12 MINERALS TECHNOLOGIES INC. NEW PRODUCT DEVELOPMENT DURING THE YEAR, Minteq developed a new high performance gunnable refractory  material for the Electric Arc Furnace market that was successfully  trialed at key accounts in North America. Paper PCC New Product Development Pipeline by Development Theme New Product Development Stages The new product development pipeline  for MTI’s Paper PCC business unit is  robust. In addition to new PCC products  for filling and coating paper, the business  unit is developing new technologies to  aid papermakers in waste management/ recycling, energy, the environment and  sustainability, and packing. These new  development areas are focused on helping  our papermaker customers reduce costs  and improve efficiency of their operations. As we view the market today, both of these  approaches for waste management and  operational sustainability represent a market  opportunity of about $150 million to $200  million. They also provide differentiators  for MTI, building upon the environmental  advantages we have already established  and provided for years as our PCC captures  CO2 from the stacks of our customers and  improves the air quality surrounding the  paper mill. We are aggressively pursuing  both market areas and expect to be trialing  products, framing the value and defining the  ultimate market for each in 2014.
