("The silos, which are scheduled to start operation in July, are designed to blend cleaner-burning imported coal with China’s own high-polluting domestic coal, which is contaminated with sulfur and dust. Coal blending will produce a mixture that will help electric utilities meet China’s steadily tightening environmental regulations.")
Note: The report states, "Blending 'is a sound solution to reducing greenhouse gas and pollutants emissions from coal-fired power plants,' said Howard Au, the director and chairman of Petrocom Energy Ltd., which owns the blending facility here."

CBF stands for Coal Blending Facilities.
For coal blending silo, I can not find this Chinese company in the Web. And after reading it, I still do not know how it works. Just blending and that is it?
