Parkesine, the first member of the Celluloid class of compounds and considered the first man-made plastic, is patented by Alexander Parkes. [4] 1869: John Wesley Hyatt discovers a method to simplify the production of celluloid, making industrial production possible. 1872: PVC was accidentally synthesized in 1872 by German chemist Eugen Baumann ...
Global Plastic Production (1950-2022) [2] Plastics production has been growing globally. The numbers include thermoplastics and polyurethanes, as well as thermosets, adhesives, coatings, sealants, and PP-fibers. [1] Data was gathered by PlasticsEurope (PEMRG) and Consultic, or the nova-institute. [3] [4]
Between 1950 and 2017, 9.2 billion tonnes of plastic are estimated to have been made, with more than half this having been produced since 2004. Since the birth of the plastic industry in the 1950s, global production has increased enormously, reaching 400 million tonnes a year in 2021; this is up from 381 million metric tonnes in 2015 (excluding ...
There are differing estimates of how much plastic waste has been produced in the last century. By one estimate, one billion tons of plastic waste have been discarded since the 1950s. [32] Others estimate a cumulative human production of 8.3 billion tons of plastic, of which 6.3 billion tons is waste, with only 9% getting recycled. [33] [34] [35]
In 2006 80% of the area covered by plastic mulch is found in China where it has a growth rate of 25% per year; this is the highest in the world. [4] Since its introduction in the 1950s, plastic film has been designed and developed to increase produce yield, increase produce size and shorten growth time.

From the start of plastic production through to 2015, the world produced around 6.3 billion tonnes of plastic waste, only 9% of which has been recycled and only ~1% has been recycled more than once. [6] Of the remaining waste, 12% was incinerated and 79% was either sent to landfills or lost to the environment as pollution. [6]
Its high flammability was legendary since it self-ignites when exposed to temperatures over 150 °C in front of a hot movie-projector beam. While celluloid film was standard for 35mm theatrical productions until around 1950, motion-picture film for amateur use, such as 16mm and 8mm film, were on acetate "safety base", at least in the US.
