We've all heard the old adage, "One man's trash is another man's treasure." Waste Management Inc. actually proved it with a study a couple of years ago that found the materials in U.S. landfills alone holds about $10 billion in value every year. North America's leading provider of comprehensive waste management solutions knows that we are a throw-away society and has perfected getting garbage to the landfills. Its challenge now is to get people to understand that realizing a zero-waste operation is an achievable goal and that there is value to the trash being thrown out, if we all just change our perspectives.
