Microbial degradation of waste foundry sand

Waste foundry sand (WFS) represent the highest amount of solid wastes generated by foundries.WFS is a by-product of ferrous and non-ferrous metal casting industries .Foundries successfully recycle and reuse the sand many times in a foundry. When the sand can no longer be reused in the foundry and it is termed as waste foundry sand. Indian foundry industry is the 4th largest casting producer in the world. The majority (95%) of the foundry units in India falls under the category of small scale industry. These foundries generates approximately 17, 10000 tones WFS/year. Microbial research and the need for new methods for the removal of heavy metals and other contaminants led to the great deal of expansion in the field of biological methods of industrial waste clean-up. This study aimed to present the utilization of microorganisms treated WFS in Horticulture. This experimental investigation was performed to evaluate the properties of treated and untreated WFS and the sand was partially replaced with WFS. Physical and chemical properties analyzed between treated and untreated WFS. In Horticulture instead or with sand the treated sand WFS can be used.
