chemical feedstock for various purposes such as energy production, and adsorption of
pollutants. In particular, application of biochar to the soil is gaining greater interests, which
can reduce fertilizer consumption, increase crop yields, and sequestrate carbon. This study
compares the characteristics of biochar produced by slow pyrolysis at 500° C for five
biomass residues from Indonesia: sugarcane bagasse, cocopeat, paddy straw, palm kernel …
