Abstract

Biochar is a useful method of converting what is known as typical either from municipal waste or agricultural waste into something that can be used that is actually beneficial to mankind. With the help of pyrolysis process it is possible to convert such waste into biochar and provide great application in preserving the environment, as well as to reduce the carbon emission to the atmosphere. In this review paper, production methods on biochar such as slow pyrolysis, fast pyrolysis, torrefaction, gasification and hydrothermal carbonization are reviewed and compared. Modifications of biochar in accordance with its respective activation are reviewed and compared through the means of physical and chemical. Various applications of activated biochar that are useful in helping the environment by treatment of heavy metals organic and microbes by the means of adsorption, catalyst, soil amendment are reviewed.
