Group Performance by Region and Country

Total sales of ProAsh^®, derived from the Company’s proprietary ash beneficiation process, and ash from unprocessed sites increased, making 2012 a record year of performance for ST. Market demand remained strong, but limited ash supplies constrained ST’s output below its potential.

Outside the U.S., ST’s proprietary technology is now in use in the ash and industrial minerals sectors in Canada and Europe. At the end of 2012, another milestone was reached with the sale of an ash separator to a utility in South Korea, the first installation outside North America and Europe.
