ABSTRACT
In recent years, with the development of society, there has been significant interest in the utilization of renewable bioresources such as biochar. After the green revolution, the increase in the production of biomass has generated a wide approach for the development of the bioeconomic sector by taking an account of the research activities on the production of biochar. Biochar is defined as a carbon-rich solid coproduct of pyrolysis. The generation of biochar from various waste materials by the process of pyrolysis plays an important role in materializing the circular economy. The unique properties of biochar make it a coherent, economical, and sustainable material for various environmental applications. The variableness in its physicochemical properties surface, such as pH and surface area microporosity, gives an approach for biochar to maximize its efficiency for its applications in various fields. Therefore, this review’s intent is to discuss the current trends on various techniques involved in the production of biochar from both the lignocellulosic and nonlignocellulosic sources. It further gives an outline of the physiochemical characteristics of the biochar resulting from various sources and its applications in the various fields.
