Akzo Nobel profile
• A Dutch multi-national company created in 1969.
Roots trace back to 1777
• Serving customers with healthcare products,
coatings and chemicals
• 17 billion $ in net sales (2003)
• More than 60 000 employees
• Operates in about 80 countries

LCA from salt extraction to Stora Enso cardboard
Electrolysis

Environmental hotspots in
the production of NaOH?

Salt extraction
Environmental profile of salt
improved from 1998 to 2000?
Stora Enso
cardboard
Have paper chemicals
a significant influence
on the environmental
profile of cardboard?
Sustainable
Development
Business value of the LCA example
• Salt extraction:
− CO2 decrease => good economy e.g. energy savings, CO2
emission trading
• Electrolysis:
− Relevant information to meet NGO´s specific concerns e.g. SO2
and NOX
− Focus on the transport instead of emissions from the site => avoid
sub optimization
• Pulp & Paper:
− Sales support
− New business or more important; we don’t loose existing business!

Environmental Risk Assessment (ERA) for an
asphalt additive (Wetfix)
The asphalt additive (Wetfix):
•Promotes the adhesion between bitumen
and aggregate (hot mix) in order to
extend the life time of an asphalt pavement
•Is used in low concentrations (0,2-0,4% weight of
bitumen)

Comparison between LCA &
Environmental Risk Assessment (ERA)
ERA : Not including resource consumption etc.
LCA : Difficult to include inherent properties

Business value of the ERA and the ERA/LCA example
•
ERA:
− Avoid unwanted surprises
− Are more toxicity tests and/or exposure measurements useful
and necessary => reduced costs
− Comply with REACH ! (the new EU chemicals legislation)
•
ERA/LCA combination:
− More complete picture of complex issues => increased
credibility
− Provides a wider perspective on possible consequences of
banning a substance from a market
− Is used for marketing today

Other conclusions
from an eco-efficiency study
• Environmental costs were found to be a relatively
large part of the total costs of the studied products
• For the surfactants (used in the colorants)
4,5% – 6,5% of the sales price
• The environmental costs are higher than normally
(~1%) reported to authorities and statistics
