Abstract In this study, multi‐heating rate and multi‐temperature pyrolysis experiments of mechanically and biologically treated Australian biosolids is conducted in a Thermogravimetric Analyser (TGA). A hybrid approach is applied for the estimation of kinetic parameters of biosolids pyrolysis where model‐free methods such as KissingerAkahiraSunose (KAS) and OzawaFlynnWall (OFW) are used to derive activation energy while model‐fitting method such as Coats‐Redfern is used to derive pre‐exponential factor. The results obtained from this study are compared with other biosolids, lignocellulosic biomass, microalgae and coal. The activation energy and pre‐exponential factor obtained in the current work are 99.75 kJ/mol and 1.7×109 min−1 respectively. The coefficients of determination (R2) obtained in the determination of activation energies ranged between 0.93 and 0.99.
