Baekeland was trying to mimic shellac, a natural polymer secreted by the Asian scale beetle and used at the time to coat electrical wires. In 1909 he patented a mouldable hard plastic that he called Bakelite, and which made him very rich indeed.
Chemists were soon experimenting with variations, breaking down the long hydrocarbon chains in crude petroleum into smaller ones and mixing them together, adding chlorine to get PVC, introducing gas to get polystyrene. Nylon was invented in 1935 and found its first application in stockings, and then after the Second World War came acrylics, foam rubber, polythene, polyurethane, Plexi¬glass and more: an incredible outpouring of new plastic products and the revolution of clear plastic food wraps and containers, which preserved food longer and allowed people to live much further away from where it was produced.
Single-use plastic bags first appeared in the US in 1957 and in British supermarkets in the late 1960s; worldwide there are more than a trillion manufactured every year, although the upward trend is now levelling off and falling in many countries, including Britain. We reduced our plastic bag use by 26 per cent last year, to 9.9 billion. Bottled water entered the mass market in the mid-1980s. Global consumption is now 200 billion litres a year and only one in five of those plastic bottles is recycled. The total global production of plastic, which was five million tons in the 1950s, is expected to hit 260 million tons this year.
Look around you. Start counting things made of plastic and don't forget your buttons, the stretch in your underwear, the little caps on the end of your shoelaces. The stuff is absolutely ubiquitous, forming the most basic infrastructure of modern consumer society. We are scarely out of the womb when we meet our first plastic: wristband, aspirator, thermometer, disposable nappy. We gnaw on plastic teething rings and for the rest of our lives scarcely pass a moment away from plastics.
The benefits of plastic, most of which relate to convenience, consumer choice and profit, have been phenomenal. But except for the small percentage that has been incinerated, every single molecule of plastic that has ever been manufactured is still somewhere in the environment, and some 100 million tons of it are floating in the oceans.
