Abstract
Humans who were born and live in this modern era, of course, are no strangers to plastic. Plastic seems to have become a part of human life and is every where. If we pull it back, the initial appearance of plastic was one of the technological inventions by humans who were 'sophisticated'. Before there were plastics, humans depended on natural materials, such as wood fiber and ivory. Scientists are starting to worry that if this material from nature continues to be exploited, it will run out over time. They are competing to find alternative artificial materials that can replace various mass needs taken from nature.The names of scientists such as Alexander Parkes, Charles Goodyear, Charles Schonbein, to Dupont, Wallace Carruthers, discovered the starting material for making plastic. Only in 1962 until now, types of plastic such as PVC, HDPE, to bioplastics, have appeared. All these plastics were originally made to facilitate human activities, such as in the health industry, where many medical aids are made of plastic. As technology develops, other industries are starting to look at plastic as a raw material for their production. Today, more and more things are made of plastic. Call it cutlery, electronic support, furniture to fashion. Because of this development, the amount of plastic production has increased drastically but plastic recycling has not been effective. Moreover, there are still many people who choose to burn their waste, including plastic
