Sand or ceramic media is the largest foundry process waste, typically constituting about 70% of total waste volume. Environmentally it is becoming increasingly more difficult to dispose of these great quantities of waste sand or ceramic into a landfill. But waste is not the only challenge related to spent foundry sand.

For the average small plant reclaiming 2 to 3 tons of sand per hour the cost should not exceed $15 per ton. With new foundry sand costing $40-$45 a ton, the saving for the average foundry over a period of time is well worth the investment for the reclamation system as outlined. Several plants are now in operation using this system very successfully.
