Assessment of the thermal pyrolysis characteristics and kinetic parameters of spent coffee waste: a TGA-MS study

The present study aimed to investigate the pyrolysis characteristics and kinetics of spent coffee waste (SCW) at different heating rates (5–40 °C/min) at a temperature ranging from 30 to 800°C in a thermogravimetric analyzer (TGA). First, the physicochemical properties of the SCW were characterized using X-ray diffraction, Fourier transform infrared spectrometry, scanning electron microscopy, and elemental analysis. Then, the thermal...
