Registration, Evaluation and Authorisationof
CHemicals
EU New chemicals policy - REACH

• Merging of 2 current systems for new (1980-) and
  existing (-1980) chemicals into a new system
• Registration of all chemicals gt10 tonne/year in a
  central database
• Main responsibility for collecting and evaluating
  data lies on the producers and importers of
  chemicals
• Legislation 2 years from now (2007?)
• Progressively installed, completed 2018

Life Cycle Assessment (LCA) ERA
LCA Including all activities from cradle to
grave Potential environmental impacts from
activities, e.g.Resource useGlobal
warmingWastes
ERA including production, formulation, use and
waste of chemical Risk of impacts on ecosystems
(living organisms) from releases of a chemical
product,
Difficult to include direct effects of substances
on ecosystems and humans

Weighting factors
Relevance weighting

• Societal weighting
• - based on public and expert opinions on the
  relative importance of environmental, health
  and safety impact categories
• - differs between regions and countries

17
Societal weighting factors
18
Costs analysis

• Included costs depend on functional unit
  (benefit)
• Costs for the end customer sales price
  costs during use disposal costs
• Varies depending on e.g. the durability of
  the product

19
Eco-efficiency evaluation of colorants
Comparing the BASF eco-efficiency method with a
study made by Akzo Nobel
20
Environmental and economic impact

• LCA-based environmental impact
• Consumption of energy
• Consumption of resources
• Land use
• Emissions

• Economic impact
• Environmental costse.g. environmental taxes,
  tests, investments on site

• Weighting method
• According to EPS

21
Eco-efficiency results
22
Other findings

• Eco-efficiency analysis not time consuming if
  based on collected LCA data
• Environmental costs found to be a relatively
  large part of the total costs of the studied
  colorants
• Environmental costs of the surfactants (used in
  the colorants) 4,5 6,5 of the sales price
  (1 normally reported)
