An integrated life cycle and water footprint assessment of nonfood crops based bioenergy production

Abstract Biomass gasification, especially distribution to power generation, is considered as a promising way to tackle global energy and environmental challenges. However, previous researches on integrated analysis of the greenhouse gases (GHG) abatement potentials associated with biomass electrific...
