摘要: For the evaluation of environmental impacts direct life cycle emissions resulting from electricity generation biomass, various biomass conversion technologies (anaerobic digestion [five different plant types], combustion and gasification) are investigated on basis data existing plants in Austria. The analyzed accordance with ISO 14040 for assessment (LCA). impact CML 2001 base line approach covering 11 categories is used. results show how stages dominate emission profile that dominant differ depending technology. difference between up to a factor 12. In climate change, acidification eutrophication, anaerobic considerably higher than gasification due differences nature co-products (digestate or ash). LCA potentials improvement which could achieve reductions 10 50% certain categories. Based unweighed aggregation all results, comparison shows ranking led by using mainly energy crops, wood chips, primarily manure followed other types plants.
