NASA's Technology Transfer Office (TTO) at Stennis Space Center worked with a small tire recycling company, Cryopolymers, Inc. in St. Francisville, La., to improve its process for recycling used tires. Stennis helped Cryopolymers make better use of the cryogens, or super-cold fluids, used in its recycling process. First, the tires are frozen, then broken down and made into a material called "crumb," which can be used in asphalt road beds, agricultural hoses, and truck bed liners. TTO based this assistance on NASA's experience using cryogens in the testing of Space Shuttle Main Engines.
