Kaolin (production)

The activity generating the emissions is kaolin production. The Reference Product is kaolin. The product "kaolin" represents 1 kg of kaolin produced using the wet process. Kaolin is a clay mineral, more precisely an aluminium hydroxide silicate which corresponds to the chemical formula Al2O3.2SiO2.2H2O. It is a naturally occurring weathered product of granite, sold for its whiteness, purity and physical and chemical properties. In the United States, about 70% of all kaolin produced by the wet process are used as filler or coating in the paper industry. Other industries using this mineral are, for example, the ceramics industry (for whiteware, sanitary ware, insulators, refractories), the paints and inks producers (extender pigment) or the rubber and plastics industry (functional filler material). The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity.
