NEW YORK, NY, August 24, 2015-Minerals Technologies Inc. (NYSE: MTX) has successfully begun operation of a new satellite plant to produce the breakthrough NewYield(TM) Integrated Process Technology for the Sun Paper Group's pulp and paper operations in Shandong Province, China.

"We are extremely pleased to have our new satellite plant at Sun Paper up and running and producing a useable papermaking filler that provides Sun with both cost savings and reduced environmental impact, while at the same time providing them with a filler pigment for their paper," said Joseph C. Muscari, chairman and chief executive officer. "The successful commissioning of this plant now sets the stage for MTI to roll out this new technology to other papermakers."

NewYield(TM) is an innovative technology that converts a paper and pulp mill waste stream into a functional pigment for filling paper.
