Every year, some 540 million unsolicited phone books arrive on America’s doorsteps. Phone books simultaneously account for about 660,000 tons of trash annually. Meanwhile, many people find it easier and more convenient to use the Internet to look up telephone numbers. Going paperless not only cuts down on directory clutter, it decreases pollution and saves trees.

For those who still look up phone numbers the old-fashioned way, it’s easy to recycle old books in city curbside recycling bins. Find out which cities do that at Earth911.com.
