PAGE THREE: SUMMARY The story of plastics over PLASTICS ARE the last 75 years is one of PRACTICAL insatiable growth driven by plastic’s prized properties and low costs compared with other materials. Demand for plastic, and From 1950 to 1990 global other materials production of plastic increased sixty-fold (from 1.5 to 90 Mt), compared with four times for Plastic 350 Cement steel, nine times for glass, and twelve times for aluminium. Aluminium Glass Growth has continued steadily from 1990 until today, with production increasing by three and a half times worldwide, as 250 Steel seen in Fig.2. During this period, Fig.1 Global annual primary plastic production, by end-use. plastic demand outpaced steel, glass and aluminium, and kept abreast with cement. Plastics are a uniquely practical The attractiveness of plastics production increasing from 1.5 x 1990=100 Much of this growth in demand group of materials. They are has led to rapid growth in the Mt in 1950 to 438 Mt in 2017 inde has been driven by increasing strong, lightweight, flexible and global plastics industry (Fig.1). (Fig.1).
