                                                The main objective of this topic is to reclaim the spent foundry sand to promote green manufacturing practices around the world. The process of reclamation can bring considerably more cost reduction and a contamination free environment around the foundry area.  The current method of reclamation has a reclamation efficiency of 35-40% which is comparatively less than the sand intake. This proposed process of reclamation will bring an efficiency of 85-90% which will promote green manufacturing practices in the field of manufacturing.

Requirements of reclaimed sand

 The technical requirements of reclaimed sand are

         Superior hot strength
         Low binder additions
         Low sand to metal ratio
     •         Good permeability
