About Greystone
Since 1936, Meckley’s Limestone Products, Inc. in Herndon, Pennsylvania has been a leader in the limestone processing field, and has been providing pulverized sorbent to the power industry since CFB technology was introduced in the United States in 1982. Formed to function as a developing arm, Greystone Materials, B.T. has taken the lead of this very specialized core competency since its founding in 1993.

 Colver Power Facility
Functioning as designer, builder and owner/operator for on-site limestone pulverizing facilities, Greystone’s first installation was completed at the Colver Power Facility in Colver, Pennsylvania. Requirements for this project included building the pulverizing facility, negotiating the raw sorbent contract for the power project, providing operating services and managing the raw sorbent purchasing and delivery.
