Biomass Energy

One of the sources of renewable energy is Bioenergy or Biomass Energy , which comes from the sun and is used by both animals and plants, through the process of photosynthesis that converts organic matter into a very powerful type of energy to satisfy human needs.

What is Biomass Energy

It is that energy that is obtained through a biological process, both natural or artificial, of the use of organic matter ; that is to say, of the residues or remains of the biodiversity of living beings such as plants, animals or other organisms .

What is the Origin of Biomass Energy?

This arises with the energy that comes from the sun , which is absorbed by the plants in the process of photosynthesis and subsequently converted into organic matter for the production of heat, energy and biofuel .

It is the oldest renewable energy source that man has used until the arrival of fossil fuels and currently plays a fundamental role in the face of the energy crisis .

This biomass energy produces more than 2 · 1011 tons of dry organic matter per year and is five times the world’s energy demand .

What are the Biomass Energy Characteristics

  • First source of renewable energy used by mankind.
  • It is a biological and ecological system.
  • Diversity of shape, size and variable according to its typology.
  • It has calorific value, content and melting temperature of ashes.
  • Organic matter is its main source of energy.
  • It is mainly based on plants, trees and animals.
  • It produces thermal and electrical energy.
  • Its main products are biofuels, biodiesel, bioethanol, oil and biogas
  • It is not a completely clean energy source, but with fewer emissions.
  • Respect the conservation of the environment.
  • It is sustainable and enduring over time.

How Biomass Energy Works

This energy is produced by the direct combustion of organic waste for the transformation of biofuels and energy .
This same one, is processed in boilers where the material is burning and generating ashes that can then be used as fertilizer .

Likewise, by a thermo-chemical process where biomass is transformed into fuel by means of a pyrolysis or carbonization process and finally by the bio-chemical process , where biomass in an environment is moistened in bacteria to obtain gas by Medium of a biodigester .

What are the types of biomass

Biomass can be classified as follows:

Natural biomass; Without the hand of man, for example, fall trees, pruning of forests, thickets, crops, others.

Residual biomass; waste that is generated in the activities:

  • agricultural
  • forestry and livestock
  • agrifood industry
  • wood processing industry
  • wastewater treatment plants and oil recycling

Energy crops; those destined to the production of biofuels, bioethanol and ole.

What are the Uses of Biomass Energy

  • Electricity generation
  • Heat generation
  • Heating systems
  • Steam generation
  • Biofuels
  • Others

Advantages and Disadvantages of Biomass Energy


  • It is renewable
  • Transition and useful energy
  • Less CO2 and sulfur emissions
  • Insect pests are reduced
  • Minimize the risk of fire
  • Provides energy as an alternative to fossil fuels
  • Employment generation
  • Contributes to the culture of recycling and sustainable development
  • Promotes a better quality of life


  • Higher production cost
  • Toxic substances
  • Use of edible vegetable crops and crop change on land
  • Lack of uniformity and its low density
  • Less performance than other energy sources
  • Alter commodity prices
  • Large spaces are needed
  • Ecosystem disruption

Examples of Biomass Energy

  • Firewood
  • The grey hair
  • Leftovers
  • Seeds and nutshells
  • Beet, corn, wheat, sorghum, barley and other cereals
  • Sawdust
  • Livestock waste
  • Pellet
  • Biodiesel
  • Others


Definitely, biomass energy is the best alternative to harness the energy of domestic, industrial, agricultural, agricultural, forestry, commercial, urban remains or waste from animals and plants to generate heat-electricity.

However, it is not a source of clean energy because ashes and gases are generated to obtain it, but it is the best option for fossil fuels .

In summary, plants absorb the sun’s energy , transform it into chemical energy through the process of photosynthesis ; it is recovered by burning it directly or transforming it into fuel and electricity to meet the basic needs of humanity
