Representative adsorption-based CO₂ mitigation pathways for circular agricultural systems. (a) Agricultural-scale carbon sources and utilization routes, including greenhouse ventilation-based CO₂ capture and reuse, treatment of the gas from livestock manure fermentation, upgrading biogas through CO₂/CH₄ separation, rural direct air capture (DAC), algal cultivation, and biochar-assisted soil carbon sequestration. (b) Representative amine-functionalized and porous adsorbent systems, including biomass-derived activated carbons, porous silicas, zeolites, and metal–organic frameworks (MOFs), together with a schematic low-partial-pressure CO₂ adsorption behavior. This conceptual framework was developed from References^[2,4,5,10].
