The publication presents the results of thermal examinations conducted to determine of the thermal degradation of the polymeric binder (BioCo2) in the moulding sand. Thermal degradation process was identified using literature data on the decomposition of the polymers materials and based on own research (TG-DSC, MIR-DRS). In order to determine the degradation temperature and the thermal effects of transformations occurring when the moulding sand were heated, two methods were used: the thermogravimetry (TG) and differential scanning calorimetry (DSC). In this paper the spectroscopic studies (MIR-DRS) were also performed in order to elucidate structural changes occurring in the BioCo2 binder under an influence of heating. Temperature spectra were made for the moulding sand sample in the temperature range: 25-400^oC (operation range of the temperature attachment of the IR spectrometer). The heating process was performed in a continuous way, and the spectra were recorded at a given temperature. On the bases of the performed thermal analysis of the moulding sand the temperature range required for the efficient thermal reclamation was indicated.
