Life cycle assessment of high value activated carbon production based on mass and functional performance metrics.

ABSTRACT: The production of activated carbon (AC) from biomass holds substantial environmental potential, but its impact varies widely depending on the synthesis methods employed. However, unreliable experimental data results in inconsistent life cycle assessments (LCA), often dependent on generic or highly localized information. Most available data focuses solely on production metrics, neglecting crucial performance-based indicators. This study conducts LCA for a conceptual AC production facility designed to produce 1 kg of AC per batch of coconut shell (CS), particularly examining potassium hydroxide (KOH) and sodium hydroxide (NaOH) activation routes. Environmental impacts (EIs) are evaluated using two functional units-mass-based and adsorption-based-and span eighteen metrics, including six key o
