Biomass is a type of material from living organisms that mainly referring to plants or plant-derived material. It could convert to other types of energy through combustion, chemical reaction or biochemical conversion which makes biomass energy become a kind of renewable energy. In many ways biomass can be considered as a form of stored solar energy. The energy of the sun is captured through process of photosynthesis in growing plants.
There are three different types of biomass material according to the IEA:
- Woody biomass: Forest residues, Fuel wood, Short rotation forestry, Woodlands biomass.
- Non-woody biomass: Agricultural crops, Crop residues, Processing residues.
- Other organic wastes: Animal waste, Sewage sludge, Organic wastes produced by households and institutional buildings.
As a fuel, biomass sources could produce energy through
Combustion,
Gasification,
Pyrolysis and
Anerobic Digestion. Biomass technology might have impact on the environment when the main methodology is combustion which would emit a large amount of Carbon dioxide to the atmosphere. Furthermore, it also has an impact on the land conservation.
