e-waste dumping in Africa

According to a UN report, an estimated 50 million tons of electronic waste generated globally every year, e-waste and its disposal is a growing problem, and much of it is dumped in Africa [link]. The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal is a treaty on waste disposal entered into force in 1992 [link]. It is estimated that

anywhere between 25 to 75 percent of the e-waste that enters Africa, mostly through Mombasa, Lagos and Dar es Salaam ports, is useless.
It is also reported that in Nigeria alone, about 500 containers full of used electronic cargo pass through the Lagos port every month, according to a recent study by Seattle-based Basel Action Network.
