The Tire Derived Aggregate (TDA) Program was established at the University at Buffalo's Center for Integrated Waste Management to help maintain a diversified and sustainable market for recycled tire products in New York State. The Tire Derived Aggregate Program operated between 2006 and 2012 to expand the beneficial use of recycled tire products in civil engineering applications around the state, in keeping with the priorities established by the New York State Tire Management Recycling Act of 2003.
Tire Derived Aggregate is a construction material produced from the estimated three hundred million tires discarded each year in the United States, twenty million of which originate in New York State. TDA consists of recycled tires processed into pieces with dimensions ranging in size from one-half inch to twelve inches.
Tire Derived Aggregate has beneficial physical properties (lightweight, low earth pressure, good drainage, and good thermal value) that make it well suited for use in civil engineering applications. Due to those beneficial properties the use of TDA in civil engineering projects has become one of the established markets for recycled tires in the United States.This website functions as a central clearinghouse of information for those in New York interested in moving forward with TDA projects. The site contains a substantial amount of information collected during the years of 2006 -2012 and will be updated in the future as possible.
