Recycled Products From Scrap Tires

Products which are salable in the world marlet

The scientist who developed the“Patent Protected Process” of Pyrolysis and Enhancement which will be utilized by Brittney Recyclers, has over 40 years in polymer development and manufacturing. He has a PhD. in chemical engineering and a lifetime of achievements in developing and building plants for new chemical processes.

The Process

A brief overview of the process is as follows. Whole or scrap tires are received at the pyrolysis plant. Tires are shredded into 1 inch by 2 inch pieces. These small pieces are transported on a series of conveyor belts that are magnetically charged to remove excess steel particles.

After the loose steel has been removed, the small chunks are conveyed into the processing vessel through a series of airlocks and are depolymerized by heating them in the absence of oxygen.

The highly controlled and computer regulated process involves, simultaneously, a solid phase reaction, and a vapor phase reaction (thermal cracking). This results in a hydrocarbon vapor and un-milled carbon black.

The carbon black is milled to produce carbon black particles of selected particle size. The milled carbon black is then screened to remove contaminants. This refined carbon black product has been examined under a scanning electron microscope at a magnification of one million times. No structural differences from virgin carbon black could be determined.

The vapor or gas produced in the process is passed through a cyclone and bag filter. The lighter hydrocarbons are utilized as fuel for plant operations, and the heavier hydrocarbons are condensed into a liquid that is marketed as specialized premium grade chemical processing oil referred to as extender oil or plasticizer oil. The refining processes use equipment and materials that have been long employed in the cosmetics and refining businesses.

Demand for our products is currently strong because of increased requirements by manufacturers to incorporate the use of ‘recycled materials’. The annual domestic market for carbon black is approximately 4.0 billion pounds of which 2.0 billion pounds is for high quality N326 grade blacks. Our process will produce carbon black which when tested meets the specifications for N326.

For every six pounds of carbon black used in plastics or rubber compounding, a gallon of plasticizer oil is required. Annual U. S. production of plasticizer oil is 300 million gallons. The process will produce plasticizer oil with properties of ASTM 104A solvent oil.

The Toner Black Process consists of three successive processing steps:

  • Removal of sulfur from the Carbon Black
  • Removal of zinc oxide and other metal oxides
  • Blending or compounding of purified carbon black with the binder resin, a charge control agent, flow control agents, and magnetite (black iron oxide) to produce: FINISHED TONER BLACK
