The results of the thermal reclamation investigations of the spent moulding sand with the polymer BioCo2 binder, are presented in the paper. The reclamation process of the quartz matrix was carried out on the basis of the author's own method of selecting the reclamation temperature. On the bases of the performed thermo-gravimetric analysis of the binder the temperature range required for the efficient thermal reclamation was indicated. In order to confirm the assumption the thermal reclamations were performed at a temperature determined by the TG and - for comparisons - at a lower and higher temperature. During the reclamation process samples of the reclaim were taken for testing ignition losses in order to determine the process efficiency. The correctness of the assumed method of selecting the temperature range of the thermal reclamation of spent moulding sand with the polymer BioCo2 binder was confirmed.
