The present work aims to investigate the potential of Aspergillus sp. in the bioleaching of waste foundry sand and to support the growth of Coriandrum sativum. The WFSs were from aluminum, iron and steel foundries. This study also assesses the availability of Al, Cd, Co, Cu, Fe, Mg, Ni, Pb, and Zn in WFS. Although there were differences in the amounts of metals accumulated by the various plant species, excessive amounts of heavy metals were not taken up, regardless of WFS treatment. Hence, our study is designed to bioleached the metals present in waste foundry sand using Aspergillus sp. and to use it as a biofertilizer for the growth of Coriandrum sativum. The waste foundry sand was collected from different regions around Chennai and Coimbatore districts. The physical properties such as coloration like (black, and light black). Texture (Round and spherical), Moisture (0.75, 0.97), temperature (Room Temperature), solubility (dissolved and settled) and pH were measured (5-9) using standard protocols. The chemical properties of treated and untreated waste foundry sand were observed. The analyzed shows increase the level of aluminum and iron and decreased levels of Copper and Zinc in waste foundry sand. The waste foundry sand was bioleached using Aspergillus sp. The treated and untreated sand was later used for growing Coriander sapling under controlled conditions and observed for the metal absorption after growth. Our observations provide a supportive document on bioleaching of WFS by Aspergillus sp. was adequate in the growth of herbal plant Coriandrum sativum.
