What are the Environmental Considerations for Disposing of Spent Ingot Molds?
Disposing of a spent ingot mold should be handled as part of an aluminum plant’s responsible materials management process. An ingot mold is normally made from cast steel or specified high-temperature materials and is used to cast finished aluminum ingots for downstream remelting users such as die-casting plants and automotive suppliers. When it’s time to throw it away, the most important things to do for the environment are to identify the mould material, look for surface residues, separate recyclable metal, follow local trash rules, and choose replacement moulds that last longer so that they don’t have to be thrown away as often. Identify Material Composition and Surface Residues Before Disposal The first environmental step is to confirm what the ingot mold is made of and what remains on its surface after service. A typical ingot mold for aluminum may be traditional cast steel, a customer-specified material, or a proprietary material such as DuraCast® used for demanding h
