The growing amounts of plastic and biomass wastes have become a global problem challenging the environmental sustainability. In this regard, waste to energy technologies has gained more importance to convert waste inventory into useful energy and value added products. In this study, pyrolysis characteristics of a textile industry waste (recycled polyester fabric, RPF) and an agricultural waste (olive residue, OR) and their (1/1 wt.%) blend are investigated via thermo-gravimetric analysis (TGA) method. Thermal degradation were examined at heating rates of 10, 30 and 50°C min-1 heated to 1000C with 100 mL min-1 flow of nitrogen. Kinetic analysis of pyrolysis has been performed with Flynn-Wall-Ozawa (FWO) method. Experimental and theoretical TGA profiles compared and some synergistic interactions have obtained during co-pyrolysis. The activation energies are determined as 254.22, 203.22, 231.72 kJmol-1 for RPF, OR and RPF/OR blend, respectively. The results of kinetics analysis and evaluation of the thermodynamic parameters (activation energy, enthalpy, Gibb’s free energy and entropy) have shown that co-pyrolysis of OR and RPF is promising alternative for sustainable bioenergy production.
