Worth US$1.5 billion, Zhang Yin built her fortune on scrap paper. Specifically, hauling trashed paper and cardboard from the US to China to be recycled into boxing, and then typically stuffed with Made-in-China goods and sent back to the US. This perpetual-motion machine produces for her company, Nine Dragons Paper, US$1 billion in annual revenue.
The New York Times’s David Barboza has written a profile on Zhang, who is apparently uncomfortable giving interviews and doesn’t grant them often. As she is now one of China’s highest-profile wealthy citizens, she has reason to be wary. Those who make the infamous "China Rich List" have a tendency to be scapegoated by the government.
