Lael Eco-Efficiency Analysis Astaxanthin Feruary 12 th, 2004 Validated Eco-Efficiency Analysis Methodology Eco-Efficiency 1
The Lael An eco-efficiency analysis was performed in order to compare the environmental impacts and the costs from all life-cycle stages of the production and use of astaxanthin for salmon production. In the field of agriculture, astaxanthin, a carotenoid, gives salmon the characteristic pink colour hue. Whereas fish in the wild otain carotenoids transferred y organisms up the food chain, salmon in culture situations depend on the appropriate addition of pigments to the feed. The eco-efficiency analysis showed that the production of astaxanthin y chemical synthesis is clearly more eco-efficient than the fermentation of micro-organisms or the cultivation of algae.

Interpretation of the Eco-Efficiency Portfolio Astaxanthin via chemical process is the most eco-efficient alternative for the production of salmon (the distance from the diagonal is a measure for the eco-efficiency). The high environmental performance of the chemical production of astaxanthin is due mainly to the high energy consumption of the other alternatives. From a customer s point of view, all alternatives are economically equal. The costs for the customer are aout the same (market prices were used for the calculation). There are no additional costs to e calculated from a customer s point of view. Eco-Efficiency 12

Critical Review BASF s eco-efficiency was carefully examined and evaluated y independent experts of the Öko-Institut e. V. in Freiurg, Germany. Öko-Institut (Institute for Applied Ecology), a registered well-known non-profit association, was founded in 1977. The ojectives of the institute are to analyse and evaluate current and future environmental prolems, to point out risks, and to develop and implement prolem-solving strategies and measures. Extract from the summary of the report:...this expert s opinion concerns an eco-efficiency analysis carried out y BASF AG, in which three variants of astaxanthin production (chemical synthesis, iotechnology using yeasts/ fermenters, and production from algae/ ponds) are compared. The purpose of this expert s opinion commissioned y BASF is to ensure that the methodology of the ecoefficiency analysis is consistent and that the data used are suitale and expedient as regards the ojective. Öko-Institut e. V. comes to the conclusion that the eco-efficiency analysis presented was conducted with a consistent methodology and that the data are applied expedient with regard to the ojective and the framework examined in the study. The presentation of the results is largely clear and plausile... Authors: Dipl.-Ing. Carl-Otto Gensch (Project Leader), Dipl.-Ing. (FH) Kathrin Graulich, Dr. Jennifer Teufel (all Öko-Institut e.
