Potential of Biochar Derived from Agricultural Residues for Sustainable Management

A horizontal drum kiln is a traditional method widely used in Southeast Asian countries for producing biochar. An understanding of temperature conditions the and its influence on biochar properties crucial identifying suitable applications. In this study, four agricultural residues (corncob, coconut husk, shell, rice straw) were production. The turned into within 100–200 min, depending their structures. suitability briquette fuels was analyzed using proximate, ultimate, elemental analysis. biochar’s physical chemical characterized via bulk density, iodine number, pHpzc, SEM, FTIR measurements. All biochars had low O/C H/C ratios negative charge from both carbonyl hydroxyl groups. Coconut husk shell desirable such as high heating value amount surface functional groups which can interact with nutrients soil. These are thus use variety purposes including biofuels, adsorbents, soil amendments.
