| Summary: | Brazilian production of PET (polyethylene terephthalate) in 2010 was of 505,000 tones. The PET waste may
be used to generate energy by controlled burning. In this study, emissions of light hydrocarbons generated during
combustion of these wastes are characterized. Samples of post-consumer PET bottles were inserted in an electric furnace
at temperatures of 600, 800 and 1000°C under an atmosphere of 15% O2 and 85% N2. The effluents were subjected to
a SiC filter and channeled into the second furnace at 1000°C. Stainless steel meshes were placed in the second furnace in
order to work as catalyst. Gas chromatography is used to evaluate the effluent with and without the catalyst use, wherein
is showed a significant reduction in the emissions using the meshes. Results allow a characterization of the hydrocarbons
generated during the controlled burning of PET waste providing information for control and recovery of these gases
