Abstract:  Biochar is generally produced through pyrolyzing of organic feedstocks in limited oxygen atmosphere. Though high demand for biochar, due to the hazardous smoke generation, cottage scale biochar production is still not popularized. Cottage scale operators produce biochar through primitive traditional techniques, resulting in high smoke emission and lower quality products. Coconut shell charcoal is the major biochar variety in Sri Lanka, mostly used as a raw material for activated charcoal. Large-scale producers use additional firewood kilns to secondary burn the generated smoke from biochar production. The retort technique is one of the suitable methods; however, it is not adopted by cottage scale producers due to its capital intensiveness. This study introduces a cottage scale LP-Gas fired kiln to produce high quality biochar material with less moisture content, compared with traditional methods. The proximate analysis of coconut shell charcoal showed high fixed c...
