David can handle some 70,000 tons(150 million pounds) of electronics a year. Although this is only a fraction of the total, it wouldn't take many more machines like David to process the entire U.S.A.'s output of high- trash. Unfortunately, under current policies, domestic processing of e-waste is not compulsory, and while shipping waste abroad is ethically questionable, it is still more profitable than processing it safely in the U.S.A.
