the industry because recycling efficiency is low.
Reusing e-waste and not recycling or dumping it is probably the best approach to WEEE for a number of reasons
Firstly, it reduces the demand for new products and therefore reduces the use of raw materials, energy and wafer that go into the production process
Thirdly , the use of technology can spread to poorer sections of society.
The skills needed to repair and maintain equipment are kept alive and the components eventual journey to a landfill site is postpones.
Secondly, cardboard and plastic are saved from the packaging process
