Özet

The objective of this study was to investigate the effects of chemical treatment and heating rate on the emissions released from various waste wood samples including untreated pine and chemically treated MDF, plywood and particleboard after thermal treatment. Emission characteristics of the samples were determined in situ by using their FTIR spectra. Some toxic and carcinogenic gases such as formaldehyde, isocyanate, ammonia and phenyl group were detected in emissions from low temperature combustion of treated samples. For this reason, urea-formaldehyde or melamine formaldehyde treated waste wood samples should be oxidatively pyrolysed at low heating rates and low temperatures to remove nitrogen-containing toxic compounds such as ammonia and isocyanate.
