It accumulates in soil and water, contaminates the food chain, and causes severe health problems, including kidney damage, anemia, and cancer. Industries involving the production of pigments, batteries, and alloys discharge wastewater containing high levels of cadmium. Hence, wastewater can serve as a valuable and viable source of cadmium, reducing the need for costly and environmentally damaging mining and refining activities. This study aims to recover cadmium from wastewater using bioprecipitation. Ureolytic bacteria from rhizospheric soil were used to separate cadmium from synthetic wastewater of different strengths. The recovery efficiency of the bioprecipitation method was more than 95%, according to the atomic absorption spectroscopy (AAS) analysis. X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS) studies were conducted to identify the residue. In conclusion, bioprecipitation method has been found to be an effective and sustainable approach to recover cadmium from wastewater, making it a promising solution to economic and environmental challenges. This method is efficient, cost-effective, and easy to operate, making it suitable for in-field applications. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.BioprecipitationOtaviteRhizosphereUrea hydrolysis
