摘要: Life cycle assessment (LCA) methodology is used to evaluate the environmental profile of a product or process from its origin final destination. In this paper we LCA current situation wastewater treatment plant and identify improvement alternatives. Currently, highest impacts are caused by stages with energy consumption, use biogas anaerobic digestion (95% burned in torch) destination sludge (98.6% for agricultural 1.4% compost). We propose four alternatives applications five compare them situation. The were incorporated decision support system prioritize most positive option. Using produce electricity combination heat provided best options since produced would be enough supply all t...
