This study explores the use of Areca spathe biomass, a by-product from plate manufacturing, as a feedstock for charcoal production. A 50-liter custom-designed kiln was developed with an adjustable combustion chamber and variable air perforation sizes (1.59, 3.18, and 4.76 mm) to optimize the carbonization process. Temperature sensors were integrated to monitor thermal distribution, while computational simulations modeled airflow and heat dynamics to enhance efficiency. Experimental results showed that the highest charcoal yield, 41.53%, was achieved within one hour using 1.59 mm air perforations. Simulations closely aligned with empirical data, showing only ±0.65% deviation at 552.11°C. The findings revealed that shorter carbonization durations generally increased yield by reducing over-decomposition; however, the relationship was not entirely linear. Extremely short times led to incomplete carbonization, while longer durations reduced yield due to carbon burn-off and ash formation, particularly in trials like ASB9. An optimal carbonization window was identified, balancing heat exposure to maximize yield without degrading the product. The optimized kiln produced high-purity, porous charcoal with low volatile content. While promising, further research is needed to refine operational parameters for consistent quality. This study supports sustainable development by enhancing energy efficiency, lowering production costs, and enabling potential applications such as activated carbon production and soil amendment. Additionally, it offers a viable model for community-scale charcoal production, providing both environmental and economic benefits.
