technological scheme of the foundry is shown in Fig. 1. As can be seen from the scheme, in the foundry, such wastes as burnt molding earth, iron-containing dust, and metallurgical slags are generated. The most large-scale waste is spent foundry sand (SFS). SFS or burnt molding earth is formed when metal castings are knocked out of molds. In
