How Recycling Works

Every week, millions of plastic bottles are thrown into recycling bins. But what happens next? The journey of a single bottle has four main steps, and it begins right outside your door.

First, the bottles are collected by special trucks and taken to a recycling center. There, workers and machines sort the materials: glass goes one way, metal goes another, and plastic is separated by color and type. Sorting matters, because different plastics must be treated in different ways. Glass bottles can be recycled again and again without losing quality, and metal cans are valuable because making new metal costs a lot of energy.

Next, the plastic bottles are washed and cut into tiny pieces. These pieces are melted and turned into small pellets. The pellets are sold to factories, where they are made into new products — carpets, bags, park benches, and even jackets. One jacket, for example, can be made from about twenty-five old bottles.

Finally, the new products are sent to stores, and the circle begins again. Recycling is not perfect: dirty plastic often cannot be used, and some materials are recycled only once. But recycling reduces waste and saves energy, and every clean bottle you sort keeps plastic out of rivers and seas. Workers at the center say the system works best when families help at home: rinse the bottle, check your town's rules, and never put plastic bags in the recycling bin.
