Currently wastewater treatment plants are still dealing with the problem of ecological management of sewage sludge. Nowadays, thermal utilization is considered the most eco-friendly way of processing excess sludge. However, during mentioned process, fractions of ashes and dusts are generated. Such wastes, especially dusts fraction, can be potentially harmful for the environment and wastes should be stabilized before further management. In presented work, new method of stabilization of solid residues produced during sewage sludge thermal treatment is described. Laboratory and industrial scale trails were performed. Based on the results of the conducted research it can be stated that dust and ash fraction can be stabilized together without causing threat for environment. Moreover, presented method seems to be economically justified.
