When it comes to its environmental impact, the age-old adage "One man's trash is another man's treasure" doesn't quite hold. A recent study estimated that Americans produce about 245,700 million tons of garbage per year, making the United States the No. 1 waster in the world. About 30 percent of the waste is recycled, so the vast majority is left to be either buried or burned. As a result, industry and environmental players are sparring over the effectiveness of potential trash-reducing technologies like plasma gasification, which heats trash to 5,000 degrees Fahrenheit and creates a gas that can be used to make electricity -- powering one man's wide-screen TV with another man's garbage.
