| Abstract: | The rapid accumulation of post‐consumer plastic waste, particularly polypropylene‐based waste face masks (FMW), alongside underutilized agro‐industrial residues such as Moringa oleifera (MO) seedcake, presents a significant environmental challenge and an opportunity for thermochemical valorization. This study presents a non‐isothermal thermogravimetric investigation of the pyrolysis and co‐pyrolysis behavior of MO, FMW, and their 1:1 mass blend under nitrogen atmosphere at heating rates of 5°C, 10°C, and 15°C min−1 over a temperature range of 30°C–700°C. Model‐free iso‐conversional kinetic approaches (KAS, OFW, Friedman, and Starink) along with the Kissinger method were employed to evaluate the apparent activation energy (Ea) and pre‐exponential factor (A) as functions of conversion. The co‐pyrolysis system exhibited a statistically significant reduction in activation energy relative to mass‐weighted predictions, confirming synergistic kinetic interactions between the lignocellulosic biomass and polypropylene matrix. The thermodynamic parameters (ΔH, ΔS, ΔG), derived consistently from the kinetic data, indicated that pyrolysis and co‐pyrolysis were endothermic and non‐spontaneous processes, requiring continuous external energy input. Nevertheless, the MO–FMW blend showed lower Gibbs free energy barriers than individual feedstocks, reflecting reduced thermodynamic resistance during decomposition. This study established a foundational kinetic–thermodynamic framework for MO–FMW co‐pyrolysis and provided the essential parameters for reactor design and subsequent product‐oriented pyrolysis studies.
