materials, such as wood, glass, metal and paper. Of the world total, Europe (including all the EU, plus Norway and Switzerland) contributed 61 M tonnes, North America contributed 58 M tonnes and China contributed 35.5 M tonnes.
For many applications, fillers and pigments are mixed with the base polymer resin to improve the appearance and/or performance of the final plastic product.
About 15.5 M tonnes of ground calcium carbonate (GCC) was consumed in plastics processing in 2007. This included applications in plastic film, sheets, fibres, moulding, thermosets, pipes, profiles and flexible PVC. Global talc consumption in plastics is also significant, running at 900,000-950,000 tonnes/y. This includes 160,000-170,000 tonnes/y of talc in the EU and a similar quantity in the US. Kaolin, wollastonite, barytes are also often used for specific purposes by the plastics companies.
