Assessment of a Novel Alder Biorefinery Concept to Meet Demands of Economic Feasibility, Energy Production and Long Term Environmental Sustainability

T. Thomsen, J. Ahrenfeldt & S.T. Thomsen
A biorefinery concept based on alder tree plantations on degenerated or marginalized soils is developed to illustrate how it is possible to comply with indicators of economic feasibility, fossil fuel depletion concerns and long term sustainability issues. The biorefinery is based on grey alder (Alnus incana), and provide the following end products: Heat and power, bio¬pharmaceuticals (diaryl heptanoids), Bio-SNG, ethyl acetate, replenished soils and a carbon sink. Several system setups were examined and compared. The...
