Biochar characteristics

WebBiochar is a charcoal-like product that is created by heating biomass to very high temperatures in a low-oxygen environment—a process known as pyrolysis. Converting biomass to biochar slows the decaying process and locks stored carbon in place, in turn slowing down its release back into the atmosphere. [ 1] WebNov 1, 2024 · Biochar can be characterized by several features including large surface area, various functional groups and high porosity (Godlewska et al., 2024). Pyrolysis is the main process to produce biochar under limited supply of oxygen at varying temperature i.e. 200–1000 °C (Waqas et al., 2014, Khan et al., 2015b).
