Functional Group Structure of Bamboo and Pine Wood Biochar Due to Differences in Pyrolysis Temperature

open access: yesAceh International Journal of Science and Technology, 2022
The quality of biochar produced through the pyrolysis process depends on the combustion temperature, duration of combustion, and the raw materials used. Biochar is a carbon-rich product resulting from the thermal decomposition of organic matter.
