Energy and Environmental Profile of the Aluminum Industry
This detailed report benchmarks the energy and environmental characteristics of the key technologies used in the major processes of the aluminum industry. ( PDF 2.5 MB)
Aluminum Processing Energy Benchmark Report
Substantial energy efficiency gains have been made in the aluminum industry over the past forty years, resulting in a 58 percent decrease in energy utilization.
However, as shown in the recently completed U.S. Energy Requirements for Aluminum Production, Historical Perspective, Theoretical Limits, and New Opportunities, room for improvement remains. Overall, the industry is operating at more than three times its theoretical minimum energy requirement. This report provides detailed appendices, statistical data, and descriptions of the fundamental chemistry, as well as practical aspects of aluminum production processes. It compares current usage levels and theoretical minimum energy requirements to demonstrate that large energy saving opportunities exist. ( PDF 3.6 MB)
Inert Anode Report
This ASME report provides a broad assessment of open literature and patents that exist in the area of inert anodes and their related cathode systems and cell designs, technologies that are relevant for the advanced smelting of aluminum. The report also discusses the opportunities, barriers, and issues associated with these technologies from a technical, environmental, and economic viewpoint. ( PDF 9.0 MB)
