Estimation of dioxin emissions from cable burning in the greater Accra region • ~1000 tonnes / year burnt cables in Greater Accra Region • Thereof is ~38% plastic = 400 tonnes / year • Thereof is ~62% copper = 600 tonnes / year • Preliminary estimation of total dioxin (PCDD/F) emissions to air from open cable burning in the Greater Accra Region: • Source Strength = ~5 g / year • Compared with the European dioxin air emission inventory for 2005 (EU15 + Norway + Switzerland, Quass et al. 2004) this equals to: • 0.25 – 0.5 % of total dioxin emissions • 2.5 – 5 % of dioxin emissions from municipal waste incineration • 15 – 25 % of dioxin emissions from industrial waste incineration Ref: Quass et al. 2004: The European dioxin air emission inventory project – final results.

More than technology is needed • Having found the right e-waste recycling technologies doesn’t necessarily mean that an operation can be paid by the sales of recycling output fractions or materials. • A self-sufficient (profitable) recycling business can have two income sources: • Intrinsic value of the recycling output fractions or materials; • The “polluter” who pays for the proper recycling and disposal of his waste. • Sustainable recycling of e-waste will always demand for a proper managed framework and a financing scheme. © Empa/Switzerland, 24 November 2010

Conclusion © Empa/Switzerland, 24 November 2010 E-Waste volumes in African countries seem to be still low, however are relevant regarding environmental and socio-economic impacts and are increasing steadily. The informal sector can be highly efficient in the initial stages of the recycling chain, but looses valuable resources and are associated with adverse environmental and socio-economic impacts in the final stages. When including the informal sector, the formalization processes needs to be the main objective. A profitable (self-sufficient, sustainable, …) recycling business demands for a a proper managed framework and a financing scheme, which enables to solve the problem comprehensively (e.g. all e-waste categories) and react on changing conditions (e.g. cost factors)
