Glass

GLASS RECYCLING  ﻿   Glass never wears out -- it can be recycled forever.Glass is made of sand, soda ash and limestone. We save over a ton of resources for every ton of glass recycled -- 1,330 pounds of sand, 433 pounds of soda ash, 433 pounds of limestone, and 151 pounds of feldspar. A ton of glass produced from raw materials created 384 pounds of mining waste. Using 50% recycled glass cuts it by about 75%.

** Experimental Design **
 * Explain how glass is made initially, not the recycling process
 * Explain the process of recycling glass starting with how the glass is separated and why
 * Explain why recylcing glass is more beneficial than throwing it away
 * List at least 3 ways recycling glass has improved our environment

Example

Facts about glass recycling in 1994:


 * Glass containers saves 9 gallons of fuel (oil) for every ton of recycled glass. Glass containers used for new glass containers, fiberglass insulation, road beds (aggregate), concrete block, glassphalt (asphalt) (Source: Waste Management, Inc.)
 * Recycling one glass bottle saves enough electricity to light a 100 watt bulb for four hours. (Source: Recycling and Buy Recycled Fact Sheets America Recycles Day)
 * If all the glass bottles and jars collected through recycling in the U.S. in 94 were laid end to end, they'd reach the moon and half way back to earth. (Source: American Flint Glass Workers Union)
