  • The application of the Life Cycle Impact Assessment (LCIA) methodology to analyze the environmental burden of appling the digestates to corn field including different swine waste treatment systems was investigated. The first part of LCA is an inventory of parameters used to emissions released due to the system under investigation. In the following step, the Life Cycle Impact Assessment, the inventory data were analyzed and aggregated in order to finally get one index representing the each environmental burden. Each corn field applied with the aerobic and anaerobic digestates including different swine waste treatment systems was used as an example for the life cycle impact analysis. With analyzing the agricultural environmental burden, it observed that the effect of corn field applied aerobic digestate including digestion system was 7.6 times higher at eutrophication effects, but global warming potential effect was 0.9 times less than its applied anaerobic digestate.
