This study examines corn stalk biochar (CSB)-enhanced mortar as an innovative material for carbon capture and CO2 sequestration. CSB, a renewable agricultural byproduct, was incorporated into cement at varying concentrations (2.5% to 75%), its effects on the mortar’s physicochemical properties, ability support algal growth, absorption capacity of algae were analyzed. Characterization CSB showed high content (62.3%), significant porosity, large surface area (680.3 m2 g−1), making it ideal gas capture. At low (2.5%), slightly improved compressive strength density. However, higher levels (5% 75%) led reductions (p < 0.05) in density, while water increased. sequestration monitored from growth studies revealed that both Chlorella sp. (TISTR 8262) Scenedesmus 9384) thrived CSB-enhanced mortars. 75% concentration, achieved 24.2-fold increase biomass by day 12, outperforming sp., which 26.6-fold increase. also with biochar. Mortars 86% ratio without algae, adding boosted this nearly 100%, highlighting synergistic effect photosynthesis. Higher accelerated stabilization, reaching saturation 8 CSB. efficiency than peak earlier maintaining greater efficiency. absorption, indicating biochar–mortar mixtures, particularly when combined provide promising solution enhancing green infrastructure.
