Regulatory Issues Associated With Salt Cake and Dross Processing in USA and Europe

This presentation addresses the changing regulatory climate towards aluminum dross and salt cake in Europe and in the United States. Although sporadic, the trend in the U.S. continues to be away from command-and-control regulation of these materials. This trend began in the early 1980s when the Environmental Protection Agency was successfully sued in court and prevented from classifying dross as a hazardous material. The situation in Europe is different. Because of Council Directive 96/61/EC from the European Commission, European Union member countries have all passed legislation that will essentially cause all salt cake and drosses to be reprocessed. The implementation date of the legislation varies from country to country: from 2001 in the United Kingdom to 2007 in Germany, France, Austria, Italy, and Spain. The European aluminum industry is urging the EC to use the approach adopted by the U.S. EPA, which declassifies the majority of aluminum drosses and salt cakes.
