Optimierung und Bewertung der Produktion von Getreidekorngut als Rohstoff für die Bioethanolerzeugung
(2001) Rosenberger, Alexander; Aufhammer, Walter
Varied cultivation of high yielding winter cereals to be used as bioethanol grains were examined regarding agronomic and fermentation traits as well as with respect to energetic, economic and environmental aspects. Empirical data were taken from biennial factorial field trials with winter cereals at two different experimental sites of Hohenheim University. These are the central conclusions: A-state-of-the-art conversion process presupposed, the cultivation of high-yielding cereals in crop rotations including previous legume crops is an energetically and economically efficient option to optimize the production of bioethanol grain and hence of bioethanol. From the ecologic view, crop production aligned to high grain yields is conflicting with respect to the enhancement of fossil primary energy conservation and thus the avoidance of greenhouse gas emissions relative to the reference fossil fuel and incremental releases of other ecologically relevant substances as compared to low-input crop management.
