Arizona State University Research Finds Recycling Cure For Used Tires

Summary:
Imagine for a moment seeing 5 million worn tires heaped up in a pile: That is roughly the number that Arizonans produce each year–one tire for every man, woman and child. How to dispose of all those used tires without causing serious environmental hazards used to have state officials scratching their heads, but one ASU researcher believes has an answer. Civil and Environmental Engineering Assistant Professor Han Zhu says adding a small amount of the inexpensive crumb rubber to fresh concrete can improve strength and durability. Crumb rubber is the end result of grinding used tires into one-millimeter chunks. One tire produces about 10 pounds of crumb rubber and sells commercially for less than 20-cents per pound.
