Peter Entner (Alusuisse-Lonza Services Ltd) was session chair of Reduction Technology IV: Operational performance improvements This session was opened with a paper on the economics of shutting and restarting primary aluminium capacity. Driscoll reports that extensive efforts and preparation are required both to close capacity in an orderly manner and to restart idled capacity. He presented a comprehensive analysis of the costs of shutting capacity, maintaining idled capacity, and restarting potlines in a typical smelter. Technical aspects and commercial data and costs depend on a variety of shutdown and restart conditions. Additionally, he examined the time required to bring capacity back on-line for several scenarios, and discussed the economic impact of idled capacity.
