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:
- 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
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
- The grey hair
- Seeds and nutshells
- Beet, corn, wheat, sorghum, barley and other cereals
- Livestock waste
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
