Waste Management World Discusses JBI Progress

Canadian Plastic to Oil Company Tests New York Facility

13 December 2011

Ontario based Canadian waste plastics to oil specialist, JBI has successfully completed its final Plastic2Oil (P2O) Stack Test performed by environmental engineering consultants, Conestoga-Rovers and Associates (CRA) on its P2O commercial processor in Niagara Falls, New York.

According to JBI the stack test measured emissions from the processor vent and was observed by the New York Department of Environmental Conservation (NYSDEC) who were present during testing.

The company said that three stack tests were performed on the existing commercial processor with a pre-melt system.

Unwashed, unsorted waste plastics, including various industrial plastics and gas tanks from end of life vehicles, were used as feedstock for the testing. According to JBI this type of feedstock is consistent with the day to day waste plastic that the processor is currently converting into fuel.

The P2O process works by cracking plastic hydrocarbons into various shorter hydrocarbon chains which exit the reactor in a gaseous state. The company said that its proprietary catalyst and process engineering enables it to capture nearly 90% of the hydrocarbon content of difficult to recycle waste plastic.

The stack tests were conducted at feed rates of 3258 lbs/hr (1478 kg/hr), 3233 lbs/hr (1466 kg/hr) and 3932 lbs/hr (1784 kg/hr) respectively.

Ultimately, the company claimed that the test results proved that emissions decreased with increased feed rates, validating its P2O technology as a "highly green" and scalable process.

Furthermore, the company said that the addition of the pre-melt system, which was designed and installed in earlier in the year, greatly improved feed rates for the process. Draft emissions data was provided by CRA staff following the completion of each test. Emissions were said to be significantly reduced through more efficient and higher combustion of the off-gas generated by the process.

According to JBI the final average emissions for 3,923 lbs/hr were 15.97% O2, 3.05% CO2, 3.1ppm (parts per million) CO, 15.1 ppm NOx, 2.88 ppm TNMHC and 0.02ppm of SO2. The NOx emission was approximately one-fifth that of the original P2O processor tested 1 year ago.

The company added that the P2O processor did not have any stack filters or scrubbers and 'In-spec' end-user fuels produced were also tested and verified as ultra-low sulphur.

JBI said that it anticipates receiving final reports from CRA after audit and peer reviews of the testing are concluded. These reports and permit modifications, which allow a higher feed rate, will be filed in accordance with NYSDEC permit regulations.

The company said that it believes the successful stack test results will aid significantly when seeking permit exemptions in other U.S. states, and that the results will contribute to maximising production at the existing New York processing plant.
