Efficiency Opportunities for Metal Casters
Foundries and die casting operations specialize in melting a wide variety of metals and alloys and casting them into desired shapes. Often, these facilities also engage in heat treating to change the metallurgical and mechanical properties of a cast part. Castings are used in 90% of all finished manufactured parts. For more information on Metal Casting, see the U.S. EPA’s 2008 Sector Strategies Performance Reports: metal casting [PDF 2MB] and iron and steel operations [PDF 1.9MB].
In Minnesota, the metal casting industry uses 2,700,000 MMBtus and generates volatile organic compounds (VOCs), other organics, air emissions, and solid and hazardous waste. Pollution prevention and energy efficiency opportunities exist within many metal casting facilities and can help you reduce your environmental impact and costs. Specific opportunities depend largely on your type of operation, metal and non-metal inputs, processes, and equipment.
