Abstract:

Based on the potentials of wood and straw in Austria the most interesting bioethanol concepts, which guarantee the efficient use of wood and straw, were identified and then modeled with IPSEpro: Bioethanol from cellulose and hemi­cellulose as a substitute for gasoline and co­products (e.g. electricity, pellets) from lignin and process residues are produced. The whole process chain was analyzed on technical aspects, and on economic and environmental aspects by e.g. life cycle analyses (LCA). Most interesting results are: all concepts are energy self­sufficient (process heat from residues), type and amount of co­products influences technical, economic and environmental performance; priority to integration of ligno­cellulosic bioethanol plant in existing infrastructure, e.g. from wood in P&P­industry; GHG­reduction between 41% and 76% possible; costs of ligno­cellulosic bioethanol between 0.6 ­ 1 €/l gasoline equivalent.
