Gasification versus fast pyrolysis bio-oil production: A life cycle assessment

A life cycle assessment was performed to compare the sustainability of gasification and fast pyrolysis processes for producing bio-oil using agricultural wastes from biomass. The objective carry out environmental analysis associated with production 1 MJ different biomasses both thermochemical determine which process is more respectful environment. revealed that detrimental environment all under study. In addition, greenhouse gas emissions over a 100-year time horizon were calculated, thereby demonstrating CO2 yield higher than those CH4 N2O in processes. Furthermore, gain comprehensive overview, divided into equipment blocks evaluate their individual impacts. Almond shell, pistachio shell olive stone identified as minor amount feed needed produce bio-oil. This determined stage separation pyrolysis, main contributors mid-point impact categories. Finally, most environmentally friendly option
