P2O Process EmissionsTo ensure that the impact of the P2O process on the environment was minimal, JBI, Inc. committed significant resources to air emissions stack testing with Conestoga-Rovers & Associates (CRA), a global environmental consulting company.
Airborne EmissionsIn December 2011, CRA completed the stack tests analyzing the emissions from the P2O process. The profile of the emissions generated by the process during the second test is shown here:
The CRA results from the stack tests completed in both September 2010 and December 2011 reaffirm other findings that the operation of the P2O processor is a clean, "green" process. Moreover, the most recent stack test from December 2011 was performed on the existing commercial processor with a pre-melt system and produced results showing emissions decreased with increased plastic feed rates; further validating that the P2O process is highly green, clean and scalable.
The emissions documented by CRA from the P2O stack test were lower than what would be produced by the same test on a natural gas furnace of similar size.
The process puts a high percentage of oxygen back into the air, with minimal harmful emissions, well within the regulatory criteria established by the New York State Department of Environmental Conservation (NYSDEC).
On December 13, 2011, JBI received an air permitting exemption by the environmental protection agency in the state where the initial RockTenn P2O site is being constructed. The environmental permit authority made the determination that this facility does not need an air permit and that the proposed project will comply with all applicable local, state and federal air pollution regulations.
Other Material ResidueAn average of 86% of the process output is usable fuel and another approx. 10-12% of the process output is off-gases.
The final approx. 2-4% is a Petcoke or Carbon Black residue (shown above right) which is below TCLP standards for safe landfill disposal. Subsequent testing also indicates this residue has a heating value of 10,600 BTU/lb, making it appropriate for use by heavy industry, such as steel manufacturers for the purposes of fueling blast furnaces.
The Company is currently seeking a BUD (Beneficial Use Determination) for the purposes of potential sale of its Petcoke residue.
