"In 1998, the U.S. EPA estimated that 136 million tons of building-related waste is generated in the U.S. annually, which is 25% to 40% of the national solid waste stream. A 2003 update shows an increase to 164,000 million tons annually, of which 9% is construction waste, 38% is renovation waste, and 53% is demolition debris." (Quoted from article)
