Abstract

The study examines the impact of kiln capacity on environmentally friendly biochar yield and characteristics from rubberwood scrap using an MCGB as the heat source. A 600-liter finned-wall kiln was tested at 50 %, 75 %, and 100 % capacity. The MCGB maintained 550 °C for pyrolysis, with an equivalence ratio of 0.3–0.6 (gasification) and 0.7–0.9 (combustion), a peak temperature of 1204 °C. The biochar yield was 26–27 %, while wood vinegar yield ranged from 38.1 to 42.5 %. The kiln reduced pyrolysis time by 55 % compared to conventional klin, with GHG emissions of 0.16–0.21 kg CO2e/kg-biochar. The biochar met cooking and deodorization standards, highlighting the MCGB's efficiency and sustainability.
