A Look at the Recycling Process
Did you ever wonder what happens to the objects that you toss into recycling bins? Here’s a look at how glass, plastic, aluminum and paper are recycled.
People have been using and reusing glass for thousands of years. As long as 3,000 years ago, Egyptians used glass to make jewelry, cups and other items. Glass is made of sand, soda ash and limestone and is one of the easiest materials to recycle. Here’s how it works.
•People bring their glass to recycling centers.
•The glass is sorted by color at these centers.
•The glass is transported to a processing facility where it is cleaned and crushed into what is called cullet.
•The cullet is brought to a manufacturing plant and mixed with more sand, soda ash and limestone.
•The mixture is heated in a furnace and turned into a liquid.
•The liquid is then poured into molds and shaped into new products.
