On a daily basis, paper companies are faced with enormous pressures to reduce their environmental discharge. Sources of "pollution" can come from air emissions, wastewater, landfill, and even thermal pollution. In the aggregate, the cost of reducing or eliminating these sources of pollution runs into the billions of dollars and the standards to meet discharge specifications continue to become more stringent.
Specialty Minerals Inc. (SMI) is fully aware of the difficulty faced by paper mills in meeting environmental compliance. For many years, we have worked with paper companies to design products and programs that are environmentally friendly. For instance, we offer an alternative, phosphate-free, acid-tolerant chemistry suitable for neutral or weakly acidic groundwood papermaking. In conjunction with the AT® precipitated calcium carbonate (PCC) system, our phosphate-free, acid-tolerant process eliminates one more source of this chemical species.
When SMI manufactures PPC, waste CO2 is reacted with lime. Hence, the process consumes CO2 and reduces its discharge into the air. World governments are currently discussing the limits on industrial CO2 discharge, how to reward users of CO2 via credits, while charging emitters. SMI is actively engaged in the discussions of CO2 credits and debits with paper mills and lime suppliers.
