Woodsman, Spare That Tree and Recycle Coal Ash Instead

摘要

February's issue of Power Engineering featured a story on efforts to increase the reuse of coal combustion products (CCPs). Traditionally, ash, slag and scrubber sludge have been re-used for about a dozen applications, the largest of which are for the manufacture of cement and aggregate, and for road construction. Now, there may be a brand new use for CCPs, one that could not only become one of the biggest single uses of coal byproducts, but one which would save trees as well.
