Integration of the solid waste incineration residues into dense slurry technology

The management of the residues resulted from waste thermal treatment is an integral part of waste management. Most part of this kind of residues ends in landfilling disposal. One of the major problems arise from landfilling is the contamination of the environment with harmful substances that can be transmitted by leaching. As a result of the incineration process we need to handle the resulted products as raw and fly ash. To solve this problem there were developed alternative options for the management of fly ash, such as sintering, vitrification or stabilization/solidification. This paper investigates the possibility to encapsulate the fly ash from the waste incineration process in dense slurry technology, which is used for handling of the raw and fly ash resulted from fired coal power plants. Dense slurry technology is already used in several countries in Europe and worldwide, and has proven its efficiency on the environment.
