Pyrolysis Defined Definition of Pyrolysis Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen  The word is coined from the Greek-derived elements pyro "fire" and lysis "separating". IT IS NOT INCINERATION OR COMBUSTION OF WASTE MATERIAL

GICC TIRE PYROLYSIS PROCESS Two Processes DCS Thermal Engine Waste wood chips are fed into the DCS Thermal Engine to create heat for the process using a proprietary technology. The technology was first created in Italy, and Seven Islands Environmental Solutions is the first company to use it in the US. The exhaust gas from the DCS passes through a titanium catalyst bed housed in the Catalyst Box (C.I.T. Cube) where air pollutants are treated prior to passing through the pyrolysis unit

GICC TIRE PYROLYSIS PROCESS (continued) Pyrolysis Unit (PDG) The pre-shredded tire chips are conveyed to and pass through the PDG in tubes heated from the gases surrounding the tubes from DCS. The heat breaks down the tires into their original components Synthesis Oil Recovered Carbon Black Synthesis Gas Steel

GICC TIRE PYROLYSIS PROCESS (continued) Original components are separated and stored for shipping and re-use Excess Syngas is diverted from the safety flare back into a burner box connected to the PDG. The gas is burned for process heat and the exhaust flows through the catalyst box and into the PDG. It replaces the DCS as a heat source once the process is started, making the process self-sustaining as long as the tire chips continue to be prolysized.

GICC TIRE PYROLYSIS PROCES(continued) A proprietary Hydraulic Water Filter filters particles from the exhaust air stream which results in clean emissions. An Exhaust Stack removes heat and water vapor from the system The Existing GICC Plant daily removes the equivalent of 5 tons per day of tires from landfills and waterways. The existing plant was designed, built, shipped, sited, constructed and operational two years from the date the final decision was made by Cox to proceed!

Future Seven Islands Environmental Solutions (SIES) is working on research to be able to process other feedstocks with this technology. SIES is fine tuning the operational capabilities of the existing 5 ton per day plant. Plans include a larger capacity plant in the years to come.
