The development of green fuel and energy technologies has attracted a great deal of attention in that it can lessen fossil (nonrenewable) fuel consumption, abate greenhouse gas emissions, and mitigate global warming and climate change for resource and environmental sustainability. Torrefaction is a promising thermochemical conversion process to pretreat and upgrade biomass for its further utilization. After undergoing torrefaction, the disadvantages of biomass such as hygroscopic and biodegradable nature, high moisture content, low calorific value, poor grindability, large volume or low bulk density, and low homogeneity for industrial usage can be solved, making biochar approach coal. As a result, torrefied biomass can be used as an alternative to coal consumed in the industry. This study addresses the advances in biomass torrefaction technology to produce biochar for green fuel and energy. The applications of torrefied biomass in the industry such as combustion, gasification, ironmaking, pyrolysis, and liquefaction are also underlined.
