Unlike glass, which is made entirely of natural substances—minerals--plastic is composed of man-made and raw materials, including petroleum and crude oil. Here’s how plastic is recycled.
•People bring their used plastics to a recycling center.
•The plastic is brought to a recycling plant where it is washed and inspected.
•The recyclable plastic is washed and chopped into tiny flakes.
•The flakes are separated in a flotation tank.
•The flakes are dried and then melted into a liquid.
•The liquid is fed through a screen for even more cleaning. It comes out in long strands.
•The strands are cooled and cut into pellets.
•The pellets then make their way to manufacturers who use them to make new products
