  • Hello there - You see me on the streets in your neighborhood all the time - I'm a garbage truck,

  • although some folks like to call me a refuse truck or recycling truck. You know, people sure make a lot

  • of waste - each person in America makes more than four pounds of garbage every day - that's over

  • fourteen-hundred pounds a year - wow! My job is to collect that waste and try to recycle as much as I

  • can back into use. Whatever is left has to be safely disposed of. How do I work? Here - let's take a

  • look...

  • While there's different kinds of garbage trucks - like front-loaders and rear-loaders, I'm a side-loader,

  • so we'll look at how I'm put together. One thing's for sure - we're all big, strong, and tough.

  • Behind the cab, where the driver sits - is the hopper, where the trash is tossed in. A large mechanical

  • arm grabs the bin, pulls it up and tips it so the trash falls into the hopper. Below that is a packing blade

  • that pushes and makes the garbage smaller in size. The blade moves the trash toward the back of the

  • truck, where it curves around and fills up the holding area. When the truck is all filled up, an ejection

  • blade pushes the compacted trash out of the back of the truck at the dump and it's ready to start all over

  • again.

  • And what happens to all that trash? Well, paper and some other materials are safely burned - often to

  • produce steam that runs turbines to make electricity that people can use. Food, wood, and other trash

  • that is what they call "organic," are taken to compost centers, where they break down and decompose

  • into fertilizer. Other trash, like metals, plastics, and glass, is sent to recycling centers, where it's cleaned

  • and processed into metal, plastic, and glass that can be used again.

  • Unfortunately, more than half of the garbage that's created cannot be burned, composted, or recycled -

  • so it has to be taken to a landfill. A landfill is a large area where trash can be safely buried and kept so

  • that it doesn't contaminate our drinking water and other natural resources. Of course, there's only so

  • much land in our world, so recycling and composting has to go up, and use of landfills has to go down -

  • way down.

  • So the next time you see me, the garbage truck - be sure to wave and say "Hi," because we're all

  • working together to make our world a better place to live and play - Take care and "Ta-ta!"
