The concept of energy biomass includes materials of biological origin that cannot be used for food or industrial purposes. The possibilities of energy use of biomass are very different and are closely linked to the possibility of other uses of wood and agricultural waste as raw material, food or recyclable material. The average production rate on land is 7.6 x 1013W. Live biomass per unit area is small in the oceans and large in tropical forests. The amount of solar energy stored in the biosphere in the form of biomass is approximately 1.5 x 1022 J, which is equivalent to an average production rate of 1.33 x 1014 W. With this conversion process, solar energy is transformed into chemical energy that accumulates in different organic compounds and is incorporated and transformed by the animal and plant kingdom that, in turn, transforms it through artificial procedures to obtain consumer goods. The energy that can be obtained from biomass comes from sunlight, which, thanks to the process of photosynthesis, is used by green plants through chemical reactions in living cells to take carbon dioxide from the air and transform it into organic substances. Its development is closely linked to agricultural and forestry activities and the waste they produce. All this set has as a common denominator that organic matter comes, directly or indirectly, from the process of photosynthesis, which is why it is presented periodically and not limited in time. In a generic way, biomass means any mass of renewable living material present in an organism or organisms, including part of inert material, such as hair and feathers of vertebrates or the pulp of trees. Although its name suggests the opposite, biomass was the first fuel used by mankind.
