Biomass Energy: Pros And Cons


Biomass fuels have been utilised to create energy since time immemorial. Historically, humans used wood to provide heat for cooking and other uses. Coal-fired systems were adopted in the 1800s in major cities throughout North America and Europe. Consider the pros and downsides of biomass.

Advantages and Disadvantages of Biomass: Things to Consider

The discovery of other substantial sources of energy, such as coal and petroleum, altered the way energy is produced dramatically. However, due to the scarcity of fossil fuels, humanity have reverted to more primitive means of energy production, such as biomass.

Within living entities such as plants and animals, biomass exists. Additionally, it can take the shape of recently alive or deceased plants, grass, trees, leaves, crops, manure, rubbish, and animal wastes.

Biomass energy, sometimes referred to as bioenergy, is a type of renewable energy. Our sustainable energy community can assist you in weighing your alternatives.

Green Coast was intended to educate the public on how various renewable energy technologies interact, and hence these are a few points to consider regarding how biomass works.

Methods For Converting Biomass To Energy

Biomass may be converted into energy that can be used to power houses, buildings, hospitals, and shopping malls, among other things. There are various ways to convert biomass to energy, including the following:


Biomass energy is created when organic matter such as plants, agricultural and forestry leftovers, as well as municipal and industrial trash, is burned. It happens when heat is applied to organic matter in the presence of oxygen in a boiler, resulting in the production of steam.

The steam generated turns a turbine attached to a shaft, which in turn spins an electric generator.

The generated energy can be utilised for a variety of heating purposes. When carbon dioxide is burnt, it is discharged into the atmosphere.


Gasification is the process of converting organic matter into gaseous products such as carbon monoxide, carbon dioxide, and hydrogen. To do this, organic compounds are heated with a small quantity of oxygen and without combustion.

It produces a gas combination known as syngas or producer gas, which is also a kind of fuel.


Pyrolysis is a Greek term formed from the Greek terms pyro and lysis, which represent fire and separation, respectively. It is the process of degrading organic matter by subjecting it to extremely high temperatures in the absence of oxygen.

Because no oxygen is utilised, the organic material does not burn but decomposes into three forms: syngas, liquid bio-oil, and solid bio-char.


Bio digestion, sometimes referred to as anaerobic digestion, is a process in which bacteria degrade organic matter in the absence of oxygen to produce biogas.

The biogas is combustible and used to create electricity.


Fermentation is another technique that includes turning sugar from an organic substance to alcohol or ethanol using yeast. The ethanol produced can be used to fuel cars.

Thus, what are the benefits of biomass?

Let us begin.

The Benefits of Biomass Energy

Numerous advantages exist for biomass energy, including the following:

Renewable energy sources

Due to the way biomass energy is generated, it is a renewable resource. To generate energy, organic matter such as crop waste, wood, and other particular resources is grown. It is derived from inexhaustible natural resources and waste products that we produce on a continuous basis.

The majority of biomass energy comes from sewers, waste, manure, sludge, and other kinds of organic matter. Today’s biomass is renewable, and a fresh crop can be planted following each harvest, making it conveniently and widely available.

Additionally, organic byproducts such as biochar are produced as a result of biomass use.

Carbon Neutral

The question of whether biomass is carbon neutral or not has sparked debate and a point of controversy among several industries. Carbon dioxide, a greenhouse gas, is emitted into the atmosphere by fossil fuels.

Biomass is a superior and more dependable option since it is a low carbon fuel that emits less carbon dioxide.

Reduces Amounts Of Organic Wastes In Landfills

An additional key benefit of biomass fuel is that it aids with waste management. The bulk of garbage generated on homesteads is biodegradable or composed of plant stuff.

Biomass repurposes this type of waste, hence reducing the amount of organic waste in landfills and the associated negative consequences on the environment, habitat, and animal ecosystem.

Reduced waste also means more space is available for alternate purposes.

Increased Efficiency And Less Reliance On Fossil Fuels

Additionally, biomass fuel is an excellent substitute for fossil fuels. The use of trash to generate energy results in a decrease in the consumption of fossil fuels.

Due to the scarcity of fossil fuels and the high cost of extraction, biomass energy is a great option.

Can Be Used In Many Forms And Create Different Products

Different types of biomass may be utilized to produce a variety of biofuels, including methane gas, biodiesel, and others. These items are utilized as energy sources and have a variety of uses.

Biomass may also be utilized to create power by heating steam turbines.


Another key advantage of biomass energy is its lower cost of operation in comparison to coal and oil. It costs a third less to complete the same task with fossil fuels.

Biomass’s Disadvantages

While biomass offers several advantages, it also has a number of disadvantages. Among the downsides of biomass fuel are the following:

Emits Noxious Gases Into The Atmosphere

As with other solid fuels such as coal, burning biomass results in significant pollution emissions. Thus, biomass energy has the potential to be a large source of air pollution. Biomass energy produces methane emissions that deplete the earth’s ozone layer and contribute to global warming.

Additionally, burning organic waste releases particulate matter (PM), carbon monoxide (CO), nitrogen oxides (NOx), sulphur dioxide (SO2), mercury, and lead, as well as other hazardous air pollutants (HAPs) such as styrene, acrolyne formaldehyde, hydrochloric, and hydrofluoric acids.

The HAPs, a collection of 187 toxicants, are claimed to be a leading cause of cancer, as well as other major health, reproductive, and birth consequences, as well as environmental implications.

Risk Of Deforestation Is Increased

Uncontrolled biomass production may result in the loss of trees as humans seek additional wood for biomass energy conversion. Deforestation may have devastating consequences for both animals and humans, as well as their habitats and ecosystems.

It may result in less rainfall, which may result in drought and famine. It is critical to have effective biomass production management methods in place to aid in the preservation of trees.

Inefficient Compared To Gasoline

When used in combustion engines, biodiesel products such as ethanol must be blended with gasoline. Additionally, prolonged usage of ethanol might have a detrimental effect on the engine.

Producing Biomass Energy Needs a Significant Amount Of Room, Money, And Work.

The cost of setting up a biomass energy plant is fairly high, and it requires a lot of room. Transportation and other resource acquisition costs are relatively expensive. Energy plants still require fuel as a resource in the generation of biomass energy.

The bulk of energy boilers is located in metropolitan areas, which results in increased traffic and pollution, which appears to be more of a problem than a solution.

Biomass energy generation is still in its infancy, and considerable time and effort have been invested in making it more effective and efficient.


Without a doubt, the advantages of biomass energy outweigh the downsides. Thus, it is one of the finest alternatives to fossil fuels and will almost certainly be enhanced and used more in the future.
