A computer implemented system for optimization of sand for reducing casting rejections in a foundry utilizing the existing foundry components or machinery. The system is accessible online via a computer network. The system is enabled to provide a predicted or prescribed solution for the optimization of sand using at least a parameter relating to the aforementioned sand. Further, the system is enabled to determine the parameters contributing to casting rejections and provide a corresponding solution for reducing the rejections in the next casting batches for the particular foundry. The system includes a user interface module for enabling users to upload foundry related data into the system, a reporting module enabling the user to generate and understand current statistics of the foundry, and a processing engine which enables the system to perform mathematical computation of user queries and provide the desired predicted or prescribed solution to the user for the foundry.
