Abstract:
The role of cogeneration and CO2-compression stages is studied in the sustainability of biochemical-platform biorefineries for producing lignocellulosic bioethanol. Olive tree pruning is employed as feedstock for a 1000 ton/day capacity biorefinery. Selling compressed CO2 from fermentation as a byproduct provides a slight economic advantage (i.e. 2% lower TPC) with respect to a standard biorefinery design including a co-generation stage. Nevertheless, the standard design with co-generation is more environmentally sustainable than either the standard plant with CO2 compression or a standard plant with neither cogeneration nor CO2 compression stages. Overall, the standard plant shows to be more sustainable. However, the results of the sustainability analysis are highly dependent of indicator weighting coefficients.
