The need for synthetic ivory
The discovery of plastics was triggered by the need for synthetic ivory, among other factors. Ivory has been valued for centuries for its ornamental and practical uses, mainly due to its white colour when processed. It has been used to make a variety of items, including piano keys, bagpipes, buttons, and ornamental objects. However, the demand for ivory led to the slaughter of wild elephants, with approximately 700 elephants killed in 1930 to acquire 40 tons of ivory. This prompted the search for a synthetic alternative.
The first synthetic polymer was invented in 1869 by John Wesley Hyatt, inspired by a New York firm's offer of $10,000 for a substitute for ivory. Hyatt treated cellulose derived from cotton fibre with camphor, creating a plastic that could be crafted into various shapes and imitated natural substances like ivory. This discovery was revolutionary as it freed human manufacturing from the limits of nature.
The development of synthetic ivory was further driven by the growing popularity of billiards, which strained the supply of natural ivory. Synthetic ivory provided an alternative that met the aesthetic requirements while being free of the blemishes of natural ivory. It also addressed the high price of ivory, making it more accessible to customers.
Despite the benefits of synthetic ivory, it has not successfully curbed the illegal trade of natural ivory. The similarity between synthetic and authentic ivory has allowed unscrupulous traders to pass off synthetic ivory as genuine or claim that smuggled ivory is synthetic. As a result, synthetic ivory has not proven to be the solution that conservationists and enforcement agencies hoped for.
While the initial need for synthetic ivory may have triggered the discovery of plastics, it is important to note that the plastics industry has expanded far beyond this initial application. Plastics have become an essential part of our lives, with various synthetic polymers revolutionising manufacturing and consumer products.

World War II
The plastics industry was already establishing itself as a key part of the future in the late 1930s, with new materials like Bakelite, polystyrene and polythene already developed. However, World War II accelerated the manufacture and use of plastics, which provided the foundation for the industry's rapid expansion in the post-war period.
During the war, there was a scarcity of traditional materials like steel and rubber, which were essential for the war effort. Plastic was used to fill the gap in consumer goods. For example, combs, which were usually made from hard rubber, were now made from plastic. Plastic was also used in countless applications to support weaponry, including cords for parachutes, liners for helmets, and components for aircraft.
The need for durable, inexpensive, lightweight materials that could be manufactured quickly also contributed to the increased use of plastic during World War II. Nylon, for instance, was used for parachutes, ropes, body armour, helmet liners, and more. Plexiglas provided an alternative to glass for aircraft windows. Newly created expanded polystyrene was used for thermal insulation and shock absorption in vehicles, and PVC was used to make everything from canvas for tents and water-repellent coatings for uniforms to hand grenades and tank components.
Plastic production in the United States increased by 300% during the war, and the surge continued after it ended. With the post-war economic boom, consumers had more money to spend, and plastic goods could be produced quickly and affordably. Products that used to be a luxury became more accessible to people worldwide.
The legacy of World War II was that the world not only understood much more about the manufacture and use of plastics but had also developed the skills and capacity for innovation in the industry.
