Integrated biorefineries - overall concepts
Process Design and Environmental Assessment of an Integrated Biorefinery for Bioethanol and Bio-Oil Production
Short Introductive summary
This work deals with the design , up-scale, and modelling of an integrated biorefinery for the conversion of Norwegian forestry residue into bio-ethanol (through enzymatic saccharification and fermentation of hydrolysate) and bio-oil (through pyrolysis of lignin-rich saccharification residue). The overall yield, including biochar from pyrolysis, is close to 65%. An environmental assessment is proposed to estimate the greenhouse gas emissions associated with the proposed biorefinery. Results show that the hydrogen source for the raw pyrolysis oil hydrotreatment (i.e., grey, blue, or green hydrogen) has a significant impact on the overall equivalent CO2 emissions. This work points out the importance of finding a trade-off between economic profitability (cost of hydrogen) and environmental sustainability.
