Carbon neutrality is the balance between carbon emission and absorption from the soil, forest, and oceans. A variety of renewable energy sources, such as solar, wind, hydrogen, biomass energy, and waste energy, have been studied worldwide to achieve carbon neutrality by 2025. In particular, pyrolytic oil produced from plastic and biomass is considered a promising energy for achieving carbon neutrality because it can be effectively used not only for heat transfer but also as transport fuel. Furthermore, pyrolytic oil produced from plastics has been used as a feedstock in chemical processes to produce sustainable monomers and chemicals. However, most plants used for producing pyrolytic oil have been built in batch, not continuous manufacturing. Therefore, it is essential to scrutinize the thermal decomposition characteristics of plastics and biomass to build commercial plants. In this study, to discover the kinetic parameters and dynamic thermogravimetric characteristics, the thermal degradation of 3 types of plastics (LDPE, HDPE, PP) and sawdust was examined using a TGA under a nitrogen atmosphere of isothermal conditions in the range of 375°C, 400°C, 425°C, and 450°C. The results showed that the calculated activation energy was LDPE 136.11 kJ/mol, HDPE 181.99 kJ/mol, PP 149.39 kJ/mol, and Sawdust 34.73 kJ/mol.
