To meet the global demand of energy requires an alternative source, preferably with a lower concern of climate change. Biochar production from agricultural biomass waste by pyrolysis creates a unique solution for producing a useful source of green energy. Biochar is a carbon-rich product with a high heating value which is comparable with our primary energy sources (fossil fuels). Biochar can be utilized for various purposes such as energy production and soil enhancement. Biochar can be more suitable for steelmaking, in view of their chemical and thermo-chemical characteristics including low ash, higher heating values (HHV), and high surface area. Biochar can also be utilised selectively for soil amelioration, C-sequestration, and waste water treatment, in view of the suitability of their characteristics (such as higher values of pH, mineral content, and surface area) for meeting the requirements for a particular purpose. This study associates the characteristics of biochar produced by slow pyrolysis at 800 °C for two biomass residues: corn cob and coconut shell. These results can be used to establish ideal utilization means of biomass for energy and/or biochar production.
