5. www.distrupol.com 5 Facts and Figures Over 2 millions tonnes of Plastics in Europe alone. The most widely specified material. More than 1000 plastics parts. On average, 100kg of plastics replaces 200- 300Kg of conventional materials. E.g. 4.2Kg lighter in Engine cover and 5Kg in Fuel tanks. Cuts oil consumption by 12 million tonnes and reduce CO 2 emissions by 30 millions tonnes/p.a. just in Western Europe.
