Thermogravimetric and mass spectrometric (TG-MS) experiments were carried out using textile dyeing sludge (TDS), sugarcane bagasse (SB) and their blends with different ratios. (Co-)combustion kinetic parameters of each sample were calculate by using TG-derivative curves. CO2, NOx, NH3 and SO2 emissions were also quantified. The addition of SB to TDS lowered SO2 but enhanced NOx, NH3 and CO2 emissions. Calculated activation energies (E) of the pure TDS and SB, and their blend (TB64) according to the Flynn-Wall-Ozawa method were on average in the range of 185.6-253.9 kJ.mol(-1), 152.9-235.9 kJ.mol(-1) and 111.1-161.8 kJ.mol(-1), respectively. Based on the Kissinger-Akahira-Sunose method, E estimates of the pure TDS and SB, and the blend ranged from 183.1 to 251.0 kJ.mol(-1), 152.1 to 237.2 kJ.mol(-1) and 108.2 to 160.1 kJ.mol(-1), respectively. Our results indicated that the blend E was affected by the interactions between TDS and SB. (C) 2017 Elsevier Ltd. All rights reserved.
