Abstract
Foundry is the main manufacturing methods for producing castings which are the basic material for any type of production. The casting obtained from the foundries are fed through various machining and manufacturing process for producing different type of components needed for many type Automobile, Industrial, Consumable and commercial products. It is an ancient manufacturing process invented by
our ancestors and is in nature human by birth itself from Harrappa and mohanzathara Civilization days, say before 3000years. During foundry process A by product called waste sand is obtained. It comes as waste after moulded component is removed from the sand moulds.
The consumed sand converted to hard residue thrown to dust yard or dumped as debris near the road sides ponds or river sides. Now a day, disposal of these kind of foundry wastes are cumbersome and tedious job for the foundries. Presently in small and medium scale foundry, resource consumption and environmental pollution are major problem caused by the waste sand.. Foundries cannot dump the used sand in a quarry. But, it is essential to focus on reclamation for green initiatives in foundry industry because of sand availability are also a problem. There are some large –scale foundries that are importing sand. Pollution control norms are stringent.
Key words: Foundry resources, Used Foundry Sand, Sand
Reclamation, Environmental Protection. Green Technology, Pollution Control
