Improved
vegetation around Quebec smelters
In 2004, international experts surveyed the condition
of the vegetation around Alcan's smelters in the province
of Quebec as part of a regular multi-annual environmental
follow-up.
New
equipment at Aluchemie yields PAH reductions
Alcan's Aluchemie facility in the Netherlands has been
producing prebake anodes since 1964. In the production of
anodes, key environmental releases are polycyclic aromatic
hydrocarbons (PAHs) and fluorides. In close collaboration
with local environmental authorities, an innovative fume treatment
was part of the installation of a seventh anode furnace in
November 2003.
Minimizing
environmental footprint in California
Global Pharmaceutical's Commerce plant (Medical Flexibles)
