HALE
Project: Reducing energy consumption in electrolysis
Aluminum is produced through an electrolytic process where
an increase in electrical current can increase metal production.
In recent years, Alcan's Lynemouth U.K. Smelter has introduced
the High Amperage Low Energy (HALE) project to capitalize
on this potential.
Energy
efficiency at Quebec alumina plant
At the Vaudreuil alumina complex in Quebec, Canada, an
internal Continuous Improvement project set out to minimize
steam consumption within the process as well as in the utilities.
Reduction
of GHG emissions through biomass
Alcan's Lynemouth Power Station is the most efficient
coal-fired power station of its kind in the U.K. Following
permission from the U.K. Environment Agency in December 2003
for industry to burn biomass as a commercial fuel, Lynemouth
began investigating the viability of this alternative.
Reduction
of fossil fuel use in Iceland
In early 2004, the management team at Alcan's ISAL smelter
in Hafnarfjordur, Iceland, focused on further reducing energy
consumption related to the heating of casting centre furnaces.
Conversion
to natural gas – Alcan Gove Australia
Delivery of natural gas to Gove will ensure a secure,
economical and long-term energy source for the refinery, have
a positive environmental impact, as well as provide opportunities
for new and existing businesses in the Northern Territory
and Queensland states.
"Save
Watts" program at Ronchin (ECL) in France
The Ronchin facility (technology and equipment sales)
in France launched a program in February 2004 to reduce electricity
consumption through the participation of all employees.
