However, plastic contains petroleum - a non-renewable resource. Thus greater the amount of petroleum burnt to create newer plastic products, the higher is the amount of greenhouse gas emission.
What is plastic recycling?
Plastic recycling refers to recovery of scrap and waste plastics. The recovered scrap plastic is reprocessed into different useful products, may be absolutely different in shape or form from the original state. Examples of recycling plastic market is soft drink bottles are melted down and cast as plastic tables and chairs.
Recyclable plastic materials include many kinds of glass, paper, metal, plastic, and polymer. The whole recycling process is shown by the example of plastic bag.
Recycling involves processing used materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production. Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, Recycle" waste hierarchy.Thus this plastic recycling process is a great boon of plastic world industry to our environment.
