Example e-waste generation in Nigeria / Ghana Breakdown of imports Breakdown of WEEE arising new Domestic e-waste Approx 650,000 tonnes used - good quality E-waste from used EEE of unclear quality Approx 350,000 tonnes used - bad quality broken / repairable directly imported e-waste Approx 250,000 tonnes (~5% of WEEE in EU15) broken / not repairable Source: SBC 2012 © Empa/Switzerland, 20 July 2009

Key message 2 E-waste can contain hazardous substances and its improper treatment leads to adverse effects for human health and the environment © Empa/Switzerland, 20 July 2009

Hazardous substances in EEE Occurence in EEE Possible adverse effects PBDEs, PBBs Flame retardants in plastics Hormonal effects, under thermal treatment possible formation of dioxines and furanes Polychlorinated biphenyls (PCB) Condensers, transformers Cancer, effects on the immune system, reproductive system, nervous system, endocrine system and other health effects Chlorofluorocarbon (CFC) Cooling units, insulation foam deleterious effect on the ozone layer -> increased incidence of skin cancer / genetic damage Americium (Am) Smoke detectors radioactive element Antimony carcinogenic potential Arsenic gallium arsenide inlight emitting diodes skin diseases, decrease nerve conduction velocity, lung cancer Barium Getters in CRT brain swelling, muscle weakness, damage to the heart, liver and spleen Cadmium NiCd-batteries, fluorescent layer (CRT screens), printer inks and toners symptoms of poisoning (weakness, fever, headache, chills, sweating and muscular pain), lung cancer and kidney damage Chromium VI Data tapes, floppy-disks irritating to eyes, skin and mucous membranes, DNA damage Lead CRT screens, batteries, printed wiring boards vomiting, diarrhea, convulsions, coma or even death, appetite loss, abdominal pain, constipation, fatigue, sleeplessness, irritability and headache Mercury Fluorescent lamps, some alkaline batteries, switches brain and liver damage © Empa/Switzerland, 20 July 2009

Improper treatment of e-waste (e.g. India / China)

Example dioxine emissions from cable burning Dioxine emission from cable burning is one of the main issues in many developing countries Observation Accra/Ghana ~200 kg cable are burnt per hour 10-20% from e-waste (rest mainly from cars) Extrapolated to West Africa 3-7 % of total European Dioxine emissions to air © Empa/Switzerland, 29 March 2011
