Before proceeding to determine the Meaning of the term biomass, it is necessary that we know its etymological origin. In this case, we can determine that it is a word of Greek origin since it is the result of the sum of two components of that language:
-The noun “bios”, which can be translated as “life”.
-The word “madza”, which is synonymous with “dough”.
The DigoPaul recognizes two great meanings of the term biomass. On the one hand, the concept refers to organic matter that is generated through a biological process (whether induced or spontaneous) and that can be used to produce energy. On the other hand, biomass is the totality of the matter of the organisms that inhabit a certain place, which is expressed in weight per unit volume or area.
According to DigoPaul, the first meaning mentioned is the most popular, since it is used in the field of energy production. In this case, the idea is focused on biomass that can be used for power generation.
The radiant energy of the solar rays, upon reaching our planet, is absorbed by plants. These living beings, through the process known as photosynthesis, convert said radiant energy into chemical energy. A portion of this energy is stored as organic matter: this biomass can be processed to take advantage of the energy and transform it into fuel.
In addition to all the above, we cannot ignore the existence of two types of biomass fundamentally:
-Residual biomass. Within this category are forest residues, agricultural, livestock, urban residues…
It is no less relevant to know that, in recent years, there has been a commitment to strongly boost biomass. This is due to a series of factors that have led to it, among which the following stand out:
-Remarkable climate change is taking place.
-The price of oil is getting more expensive.
-There has been an increase in agricultural production and it is necessary to find alternative uses for it.
-From the different governmental spheres, they are betting on giving aid and subsidies to those who dare to produce biomass.
Among the main advantages of biomass we can highlight the following:
-It is a type of energy of renewable origin, that is, it comes from what are sources that are not only natural but also inexhaustible.
-It becomes a great tool to promote forest cleaning.
-It does not pollute and, in addition, it is absolutely respectful with the environment.
It must be taken into account that biomass is not only the part of organic matter that can be used to produce energy: there is also biomass that serves as fertilizer or that can be used as food. It is also important to consider that the link between biomass and useful energy varies according to different factors.
The simplest method of obtaining energy from biomass is direct combustion: for example, burning wood. The biofuels are also made using the energy present in the biomass, while the process is more complex.
