Earth Day Activities: Environmental Uses of Phone Books

Earth Day and Phone Book Activities

Earth Day and Phone Book Activities

Ever wonder what to do with all those old phone books?

Earth Day is coming and a good earth day activity is to develop creative uses for these phone books, beyond just recycling or throwing them in the garbage.

Phone books have a myriad of uses such as shredding the pages for use as packing material, compost materials, and booster seats.

Phone Book Facts

Despite the increase of Internet based telephone number directories, the production of phone books is increasing.

Here are some facts to get you thinking about how important it is to recycle or reuse your phone books.

  • On average, over 600,000 tons of phone books end up in landfills every year.
  • There are enough phone books created each year to measure 106,700 miles when lined up end to end. This means they would circle around the earth about 4.28 times!
  • About 80 percent of all U.S. paper mills use some recycled material in their manufacturing service. It is estimated that about 200 mills use ONLY recycled material.
  • There are more than 7,000 different titles of yellow pages.
  • 540 million telephone directories are distributed each year.

Earth Day Activities

Now that you see the current phone book dilemma, a good earth day activity is to find creative uses for all these unwanted phone books.

If just 500 phone books can be kept out of a land fill we could save between 17 and 31 trees, 7,000 gallons of water, 463 gallons of oil, 587 pounds of air pollution, 3.06 cubic yards of landfill space and 4,077 kilowatt hours of energy according to the American Forest & Paper Association.

Example Activities include:

  • Earthworm Bedding - shred the white pages and combine them with dirt, which enriches the soil as the pages decompose to support the earthworm habitat. Do not use the yellow pages, because of the chemicals.
  • Mulch - tear the pages out a phone book and lay them about 6 - 8 pages thick on top of the soil in a flower garden or among shrubs. Then cover the pages with a thin layer mulch. The pages will act as shield to prevent grass from growing through the mulch. Also the phone book pages will decompose and enrich the soil over time.
  • Booster Seat - use fabric to cover phone books, sealing the seams with fabric glue or needle and thread. This keeps the phone books from sliding around as kids wiggle around on them.
  • Packing Material - shred phone book pages for use in packaging instead of using packing peanuts. Shredded phone book pages are biodegradable and packing peanuts are not.

Your Turn - Share your ideas for additional uses of these relics of the past.

Are you searching for interactive graphics for use in science class to show your students the current and expected effects of global warming?

The Climate Time Machine by the Jet Propulsion Laboratory (JPL) and California Institute of Technology (CIT) of NASA provides the graphics you need.

These graphics are also excellent for displaying on an interactive white board (IWB) to allow you and your students to interact with the data provided by the graphics representing climate change .

Climate Change

The Climate Time Machine provides information in the following four categories:

Sea Level: recent satellite observations have detected a thinning of parts of the Greenland ice sheet at lower elevations.  A partial melting of this ice sheet would cause a 1-meter (3-foot) rise.  If melted completely, the Greenland ice sheet contains enough water to raise sea level by 5-7 meters (16-23 feet). This visualization shows the effect on coastal regions for each meter of sea level rise, up to 6 meters (19.7 feet).

Sea Ice: this visualization shows the annual Arctic sea ice minimum from 1979 to 2007.  At the end of each summer, the sea ice cover reaches its minimum extent, leaving what is called the perennial ice cover. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979.

CO2 Emissions: this visualization shows the amount of annual carbon dioxide emissions produced by the top 12 nations or regions from 1980-2004.

Average Global Temperature: this color-coded map shows a progression of changing global surface temperatures from 1885 to 2007.
