Plastics are a wide range of synthetic or semi-synthetic materials, that usually use a polymers as a main ingredient. The plasticity during production makes it possible for plastic to be moulded, extruded or pressed into solid objects of various shapes, making them an adaptable material for many different uses. This adaptability, plus a wide range of beneficial properties, such as being light weight, durable and flexible, alongside cheap production processes has led to widespread adoption in contemporary society. Plastics typically are made through human industrial systems; most modern plastics are derived from fossil fuel based petrochemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials such as derivatives of corn or cotton.
Plastics have many uses throughout society. In developed economies, about a third of plastic is used in packaging and roughly the same in buildings in applications such as piping, plumbing or vinyl siding. Other uses include automobiles (up to 20% plastic ), furniture, and toys. In the developing world, the applications of plastic may differ, 42% of India’s consumption is used in packaging. For example, in the medical field as well, with the introduction of polymer implants and other medical devices derived at least partially from plastic. Worldwide, about 50 kg of plastic is produced annually per person, with production doubling every ten years.
