The aim of this study was to investigate the bioenergy potential of greenhouse vegetable wastes like tomato, pepper, and eggplant wastes individually, in equal-mass binary mixtures, and in equal-mass ternary mixtures under pyrolysis conditions using thermogravimetric analysis (TGA). The TGA experiments were carried out in a nitrogen gas flow rate of 100 ml min−1, at heating rates of 10, 20, and 30 °C min−1, and temperature range of 850 °C–900 °C. For the seven biomass samples activation energy (Ea) and thermodynamic parameters were determined using the Flynn–Wall–Ozawa, Kissinger–Akahira–Sunose, and STR kinetic models. It was observed that the decomposition temperature of biomass samples during pyrolysis or co-pyrolysis ranged between 125 and 695 °C, and the corresponding mass loss was significantly high, ranging from 59% to 78.2%. In terms of Ea, tomato waste as a single biomass (83.67–89.21 kJ mol−1), and in binary mixtures with pepper (69.41–75.68 kJ mol−1) and eggplant (71.41–77.65 kJ mol−1), was found to be a competitively viable biomass source compared to other biomasses studied in this work and in the literature. In the study, the ΔH (change in enthalpy) value for the pyrolysis reaction of tomato was calculated to be between 78.49 and 84.03 kJ mol−1, while the ΔH values for the co-pyrolysis reactions of tomato-pepper and tomato-eggplant were calculated to be between 64.37–70.64 kJ mol−1 and 66.39–72.63 kJ mol−1, respectively. It was determined that the tomato, tomato-pepper, and tomato-eggplant samples were more competitive compared to the other samples in terms of the energy requirements of the pyrolysis or co-pyrolysis reactions.
