1 Sustainable Development Akzo Nobel and Sustainability AIChE conference Atlanta, April 14, 2005 Klas Hallberg Sustainable Development group Akzo Nobel (Sweden)

2 Sustainable Development Agenda Akzo Nobel company profile Practical use of eco-efficiency tools today −Life Cycle Assessment from salt to cardboard −Environmental Risk Assessment of an asphalt additive −Eco-efficiency evaluation of colorants The DANTES project - an example of openness in communication between companies and the society

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

5 Sustainable Development Agenda

6 Sustainable Development Life Cycle Assessment (LCA)

7 Sustainable Development Salt extraction Electrolysis Pulp & Paper NaCl NaOH Stora Enso cardboard LCA from salt extraction to Stora Enso cardboard Environmental profile of salt improved from 1998 to 2000? Environmental hotspots in the production of NaOH? Have paper chemicals a significant influence on the environmental profile of cardboard?

8 Sustainable Development Business value of the LCA example Salt extraction: −CO 2 decrease => good economy e.g. energy savings, CO 2 emission trading Electrolysis: −Relevant information to meet NGO´s specific concerns e.g. SO 2 and NO X −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!

9 Sustainable Development Agenda

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

11 Sustainable Development 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):

12 Sustainable Development Simplified life cycle of the asphalt additive (Wetfix) Production of Raw Material 1 Transport of Raw Material 1 Production of Raw Material 2 Transport of Raw Material 2 Extraction of Resource B Refining of Resource B Extraction of Resource A (eg. natural gas) Production of an asphalt additive Use of product Waste handling of Product ERA LCA

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

14 Sustainable Development Comparison between LCA & Environmental Risk Assessment (ERA) LCA Starting point: one application UseRaw materials Production/formulation ERA Starting point: “the substance”

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

16 Sustainable Development Comparison between Lime, Cement & Wetfix (asphalt additive) from a life cycle perspective of a road CO 2 emissions [kg] / km highway Hot mix Lime Cement Wetfix

17 Sustainable Development 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

18 Sustainable Development Agenda

19 Sustainable Development Eco-efficiency evaluation of an old and a new colorant used in water based paint Applying the BASF eco-efficiency method on a study made by Akzo Nobel on a study made by Akzo Nobel

20 Sustainable Development LCA-based environmental impact Consumption of energy Consumption of resources Land use Emissions Toxic potential Risk potential Environmental and economic impact LCA-based environmental impact Consumption of energy Consumption of resources Land use Emissions Weighting method According to “EPS” Weighting method According to BASF Economic impact Environmental costs Economic impact Price

21 Sustainable Development Eco-efficiency results 0,0 1,0 2,0 0,81,01,2 Cost (normalized) Environmental impact (normalized) Old Colorant New Colorant

22 Sustainable Development 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

23 Sustainable Development Agenda

24 Demonstrate and Assess New Tools for Environmental Sustainability DANTES A demonstration project for sustainable development

25 Demonstrate and Assess New Tools for Environmental Sustainability DANTES Project information Supported by the EU LIFE - Environment Programme Period:2002 – 2005 (August 31) Partners:Akzo Nobel Surface Chemistry ABB Stora Enso Chalmers University of Technology

26 Demonstrate and Assess New Tools for Environmental Sustainability DANTES 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.

27 DANTES Demonstrate and Assess New Tools for Environmental Sustainability 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

28 Demonstrate and Assess New Tools for Environmental Sustainability DANTES is a smorgasbord! Environmental Product Declarations Transportation and environment Key Performance Indicators Sustainability issues in R&D Environmental Management Systems Energy efficiency CO 2 emission trading Exposure scenarios Sustainability information on the WEB Eco-efficiency evaluation Environmental Risk Assessment Environmental education Supplier evaluation Life Cycle Cost Environment CommunicationEngineering Economy LCA

29 – the DANTES project website Between 3000 and 4000 visits per month!
