The increase of carbon dioxide emissions and the global warming consequences is today a considerable environmental concern. On the contrary, the rapid growth in the energy consumption throughout the world has exacerbated the CO2 emissions to the atmosphere. Accordingly, carbon capture sequestration and utilization have been considered as a potential emission mitigation strategy. In this way, several strategies and technologies including: absorption, membranes, adsorption etc. have been proposed, which adsorption technology using solid sorbents due to the lower environmental side-effects also lower energy consumption is one of the most favorable strategies. However, despite the significant efforts made for developing novel solid adsorbents for CO2 mitigation, still the elements of cost and synthesis have remained as main challenges. To this end, biochar carbon materials have been employed as a source of adsorbent through CO2 capture and sequestration process not only to satisfy these factors but also as a pathway to the solid waste management. Herein, the key concepts on the carbon capture and sequestration also adsorption processes have been discussed. Next, the capability of biomass/biochar as a low-cost origin of potential adsorbent is extensively discussed.
