Evaluation of solid residues after incineration of waste

Popis výsledku v původním jazyce

Growing problems with the acquisition of natural raw materials and energy, the growing social importance of environmental protection and the development of a new technological processes have caused that the original tendency of manufacturers has changed, to dispose of wastes as worthless substances. From the point of view of environmental protection, it can be stated that combustion is one of the safe ways of disposal of municipal and hazardous waste and for many types of waste it is the only way of its safe disposal. Several types of secondary solid waste arise in thermal waste disposal, which must be safely deposited or reprocessed. Given the situation, that the composition of secondary solid residues is very diverse, an assessment of their hazardous properties is needed. The ash / slag contains relatively high values of heavy metal oxides, which may pose a significant risk of leaching when improperly deposited in landfills. Another solid fraction after waste incineration is fly ash, which is more dangerous than slag / ash. Emphasis is placed on the process of their preliminary adjustment in the preparation. Appropriate procedures can minimize cases misuse. Samples of solid residues after incineration of waste from hazardous and municipal waste incinerators in the Czech Republic were selected for the experimental part of the work. The interest in exploring the binding properties of these substances is based on the requirement to immobilize their toxic components. The possibility of safe residence of solid residues obtained by waste incineration, ie. the needs of their material use, it was a necessary to test or compact them. The result is a compact material whose water leachate allows safe storage of these often hazardous wastes. It has been found that the addition of cement in an amount of 30 to 60 wt. % is able to ensure consistency of originally loose materials. However, it is necessary to approach the issue individually.
