Sumario:The study examines the reuse of hazardous waste incineration ashes in landfill leachate treatment. Its objective is to assess how the particle size distribution of the ashes affects the reduction of physicochemical parameters in leachate at the Caucaia Sanitary Landfill in Ceará, Brazil, thus valorizing them and minimizing their disposal in landfills. Two filtration columns with ashes of different particle sizes (F1 sieved and F2 raw) were set up. Leachate collected from the landfill was analyzed before and after filtration, demonstrating effectiveness in removing parameters such as phosphorus, nitrite, turbidity, nitrate, etc. The characterization of the ashes revealed differences between the samples, including varying levels of oxides and particle sizes. Results suggest potential use in pre-treatment to reduce pollutant loads before the primary treatment of leachate. The study underscores the potential of incineration ashes to enhance leachate treatment and reduce the environmental impact of improper disposal.
