Re: Chinese polysilicon manufacture

Am certainly concerned with pollution, but we're not going to assert that all polysilicon companies in China are polluters. 

The only offending silicon co. identified by name in the article is Luoyang Zhonggui High-Technology Co. The article quotes a couple of sources suggesting that other companies in China might be doing the same, but doesn't go so far as to suggest what percentage of them might be dumping, nor does it accuse any other specfic company.

Another of the Post's sources said some Chinese plants are stockpiling the hazardous substances in the hopes that they can figure out a way to dispose of it later. Stockpiling is far from ideal, but it's not pollution unless it's released.

We're not going to damn all polysilicon makers in China because of the irresponsible actions of only one. Chinese silicon companies are chasing profits and trying to speed their products to market, but we're not comfortable asserting to our readers that they're ALL dumping silicon tetrachloride between cornfields and playgrounds just because one got caught doing it.
