Feedstock Tested

The technology has been under development for over 40 years, beginning with the work of Carl M. (Mike) Wilwerding, a process chemist, who invented and built small scale prototypes to demonstrate new concepts in the carbon distillation of solids.  Starting in 2004, the economics of the process pushed for  larger scale development resulting in several commercial scale operations.  These upscale machines successfully processed significant quantities of various feedstock materials.  Scrap tires is the largest volume of material tested with 1.5 million pounds processed (equivalent to 75,000 passenger tires).  Other feedstock material tested include coal, Athabasca oil sand, shale rock, plastics, biomass (corn and woodchips) and medical waste.  An early prototype of the technology processed auto-fluff which is a by-product of automobile recycling: observed and reported by the US EPA in 1988.


Tires - 1.5 million lbs
Highly aromatic oil and dry carbon black (45% solvent, 45% carbon black, 10% produced gas)

Coal - 50,000 lbs
1 ton of coal averaged 1.5 bbl.'s of fuel oil, the reusable processed coal has higher BTU value and all greenhouse hydrocarbons were removed

Oil Sands
1 ton of oil sands yielded  .85 barrels of light crude (25° API / -36C pour point) rich in aromatics.  No further upgrading required.  Minimal water, clean sand residual

Shale Rock
30,000 pounds of shale rock were provided through The US Department of Energy, Rifle Colorado Research Facility yielding 20 bbl. of high quality fuel oil

Medical Waste
processed for US Technologies in 1999. Predominately plastics producing higher ratios of process gas and oils (comparative to a #3 diesel fuel)

Grain/Corn - Biomass
Texas A & M University established a comparative with current ethanol and bio-diesel processes. The results of processing 2500 lbs showed a 15% extraction of oil and 75% recovery of solids completely in the form of a carbon black that matches the type used for the carbon filter industry
