The webinar will address the scientific and technical issues related to the management of waste incineration residues. Details will be given on the different types of incineration residues, typical composition and technical properties, environmental behavior, as well as technical options for treatment, reuse and final disposal.







TOPICS THAT WILL BE COVERED:

1. Types of incineration residues
2. Composition and characteristics of incineration residues

2.1. Physical properties
2.2. Chemical Characteristics
2.3. Mineralogical composition
2.4. Leaching behavior and potential environmental impact

3. Treatment of incineration residues

3.1. Extraction and separation
3.2. Chemical treatment
3.3. Thermal treatment

4. Utilization options
5. Final disposal strategies
