Industrial Ecology and Metal Production
As the world's population and global standard of living increase, the role of metals in the economy will not diminish in the 21st century, despite substitution and dematerialisation trends. Industrial Ecology is an emerging science that attempts to bring together physical, biological and social scientists and develop the tools for good management of the planet in the long run. In engineering terms, Industrial Ecology is defined as the reconfiguring of industrial activities with full knowledge of their environmental consequences. Production and use of materials must take into account the needs of both market and environment. Dispersive uses of metals will be phased out, as is being done with lead in gasoline, and post-use recovery of materials and energy will increase. This will result in an advantage for metallurgical processes that can use as feed materials concentrates as well as metal scrap and waste streams, such as bath smelting processes and slag resistance electric furnaces. The paper also discusses how metal extraction technologies, developed in the 20th century to provide essential materials to humanity, can be applied for the benefit of both mankind and environment in the 21st century.
