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) Data evaluation
Exposure assessment
Risk Characterisation Ratio
RCR = PEC / PNEC
Effectassessment
PEC = Predicted Environmental Concentration
RCR < 1No risk!
PNEC = Predicted No-Effect Concentration
ERA life cycle

Environmental Risk Assessment (ERA) for an 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)
The asphalt additive (Wetfix):

LCA
Sustainable Development
Comparison between LCA & Environmental Risk Assessment (ERA)
ERA : Not including resource consumption etc.LCA : Difficult to include inherent properties
Thorough Environmental Assessment
Sustainable Development
The potential role of Life Cycle Assessment in regulation of chemicals in the European Union according to the European Chemicals Bureau
Basis for decision Decision

LCA
• ERA = Environmental Risk Assessment• SEA = Socio-economic analysis• LCA = Life Cycle Assessment

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

DANTESDANTES DANTES goals
• Demonstrate and evaluate environmental assessment and communication tools:
– Life Cycle Assessment (LCA)– Life Cycle Costing (LCC)– Environmental Risk Assessment (ERA)– Environmental Product Declarations (EPD)– Environmental Performance Indicators (EPI)
• Display strategies of how to use these tools in different functions within a company.
