What is e-Waste?

e-wasteE-waste (electronic waste) is a popular and informal name for electronic products that are obsolete or unwanted. TVs, monitors, computers, copiers, fax machines, audio and video equipment, are some of these common electronic products.

E-waste is the fastest growing segment of waste steam in the World. Many electronic products contain high levels of nickel, lead, and other toxic elements that render them hazardous waste when disposed.

While some naturally occurring substances are harmless in nature, their use in the manufacture of electronic equipment often results in compounds which are hazardous (e.g. chromium becomes chromium VI). The following list gives a selection of the mostly found toxic substances in e-waste.

Substance Occurrence in e-waste
Halogenated compounds:
– PCB (polychlorinated biphenyls) Condensers, Transformers
– TBBA (tetrabromo-bisphenol-A)- PBB (polybrominated biphenyls)- PBDE (polybrominated diphenyl ethers) Fire retardants for plastics (thermoplastic components, cable insulation)TBBA is presently the most widely used flame retardant in printed wiring boards and casings.
– Chlorofluorocarbon (CFC) Cooling unit, Insulation foam
– PVC (polyvinyl chloride) Cable insulation
Heavy metals and other metals:
– Arsenic Small quantities in the form of gallium arsenide within light emitting diodes
– Barium Getters in CRT
– Beryllium Power supply boxes which contain silicon controlled rectifiers and x-ray lenses
– Cadmium Rechargeable NiCd-batteries, fluorescent layer (CRT screens), printer inks and toners, photocopying-machines (printer drums)
– Chromium VI Data tapes, floppy-disks
– Lead CRT screens, batteries, printed wiring boards
– Lithium Li-batteries
– Mercury Fluorescent lamps that provide backlighting in LCDs, in some alkaline batteries and mercury wetted switches
– Nickel Rechargeable NiCd-batteries or NiMH-batteries, electron gun in CRT
– Rare Earth elements (Yttrium, Europium) Fluorescent layer (CRT-screen)
– Selenium Older photocopying-machines (photo drums)
– Zinc sulphide Interior of CRT screens, mixed with rare earth metals
Others:
– Toner Dust Toner cartridges for laser printers / copiers
Radio-active substances– Americium Medical equipment, fire detectors, active sensing element in smoke detectors
