The volcanic soils of southern Chile have demonstrated a high capacity to adsorb environmental pollutants, but for an industrial application, a stable solid material is necessary. The objective of this work was to produce a stable ceramic material through a process involving volcanic soil–polyurethane foam produced with recycled polyethylene terephthalate (PET)–polyols, and further thermal treatment. The selected foam formulation with 35.4% volcanic soil (< 63 µm) seems to be the most suitable for thermal treatment, with temperature steps at 700, 850, 1000 and 1200°C. The porous ceramic material obtained has a stable solid form and an improved chlorophenols adsorption capacity (comparable to natural zeolites) that makes it suitable for advanced wastewater treatment and landfill leachate depuration.
