One of methods of the waste neutralization is their thermal transformation in suitable installations or devices in order to achieve the state, which is no longer dangerous for the human health and life or for the environment. In effect of the thermal transformation the “new” wastes are created, which, by law are suppose a to be utilized first. These wastes may be utilized if their properties are suitable. In the paper, the process of thermal utilization of hazardous and municipal wastes is presented, together with the investigation results of the grain composition, surface area, density and of the initial chemical analysis of the created ashes. The research of the grain composition was conducted by using the “Fritsch” apparatus. On the base of the grain composition, the surface area of ashes under investigation was determined, whereas the density was determined by using the helium pycnometer. The purpose of the research was to determine how the properties of ashes are changed and if the differences allow to use these ashes in future.
