Biomass is defined renewable energy resources for the purpose of generating electrical energy as solid, liquid and gaseous fuels obtained from organic wastes as well as agricultural and forestry products, including vegetable oil wastes and agricultural harvest residues, and from by-products resulting.
Biomass is defined as wastes and residues, of unfossilized living creatures that lived underground, aboveground and in waters within a certain period of time, emerging as the origin of all organic substances and living organisms containing carbohydrate compounds.
Trees, specially-grown crops such as corn and wheat, herbs, seaweeds, marine algae, any organic domestic waste such as fruit and vegetable residues, animal feces, manure, and industrial wastes are examples of biomass. Biomass is recognized as a suitable and significant source of energy since it is inexhaustible, capable of being grown everywhere, and contributory to socio-economic development of rural areas.
