Computer e-waste is the fastest growing solid waste stream (SWS) in the world. It is harmful to human health and environment because of the hazardous nature of its contents. It creates a major disposal management challenge especially in the low-income countries. The study identified computer e-waste disposal management (CEDM) approaches; examined potential risks to human health and environment; assessed level of public awareness on potential effects; and explored possible environmental governance for its sustainability. businesses, ministries and agencies (MAs), disposal sites and households provided data for the study which was then analysed using SPSS. The findings revealed that MAs dispose of the e-waste through auction, throwing away into SWS, and donation; business sell to e-waste collectors, donate and lease out; households use storage, throw away into SWS, donate, sell as 2nd hand material and to recycling facility; e-waste pickers use urban mining and open-air burning; yard shop operators sell to local industries and export market. The level of public awareness on human health and environmental effects of CEDM approaches was low. All the approaches used except recycling by WEEE Centre were found to be unsustainable. The study recommends the creation of a CEDM Authority or a department created at the Communication Authority of Kenya or Nairobi County Office to implement a Zero Computer E-waste Policy. The policy will provide for establishment of: Residential/Commercial/Neighbourhood Computer e-waste drop-off points, County computer e-waste recycling centre, and Ward computer literacy centre for Community computer literacy capacity building.
