Five years after building a 70,000 square-foot facility in Lexington, Kentucky, Birtley Industrial Equipment, a wholly owned subsidiary of Shandong Borun Process Industrial Technology Co Ltd, is on the path to expand its business and prosper. Over the past year, as the coal industry recovers in the United States, Birtley's coalrelated business has revived. Moreover, the company now enjoys a wider scope of operations, especially by doing an increasing number of environmental projects in China. The company is also doing better than before in its primary business of producing coal washing equipment, Zhao said. He said that in the coming year, Birtley may explore some environmental projects in the United States.
