ABSTRACT

Incineration is one of the mostly used techniques for the disposal of solid wastes applied in more than 40 European countries. There are several methods used for this purpose such as fluidized bed and rotary kiln incinerators. Several types of wastes can be reduced with incineration techniques. Incineration is a significant option disposing wastewater treatment sludge. However, specific features of sludge should be considered. Most of the treatment sludge originating from municipal wastewater treatment plants includes 95–99% of water, pathogenic microorganisms, food and large amounts of organic matter. According to the content of sludge, residues and air emissions show some differences. In this study, mainly wastewater treatment sludge incineration options were investigated and compared with respect to their efficiencies and sustainability. Moreover, the end products and emissions after application of incineration options were explored and precautions or modifications that can be applied to the systems was offered.
