Recycling Old Cars

Earth and Space Science Environment Human Impacts Physical Science Air Pollution

The "cash for clunkers" program was a limited federal government program in the U.S. that gave people credits to trade in their old, gas guzzling, polluting cars for newer ones. The goal was to get older cars off the road to improve pollution. Because the “cash for clunkers” program did not allow the re-sale of old car engines, junkyards were forced to turn the cars into scrap metal. Listen to learn what this scrap metal can be turned into.
