SIEVE SRL

SIEve is an innovative startup that has developed a low-cost, on-site regenerable filter for the physical-chemical treatment of wastewater. Its advanced technology efficiently removes multiple classes of pollutants—including organic compounds, heavy metals, and pathogens—in a single step, offering a sustainable and cost-effective solution. Designed with full circularity in mind, SIEve repurposes Red Mud—a hazardous, abundant, and unused metallurgical slag—as its core raw material, transforming industrial waste into environmental value. Currently backed by Tech4Planet and NextStep Accelerator, driving innovation toward a cleaner, more sustainable future.
