Simple Method for Ficus Trees Trimming Biowaste Reuse in Production of Biochar as Soil Improvement Material for Drylands

Abstract Biochar was created using a simple low-cost kiln that was designed to process any biowaste. The kiln consisted of an inside cylindrical chamber of total capacity 0.272 m³. The temperature of pyrolysis may be raised to 550°C at a rate of 5°C per minute. We looked at five residence times (2,2.5,3,4, and 5 hours) to see how temperature affected the quality of the biochars. The surfaces of the generated biochars were measured for elemental compositions, chemical and physical characteristics, and elemental analysis. The production of trimmings from Ficus trees dropped as the pyrolysis temperature increased from 500°C. As the temperature of pyrolysis increased, the output of volatile matter also dropped. As the pyrolysis temperature rose, so did the ash content and fixed C in biochar from Ficus trees trimmings.
