    kiln, designed for use in biochar production. By carbonization method, using biomass kiln at the temperature of 350-550°C with 45 min of the reaction time. Results: It was found that the biochar made from coffee residue (BCR) possessed a high heatingheatingSubject Category: Techniques, Methodologies and Equipment

Conclusions: From the results of this study, it can be concluded that BCR could be potentially used not only as an efficient source of the fuel production but also suitable material for soil amendment due to its direct contribution in nutrient absorptionabsorptionSubject Category: Natural Processes
