4.1 Introduction. Used foundry sand (UFS) (Fig. 4.1) is a discarded material coming from ferrous (iron and steel) and nonferrous (copper, aluminium, and brass) metal-casting industry to create molds and cores. About 1 ton of foundry sand for each ton of iron or steel casting produced is used ( Siddique and Noumowec, 2008 ).

Shooting. In the shooting process a blow head filled with sand is pressurized with air, leading to the fluidization of the sand which results in a "fluid" consisting of an air/sand/binder mixture. This fluid flows from the blow head through shooting nozzles into the core box, repelling the air out of the box through venting nozzles.
