ameliorate the soil quality, reduce fertilizer consumption, and sequestrate carbon. This study
compares the characteristics of biochar produced by slow pyrolysis at 500° C for agricultural
residues: sugarcane bagasse, cocopeat, paddy straw, palm kernel shell (PKS) and umbrella
tree. In the biochar yield, the influence of the inert and lignin contents was significant. The
wood stem, bagasse and paddy straw had biochar yields of 24–28 wt.% from the organic …
