All told, the local government estimates that Guiyu processes 1.5 million tonnes of e-waste each year but nets less than $10 per week for the workers. This low cost drives many recycling operations to export American e-waste—nearly four million tonnes of it each year. Much, inevitably, ends up in toxic processing centers like Guiyu.
