The industrial production of poly (ethylene terephthalate), PET, continues to increase and thus it is important to understand the composition of fumes resulting from its disposal as a part of incinerated waste. In this study samples of PET material were combusted in a furnace corresponding to the German standard DIN 53,436 at temperatures of 500 degrees C, 800 degrees C (in an air flow) and also uncontrolled combustion in air. The gaseous products were then analysed using three different analytical methods: high resolution Fourier transform infrared spectroscopy (FTIR), selected ion flow tube mass spectrometry (SIFT-MS) and gas chromatography mass spectrometry (GC-MS). Carbon dioxide, methane, ethylene, acetylene, formaldehyde (methanal) and acetaldehyde (ethanal) were detected by FTIR.

Polyethylentereftalát (PET) byl spalován za kontrolovaných (800 a 500 st. C dle DIN 53436) i nekontrolovaných podmínek (pícka). Produkty spalování byly analyzovány metodou FTIR a GC-MS. Charakterizovány byly odlišnosti ve složení spalin.
