Sustainable Industrial Ecology

This study establishes an integrated life cycle analysis and techno-economic assessment to evaluate costs and carbon footprint impacts of an integrated forest biorefinery that produces lumber, industrial sugar and wood pellets in a planned biomass conversion center in the Pontiac region of Quebec (Canada). An integrated evaluation approach combining levelized cost and carbon footprint accounting was adopted for assessing the implementation of this novel advanced biorefinery concept taking into account different biomass feedstock, diversified product portfolio (sugar, lignin, bio-oil, electricity and lumber) and multiple biomass conversion technologies. The conclusion of this study is that if the GHG emission is considered as the basis of the ranking system, the production of wood pellets would emit less (1.2 kg/T) and that of lumber, and sugar would emit most respectively (3.3 kg/T and 98.4 kg/DT). This is whereas if the ranking would be performed based on the cost, the sequence would be the production of lumber, pellet, and sugar.
