Kissinger-Kai (K-K) model-free method was coupled with Particle Swarm Optimization (PSO) model-fitting method using the thermogravimetric experimental data. A global sensitivity analysis was carried out using Latin Hypercube Sampling and rank transformation to assess the extent of impact of the input kinetic parameters on the output results. Furthermore, a thermodynamic analysis was performed to obtain parameters such as enthalpy change (�H), Gibb's free energy (�G), and entropy change (�S). The activation energy (EA) of the microalgae Chlorella vulgaris and HDPE binary mixture were found to be lower upon the addition of catalysts. Among the catalyst used, bi-functional LS/HZSM-5 catalyst exhibited the lowest EA (83.59 kJ/mol) and �H (78 kJ/mol) as compared to LS and HZSM-5 catalysts. © 2021 Elsevier Ltd publisher: Elsevier Ltd date: 2021 type: Article type: PeerReviewed identifier: Majid, M. and Chin, B.L.F. and Jawad, Z.A. and Chai, Y.H. and Lam, M.K. and Yusup, S. and Cheah, K.W.
