Sustainability assessment of lignocellulosic biorefineries under uncertainty

Biorefinery concepts refer to the integrated production of food, fuel, power, commodity chemicals, and polymers from biomass, mimicking the structure of a fossil-based refinery. The use of lignocellulosic biomass as feedstock for biorefineries has been pro ...

Life cycle assessment of biofuels: Energy and greenhouse gas balances

Edgard Gnansounou, Arnaud Dauriat, Luis Alberto Panichelli, Juan David Villegas Gomez

The promotion of biofuels as energy for transportation in the industrialized countries is mainly driven by the perspective of oil depletion, the concerns about energy security and global warming. However due to sustainability constraints, biofuels will rep ...

Techno-economic and environmental evaluation of lignocellulosic biochemical refineries: need for a modular platform for integrated assessment (MPIA)

Edgard Gnansounou, Juan David Villegas Gomez

Ethanol production from lignocellulosic residues has potential to significantly improve sustainability of biofuels for transport by avoiding land-use competition with food crops and reducing impacts related to agricultural inputs. However, high production ...

Energy and greenhouse gas balances of biofuels: biases induced by LCA modelling choices

Edgard Gnansounou, Arnaud Dauriat, Luis Alberto Panichelli, Juan David Villegas Gomez

Estimating greenhouse gas (GHG) balances of biofuels is subject to significant biases stemming from modelling choices about system definition and boundaries, functional unit, reference systems and allocation methods. This paper investigates extent to which ...
