The various uses of biochar in construction as a potential carbon sink application. Biochar can be used as a cementitious additive in concrete and mortar. The potential for incorporating biochar into bricks has been recognised due to biochar's thermal insulating qualities when used in place of sand and aggregates, as well as its direct impact on weight reduction and carbon dioxide removal from the atmosphere. Finally, biochar has the potential to be used as an asphalt additive and to be incorporated in biocomposites for enhanced insulation, moisture regulation and electromagnetic radiation protection
