Different Ways of extracting energy
from biomass
The different methods of biomass extraction can be broadly be
classified as:
a) Anaerobic Digestion.
b) Gasification.
c) Liquefaction.
Solid fuel combustion
a) The simplest and most common way of extracting energy
from biomass is by direct combustion of solid matter.
b) Majority of the developing countries especially in rural
areas obtain the majority of their energy needs from the
burning of wood, animal dung and other biomass. But
burning can be inefficient.
c) An open fireplace may let large amounts of heat escape,
while a significant proportion of the fuel may not even get
burnt.
