Parkesine, a material predating celluloid, marked a significant leap in the plastics revolution. Alexander Parkes, driven by the lucrative challenge to find an ivory substitute, pioneered the development of the first synthetic plastic. His invention democratized consumer goods, providing a more accessible alternative for items previously made from scarce materials like ivory and tortoiseshell.
Society widely felt the ripple effect of Parkesine’s creation. No longer were the elegant piano keys or the combs that graced dressing tables the privilege of the few. Parkes’ ingenuity brought these luxuries within reach of the many, setting a precedent for the role of plastics in shaping consumer culture.
Bakelite: A Game Changer
With the advent of Bakelite, the plastics narrative took a decisive turn. In 1907, Belgian chemist Leo Baekeland created this heat-resistant, durable material—the first fully synthetic plastic. Bakelite’s invention was a game changer, introducing a material that was:
-
versatile
-
durable
-
heat-resistant
-
the birth of modern plastics
Dubbed the ‘material of a thousand uses,’ Bakelite found its way into everything from telephones to kitchenware, signaling a new era in the plastics revolution. Its ability to be molded into a myriad of shapes and forms demonstrated plastic’s potential to innovate across industries, paving the way for the future of manufactured plastics.
Plastic Production Boom in the 20th Century
The plastics industry experienced a significant growth spurt as the 20th century progressed. Innovations in plastic production yielded a constellation of new materials, such as polyethylene, polyvinyl chloride (PVC), and polystyrene—each with their own set of unique properties. This era of industrial production saw plastics become deeply integrated into the fabric of modern society.
The proliferation of plastics was not without consequence. The very qualities that made plastics so appealing—durability, versatility, and low cost—also made them a growing concern as waste began to accumulate. As we ventured into the post-war period, the plastic waste problem started to emerge as a shadow over the plastics revolution.
Petroleum and Natural Gas Contributions
Abundant fossil fuels quite literally fueled the explosion of plastic production. Crude oil and natural gas, the primary materials for plastic manufacturing, underpinned the industry’s expansion. The petrochemical industry’s appetite for these resources was ever-expanding, consuming hydrocarbon gas liquids and refinery olefins to produce the plastics that would come to define the consumer landscape.
This reliance on non-renewable resources, however, created challenges. The full life cycle of plastic production, from extraction to disposal, contributed to pollution and other environmental issues.
Diverse Applications of Plastics
Venturing into the 20th century, plastics found their way into virtually every aspect of daily life.
