China's toxic waste in solar energy
Washington Post: China is rapidly becoming a leading manufacturer of solar-cells. Unfortunately, the highly toxic waste -- silicon tetrachloride -- from the production of polysilicon, which is used to make solar cells, is polluting ground water and the surrounding villages around the plants. Unlike in the West where stricter environmental regulations are in effect, solar plants in China have not installed technology to prevent pollutants from getting into the environment or have not brought those systems fully online, writes Washington post reporter Ariana Eunjung Cha.
"The land where you dump or bury it will be infertile. No grass or trees will grow in the place. . . . It is like dynamite -- it is poisonous, it is polluting. Human beings can never touch it," said Ren Bingyan, a professor at the School of Material Sciences at Hebei Industrial University. Shi Jun, a former photovoltaic technology researcher at the Chinese Academy of Sciences estimates that Chinese companies are saving millions of dollars by not installing pollution recovery. "If this happened in the United States, you'd probably be arrested," he said.
