Lot of foundry sand is wasted and dumped during the casting process thereby increasing the load on environment and making the economics of the small foundries unattractive. It is hence desired to develop and commercialize a reclamation process that recovers the sand and makes it reusable. A pilot plant is built by IIT in the field which is serving few foundries in the nearby area. A startup is formed to commercialize the research findings. The work involves understanding the scientific aspects of chemical reclamation process patented by IITB.
