Biomass can be generically referred to any plant or animal matter including all types of biofuel, but in this context what we mean by biomass is material like wood, which cannot be used for biogas generation with anaerobic digestion. These types of biomass could be directly used as burning fuel.
Sites with large amount of wood-type biomass are good candidates for alternative energy generation technology.
