This study explored the sustainable production of microalgal biochar for graphite applications through a life cycle assessment (LCA) of 12 scenarios varying in CO2 source, pre-treatment methods, and pyrolysis temperature. Biomass subjected to two-step torrefaction and pyrolysis at 700°C has the high...
