SUMMARY:

According to recent changes in Brazilian legislation, every production process must know the by-products
arising from its operation, aiming at possible alternatives for appropriate destinations, before sending them to landfills Sanitary. Under this premise, the present study investigated the properties of bottom ash from incineration of Health Service Waste (RSS) from a power plant in Paraíba to analyze the possibility of using these in layers of waterproofing barriers for the final cover of sanitary landfills. To this end, several geotechnical and chemical and mineralogical composition tests to assess whether the material has the characteristics necessary for the intended use. Mixtures of soil used in the final cover of landfill were carried out with different proportions of mass RSS ash: 5%, 7.5%, 10%, 15% and 20%. All mixtures showed saturated permeability coefficient in the order of 10-7m/s, close to the conductivity coefficient values hydraulics recommended in the literature.
