Life Cycle Assessment

(LCA)


Salt extraction

Electrolysis

Pulp & Paper

NaCl NaOH

Stora Enso cardboard

LCA from salt extraction to Stora Enso cardboard

Environmental profile of salt Environmental profile of salt improved from 1998 to 2000?improved from 1998 to 2000?

Environmental hotspots in Environmental hotspots in the production of NaOH?the production of NaOH?

Have paper chemicals Have paper chemicals a significant influence a significant influence on the environmental on the environmental profile of cardboard?profile of cardboard?


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


Comparison between LCA & Environmental Risk Assessment (ERA)

ERA : Not including resource consumption etc.LCA : Difficult to include inherent properties

Thorough Environmental Assessment


The potential role of Life Cycle Assessment in regulation of chemicals in the European Union according to the European Chemicals Bureau

SEA

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.

Strategies

• provide examples on how you can address different environmental sustainability issues within different parts of a company:

• Research & development• Marketing• Supply chain• Production• Environmental support
