This paper discusses the fate of nitrogen, phosphorus and carbon in wastewater and sludge management and argues that the fate of these elements may have a large impact on the life cycle environmental performance of such systems. The effect of changing plant operation to increase N removal and to add also P control, thereby shifting the transfer of the elements between different media, was studied, using data from mass and energy balances and from literature. A sensitivity analysis was also made. It was shown that LCA results are considerably affected by both considered operational changes and by assumptions on the magnitudes of some parameters.
