Life cycle assessments and eutrophication. A concept for calculation of the potential effects of nitrogen and phosphorous

Technical Report:

Abstract

The aim with this report was to make an attempt to calculate the potential effect, on aquatic ecosystems, by nitrogen, phosphorus and organic material to be used in life cycle assessment. In addition, to identify lack of knowledge that has to be study for improving the LCA analysis. It is suggested in this report that the amount of nitrogen and phosphorus transported to the aquatic environment are recalculated to the amount organic carbon that nitrogen and phosphorus can mediate. The produced organic carbon is then used to calculate the potential oxygen consumption by the material. This is made by using the reversed photosynthesis including oxygen consumption by nitrification. By the use of the relationship it is revealed that 1 mol organic carbon consumes 1.3 mol oxygen. The value of COD by the organic material emitted to the aquatic ecosystem can then be added to the calculated oxygen consumption. Examples are given in the report on non-site specific and site specific calculations. 17 refs, 4 figs, 1 tab
