AIMS
Alcan Integrated Management System.
Bauxite residue
A slightly alkaline residual slurry resulting from the extraction
of alumina in the Bayer process. The residue contains
mostly iron and silicon compounds left over from the bauxite.
CI
Continuous Improvement.
CLEAN
An internally audited initiative in our Packaging group to
ensure that high operating standards are maintained in
all facilities.
CO2 equivalent (CO2e)
The integration of all greenhouse gases based on their global
warming potential relative to carbon dioxide emissions.
ECL
Electrification Charpente Levage is an Alcan subsidiary with
worldwide sales and services in smelting engineering,
construction and equipment installation.
Effluent
Generally applies to liquid waste discharged as a result of
manufacturing operations, as well as public water treatment
facilities.
Greenhouse gas (GHG)
Carbon dioxide (CO2) and other emissions
that are believed to contribute to global warming, also known
as climate change.
GRI
The Global Reporting Initiative is a multi-stakeholder group
focused on developing and disseminating globally applicable
sustainability reporting guidelines.
ISO
International Organization for Standardization.
LCA
Life Cycle Assessments are part of the Product Stewardship
process to track the life cycle impact of our products.
LCLL
The Low Caustic Leaching and Liming process developed by Alcan
researchers as a means to treat spent potlining.
OECD
Organisation for Economic Co-operation and Development.
OHSAS
Occupational Health and Safety Assessment Series.
PAH
Polycyclic aromatic hydrocarbons (PAHs) are environmental
contaminants that are primarily derived from the incomplete
combustion of any organic material, including fossil or synthetic
fuels. In the aluminum industry, PAHs are generated in smelters
using older Söderberg technology. PAHs are also generated
by forest fires, wood heating and incineration.
Petajoules
A metric measurement unit for energy based on joules. One
petajoule = 1015 joules, or one million
gigajoules.
PFC
Perfluorocarbons (PFCs) include CF4
and C2F6
gases that have a very high CO2 equivalency
and constitute major contributors to greenhouse gas emissions.
PFCs occur as a result of anode effects in smelting operations.
Prebake
Prebaked technology applies to modern anodes used in the smelting
process that are "prebaked" as opposed to being
baked during the reduction process as with older Söderberg
technology. PAHs are captured in the anode-baking furnace
during the baking process.
Söderberg
Reduction cell technology used in the smelting process where
the anode is made of a block of paste that bakes as it approaches
the reaction zone in the cell.
Spent potlining
This is the residue lining, made up of bricks and carbon,
inside the pots used in aluminum smelting. When the lining
deteriorates to the point of being replaced, the material
becomes spent potlining (SPL).
TARGET
Alcan's greenhouse gas emissions reduction program.
UBCs
Used aluminum beverage cans.
United Nation's Global Compact
This is a voluntary international initiative launched by the
United Nations in 1999 that promotes the development
of a more sustainable and inclusive global economy.
VOC
Volatile Organic Compound.
WBCSD
World Business Council for Sustainable Development.
