Biochar formulation using alkaline pre-treated oil palm trunks and oil palm frond

Biochar is charcoal made from plant material and agricultural biomass. The biochar is produced by slow thermo-chemical pyrolysis of biomass materials and has been proven of its benefits in soi l enrichment and as a combined material for industrial heat ing fuel. In the present research, biochar formulation was made to utilize two types of oil palm t ree biomass; oil palm t runk (OPT) and oil palm frond (OPF). The best combination of both materials was evaluated in terms of calorific heat value, moisture and ash content and compared with the standard biochar. In addition, t reated OPT and OPF were compared with the untreated material to further enhance the characteristic of the biochar
