Plastics are versatile materials. They are lightweight, durable, corrosion-resistant and ideal for thermal insulation and electrical insulation. They are cheap to manufacture, and the production volume is huge. The world uses more than 260 million metric tons of plastics every year, accounting for 8% of the global output of crude oil. The phenomenal increase in the volume of plastics manufactured during the past few decades has completely changed our lifestyles. However, the consumption and ultimate disposal of waste plastics have created significant effects on the ecosystem and the environment.
