Scrap Tire Availability - USAref: 7/04 Rubber Manufacturers Association Report
  • 290 million scrap tires generated in 2003
  • In “storage”
    • Texas: 53 million abatement stalled
    • New York 40 million abatement starting
    • Colorado: 35 million no abatement
    • Michigan: 25 million abatement starting
    • Ohio: 25 million abatement in progress
    • Alabama: 20 million abatement starting
    • Connecticut 20 million no abatement
  • Total in USA: 275 million scrap tires(grossly underestimated)
  • Unused scrap tires: 57 million per year (570 thousand tons)
  • Underutilized: Fuel & Civil Engineering uses - 186 million per year (1860 thousand tons)
scrap tire utilization
Scrap Tire Utilization
  • One scrap tire is generated per year per person in the USA
    • Similar expectation in all developed countries
    • Approx. 80% of scrap tires generated annually are recovered
    • Remainder is land-filled or dumped
  • Current market for scrap tires in a shredded form (tire chips)
    • Fuel (cement kilns, stationary power plants) – Btu value similar to coal
    • Raw material for crumb rubber for finished products such as doormats
    • Embankments, playground cover
  • More shred is currently produced than is consumed
    • Shred is therefore provided at a very low price
      • Frequently given away because of the lack of market
recovery of raw materials
Recovery of Raw Materials
  • Many failed attempts over second-half 20th century
    • Incomplete process and product development
    • Low commercial development experience
    • Inability to develop customers before plant investment
    • Poor funding
  • Several efforts underway (driven by spike in fuel oil price)
  • No historical success in bringing the recovered carbon black to market
active recovery efforts
Active Recovery Efforts

Long list of failures and shuttered facilities

  • Titan Technologies, Inc. - founded in 1990; Albuquerque, New Mexico
    • Three plants in Asia are not believed to be operational due to poor economic conditions & competition for tires as a fuel source
    • Titan claims to have six plants in planning or construction; four along the US-Mexico border, one in Texas, and one in Columbus Ohio.
      • Status of these ventures is largely unknown and unverifiable
  • Earthfirst Technologies, Inc. – founded in 1997; Mobile, Alabama
    • Public Company: currently reports inability to sell the carbon black material recovered from their process
    • Licenses technology – no known sales
active recovery efforts continued
Active Recovery Efforts Continued
  • Carbon Recovery Corp., recently founded; West Berlin, New Jersey
    • Microwave technology
    • Batch Process
    • Looking for funding
  • KOUEI Industries, recently founded; Vancouver, BC, Canada
    • Batch process
  • Delta-Energy, LLC, founded 2000; Pittsburgh, Pennsylvania
    • Demonstration facility
    • Patented technology
    • Qualified customers for recovered carbon black and oil
      • Only known company to qualify carbon black for sale
    • Looking for funding
technology employed
Technology Employed
  • Titan, EarthFirst, and Delta-Energy all employ a continuous reactor operating between 800-1100 degrees F.
    • Batch processing leads to prohibitive capital requirements and product variability
    • Catalyst use lowers operating temperatures and improves efficiency
  • Most operators historically have been content to recover the oil and gas from pyrolysis of tires
    • Borderline economics that have led to many bankrupted operations
  • Newest entrants are developing technology that enables the direct recycle of recovered carbon black
    • Low manufacturing cost enables competition with products produced from oil

  • Technology has advanced sufficiently to enable economic recovery of commercially useful materials from scrap tires
  • Several developers are in the process of funding first commercial operations and looking for viable investors and operators
  • First commercial plants supplying products are expected to be in operation in 2006
