RCRA Online Number:11900
Organization of Recipient:American Foundrymen's Society
Description: Foundry sands normally become wastes when a sand mold is broken at a "shakeout table" and the sand is separated from metal castings. If the sand is destined for reclamation rather than direct reuse, the sand is a spent material and solid waste (SUPERSEDED: SEE RPC# 3/28/2001-01). Nonthermal reclamation of foundry sands (screening sand to remove metal residuals) is an exempt recycling process. Thermal reclamation using a controlled flame to destroy organics in the sand is incineration subject to Subpart O. Spent foundry sand destined for direct reuse as a fluxing agent in primary copper smelting is not a solid waste. Treating hazardous spent foundry sands with iron to stabilize metal contaminants could constitute impermissible dilution (SEE ALSO: 60 FR 11702, 11731; 3/2/95). Most spent foundry sand that is hazardous exhibits the toxicity characteristic for lead (D008) or cadmium (D006). An estimate that 4% of foundry sand sent for disposal is hazardous is provided. Sand used in a leaded brass manufacture is more often hazardous than other foundry sands.
