Abstract

This study proposes a sustainable waste-to-energy/biochar platform using a toxic microalgal biomass waste. In particular, CO₂-feeding pyrolysis of Microcystis aeruginosa (M. aeruginosa) waste was investigated, focusing on the analysis of gaseous pyrolysates and properties of biochar with a construction of mass balance. Also, the catalytic capability of biochar produced from M. aeruginosa was explored to reinforce the mechanistic impact of CO₂ on the pyrolysis process within the overall process level. Ni impregnated biochar composite was further synthesized and used as a catalyst to promote syngas formation in the CO₂-feeding pyrolysis process of M. aeruginosa.
