Especially over the last 50 years, plastics have saturated our world and changed the way that we live. The first synthetic polymer was invented in 1869 by John Wesley Hyatt, who was inspired by a New York firm’s offer of $10,000 for anyone who could provide a substitute for ivory.

Plastics: a story of more than 100 years of innovation. Since the dawn of history, humankind has endeavoured to develop materials offering benefits not found in natural materials. The development of plastics started with the use of natural materials that had intrinsic plastic properties, such as shellac and chewing gum. The next step in the ...

The development of plastics has evolved from the use of naturally plastic materials (e.g., gums and shellac) to the use of the chemical modification of those materials (e.g., natural rubber, cellulose, collagen, and milk proteins), and finally to completely synthetic plastics (e.g., bakelite, epoxy, and PVC).

There was, of course, plastic production prior to the Second World War, but the amount was insignificant from a historical perspective. During the Second World War, plastic production started to increase due to growing shortages of other materials and plastic’s ability to be used instead. After the end of the war, plastic producers started to look ...
Plastics are used for virtually all types of products and owe their popularity to their low cost and technical versatility. Plastic dominates packaging, is used widely in construction, transportation, electrical and electronic equipment, agriculture, and also very common in furniture and other household items, leisure and sports goods, as well as m...
Plastic waste is generated during production processes and after the plastic-containing products reach the end of their lives. Production of plastic-containing goods typically involves a whole series of processes, such as monomer production, polymerization, part forming, product assembly, and multiple transportation steps in between. Waste generate...
Waste management can be grouped into a small set of options, which are reuse, recycling, thermal destruction, and disposal. Reusing the entire plastic-containing product or at least some of its components is environmentally desirable, but plagued by all kinds of challenges (Geyer and Jackson 2004). The environmental advantage is that not only the m...

26. Sept. 2024 · Starting with celluloid in 1869, this transformative substance has evolved from a simple ivory substitute to a cornerstone of modern manufacturing. This article travels through time to chart this evolution and the profound impact of plastic on today's world.
16. Mai 2014 · But the big breakthrough - arguably the birth of the modern plastics era - came in 1907, with the invention of Bakelite by the Belgian-born American Leo Baekeland.
