Abstract: Global warming has prompted a search for new materials that capture and sink carbon dioxide (CO2). Biochar is a derivative of biomass pyrolysis and a carbon sink mainly used to improve crop production. This work explores the underlying mechanism behind biochar’s electric conductivity using a wide range of feedstocks and its combination with a binder (gypsum). This gypsum–biochar composite exhibits decreased density and flexural moduli with increasing biochar content, particularly after 20% w/w. Gypsum–biochar drywall-like composite protot...
