Trash Talk Tuesday presents: "What's in a Landfill?"
Connect the items with the correct percentages of landfill composition.
a. Disposable Diapers 1. 12 percent
b. Paper 2. 7 percent
c. Food and Yard Waste 3. > 40 percent
d. Building Materials 4. < 2 percent
e. Polystyrene Peanuts 5. 1 percent
a: 4, b: 3, c: 2, d: 1, e: 5.
In the popular imagination, great massifs of foul, never-biode-grading disposable dipes fill our dumps, blotting out the sun and staining our posterity. In fact they make a nearly negligible contribution to the landfill's mass. Same goes for those pernicious poly peanuts.
You'd think that food waste and yard waste were landfill ephemera-substances that quickly break down and return to nature. But excavations reveal that even after the passage of decades, they are still recognizably themselves.
Building waste: shattered cinder blocks, shivered timbers, concrete crusts sprouting skeins of twisted rebar, drywall in torment, pot metal and plastic locked in a death embrace. Not easy or simple to recycle.
In 1970 15 percent of all US wastepaper was recycled; in 2005 more than 50 percent. But "all US wastepaper" meant 6 million tons in 1970; in 2005 it meant 84 million tons.
