Sewage Sludge Valorization for Collapsible Soil Improvement

The environmental problems caused by sewage sludge generated the growth of global population and urbanization are drawing attention scientific community worldwide to need developing sustainable solutions use that material. This work investigated possibilities using sludge, in wastewater treatment plants, as a strategy improve stabilize collapsible soils. Different soil–sludge mixtures, with 5%, 10%, 15% were analyzed. For characterization analysis interaction, physical, chemical, edometric experiments performed. results showed addition soil causes void index reduction, improves particle packaging, reduces collapsibility same specific dry apparent weights, i.e., be promising method for improvement
