Lego - use recycled materials please! Lego, one of the world's best known toy manufacturers cranks out 20 billion Lego bricks a year. The plastic used in Lego is mostly acrylonitrile butadiene styrene, or ABS. Acrylonitrile is produced from propylene and ammonia; butadiene is a petroleum hydrocarbon and styrene monomers are derived from coal.
Acrylonitrile Butadiene Styrene, often abbreviated ABS, is the plastic used in most modern LEGO elements. Its chemical formula is (C8H8)xÂ·(C4H6)yÂ·(C3H3N)z, and it has melting point at about 105 Â°C. ABS is a thermoplastic consisting of a styrene monomer with the addition of an acrylonitrile momomer and a butadiene monomer. It is the butadiene component (a synthetic rubber mainly used in tires) that is largely responsible for the strength and impact resistance of the plastic.
