Abstract

Biochar is a carbon-dense material made by heating biomass in low or no oxygen ‎conditions. It is currently receiving attention for the many roles it can play. In this article, ‎we will introduce the main methods of biochar production, such as Slow Pyrolysis, Fast ‎Pyrolysis, Gasification, Hydrothermal, Carbonization and Torrefaction, and then explore ‎biochar applications in agriculture, construction, Energy Production and water treatment. ‎We will explore how biochar’s strong structure and unique chemistry can improve soil ‎health, reduce greenhouse gases, strengthen concrete, and trap pollutants in water ‎treatment systems. The article also points out existing barriers and points to future ‎research so that readers can gain a broad and balanced view of what biochar can still ‎achieve.‎
