Performance, life cycle assessment, and economic comparison between date palm waste biochar and activated carbon derived from woody biomass

ABSTRACT: Currently, comparisons between biochar and activated carbon in terms of performance, environmental impacts as well as financial implications are limited. In this study, biochar sourced from date palm waste were analysed using gate-to-grave life cycle assessment approach and results were compared to activated carbon derived from woody biomass. Simapro 8.5 software was used to quantitatively simulate the environmental impacts of both adsorbents. Date palm waste biochar and activated carbon global warming potentials (GWPs) were found to be 1.53 and 8.96 kg CO2eq/kg respectively. The cumulative energy demand (CED) for producing date palm waste biochar was found to be 20.3 MJ/kg, whereas, activated carbon resulted in 119.5 MJ/kg. Both adsorbents’ performance in terms of adsorption capacity were
