► Hydrothermal carbonization was employed to upgrade fuel quality of waste biomass. ► The improved fuel qualities of the biochars are similar to those of lignite. ► Hydrothermal carbonization narrowed the differences among different biomasses. ► The biochars have the potential to be used as a coal s...
