Biochar refers to any material that has transformed into an amorphous, graphite-like structure as a result of the thermochemical conversion of organic materials. Incorporating biochar into soil contributes to mitigating the effects of climate change through the sequestration and storage of carbon. There are numerous methods for producing biochar, including pyrolysis, gasification, hydrothermal carbonization, and flash carbonization. The choice of technology largely depends on the intended use of the biochar and the type of biomass available. However, traditional production processes often face environmental challenges, especially in developing countries. This study introduces several traditional charcoal-burning techniques used around the world and provides an overview of modern industrial biochar production methods. International organizations have developed standards for determining the quality parameters of biochar and have proposed guidelines for its application in soil. According to the available literature, biochar presents a promising opportunity for advancing sustainable agriculture and mitigating climate change.
