Torrefaction is considered environmentally friendly due to its ability to enhance the fuel properties of biomass while reducing emissions of pollutants. The process also contributes to the sustainable management of biomass resources by improving their efficiency as a renewable energy source. However, the environmental impact of torrefaction must be assessed on a case-by-case basis, considering factors such as the source of biomass, energy consumption during the process, and the fate of byproducts.
