By definition, briquettes are solid fuels made from carbonaceous waste that have a high calorific value and can burn for a long time. The production of briquettes is inextricably linked to pulverised biomass. Biochar itself is the result of burning dry biomass without direct exposure to air. Meanwhile, biomass is organic material derived from fossils. Biomass can actually be used directly as heat energy for fuel, but is less efficient, biomass has a calorific value of only 3000 cal, whereas biochar has a higher calorific value of 5000 cal
