The National Institute of Standards and Technology (NIST) evaluated the process and concluded that "the process could have significant commercial potential; the process will have wide commercial appeal. There would be a ready demand for the full range of products that could be manufactured without having to do extensive market development work, and the market is easily large enough to absorb all the products that can be made by this process.” They also concluded, "If successful, the energy impact of the invention would be significant. It would make possible converting millions of scrap tires into useful fuels and highway paving compounds that would have a higher value to society than burning the tires. The fuels and highway paving compounds produced would displace the crude oil currently used to produce these fuels and compounds. Reclaiming about a billion barrels of used motor oil that is presently not reclaimed would have a significant energy impact.”
THE SENERGY S.T.O.P. Process was developed by Amoco Corporation and the University of Wyoming. Based on research at the University, three patents were issued to Amoco and the University.
The process involves a two-stage reactor conversion of waste motor oil and tires at moderate temperatures. The oil product of the process is commercial fuel oil. The carbon black can be used as modifier filler for paving grade asphalt, construction sealant and plastic resins. Further uses are colorants for construction materials such as concrete; and with recent development, can be used as a feedstock for an activated carbon product.
The University has reassigned the three process patents to SENERGY, LLC which was formed to commercialize Scrap Tire/Waste Oil Processing (STOP) technology.
