Dust and sludge are collected in the abatement equipment (filters) attached to the iron and steelmaking processes. Sludge is produced from dust or fines in various steelmaking and rolling processes and has a high moisture content. The dust and sludge removed from the gases consist primarily of iron and can mostly be used again in steelmaking.

The remaining 30 percent of spent sand from the metal casting industry originates in the cleaning room. Currently, reclamation of this sand is not attempted. Sand is removed from metal castings primarily by shot blasting. During this process, metal flashing is removed along with sand, and some metal is smeared onto sand surfaces.
