What is recycling?

Recycling is a way to take trash and turn it into new products. There are a number of different recycling processes that allow materials to be used more than once.

What can be recycled?

All sorts of materials can be recycled. Some of the most common processes in use today involve recycling plastic, glass, metals, paper, electronics, and textiles. Typical used items made of these materials include soda cans, plastic milk cartons, newspapers, old computers, and cardboard boxes.

How does recycling work?

Recycling is actually a complicated process and is different for each type of material.

Aluminum cans - Aluminum cans were one of the first items to be heavily recycled. The process isn't quite as complicated as it is for some other materials. The cans are first shredded and then melted. From there, the aluminum can be used to make new cans and other aluminum items.

Plastic bottles - There are a lot of types of plastics and each type is made from a different combination of chemicals. As a result, plastic bottles are first sorted into their various chemical types. Then they are cleaned to get rid of any leftover food or other waste. Next, the bottles are crushed or shredded into fine plastic chips. Then the chips can be melted down to create new plastic or turned into a fiber used for making carpets or clothing.

Paper - Paper starts its recycling process by being mixed with water and other chemicals to break it down. It then gets shredded and heated up. This process eventually turns the paper into a pulp or slurry. The pulp gets strained in order to remove any glues or plastics. After that, it gets cleaned and bleached to remove any left over inks or dyes. Now the pulp is ready to be made into new paper.

Computers and Batteries - Computers and batteries are usually recycled in order to remove harmful chemicals as well as to recover, or salvage, some valuable materials such as gold from electronics boards.

The Recycling Loop

The recycling symbol, or loop, has three arrows. Each arrow represents a different step in the recycling process. These steps are:
  1. Collecting recyclable materials, like aluminum cans and plastic bottles.
  2. Processing the old materials and making new items.
  3. Buying items made from recycled materials

Benefits of Recycling

There are a number of benefits from recycling. These include: What can you do?

Be sure to recycle everything you can in your house and school. There is almost always a "recycle" trash can around. Be sure to drop your used aluminum cans and plastic bottles there. At home, be sure to put paper items like the newspaper, cereal boxes, and homework pages into the recycle bin.
