Biomass Valorization through Torrefaction for Biochar and Sustainable Materials

Environmental issues and resource exhaustion have become the biggest challenge to environmental sustainability. The developments of green fuel and sustainable materials have attracted a great deal of attention in that it can efficiently lessen fossil fuel consumption, prolongate resource lifetime, abate greenhouse gas emissions, and mitigate global warming and climate change, thereby achieving sustainable development goals (SDGs) of the United Nations. Torrefaction is a promising thermochemical conversion process to upgrade biomass or agricultural wastes for their valorization and further utilization. After undergoing torrefaction, the disadvantages of biomass or agricultural wastes 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 the produced biochar as a coal-like fuel. As a result, torrefied biomass can be used as an alternative to coal consumed in the industry. In this talk, recent progress in biomass waste torrefaction technology to produce biochar for green fuel and energy is addressed. The applications of torrefied biomass in the industry such as combustion, gasification, ironmaking, pyrolysis, and liquefaction are underlined. The produced products from torrefaction can also be used as sustainable materials such as reducing agents, bio-adsorbents, catalysts, etc. The advances of torrefied biomass for sustainable materials applications are also underlined..
