Summary/Abstract: The use of paper and cardboard as packaging and stationery materials is due to their availability, low cost, and recyclability. From a chemical point of view, paper and cardboard are lignocellulosic materials, and their thermal properties are dependent on the chemical composition, which may differ depending on the manufacturing process. Thus, we investigated to what extent the presence of additives and/or the proportion of the three main components (cellulose, hemicellulose and lignin) in cardboard and cardboard products available on the market (IKEA paper, white matte cardboard and colored matte cardboard) influences the thermal properties. The samples were analyzed by microscale combustion calorimetry (MCC). MCC tests revealed improvements in thermal properties in the case of white matte cardboard due to the TiO2 content which exhibits a synergistic effect. The total heat release, THR, decreased from 11.07 (kJ/g) for IKEA paper to 8.01 (kJ/g) for white matte cardboard.
