SUMMARY:

In accordance with recent changes in Brazilian legislation, all production processes are now required to account for the byproducts resulting from their operations and consider potential alternatives for appropriate disposal before resorting to sanitary landfills. Under this principle, the current study has delved into examining the properties of incineration bottom ashes from Healthcare Waste in a facility located in Paraíba. The aim is to assess the viability of utilizing these ashes in the impermeable barrier layers of the final cover of sanitary landfills.

To achieve this objective,  geotechnical and chemical-mineralogical composition tests were conducted to determine whether the material meets the necessary criteria for the proposed application. Mixtures were prepared using the soil typically used for the final cover of sanitary landfills, incorporating varying mass proportions of HMW ashes. Notably, all these mixtures displayed a saturated permeability coefficient in the order of 10^-7 m/s, approximating the hydraulic conductivity values to those recommended in the existing literature.
