Beijing's black market alchemists

Zhao Dapeng has spent the last 11 years illegally soliciting used electronics door-to-door - earning more than he can farming in Henan province and more than Beijing's licensed e-waste recyclers.

"Broken or just old, be they computers, TVs or cell phones, I scrap them," the 42-year-old says.

He earns three times more collecting e-waste than he did growing corn and wheat in his hometown, he explains.
