BIOMASS ENERGY | The renewable energy

Biomass is the fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power.”


“Biomass is biological material derived from living, or recently living organisms. In the context of biomass for energy, this is often used to mean plant based material, but biomass can equally apply to both animal and vegetable derived material.”


Biomass is carbon based and is composed of a mixture of organic molecules containing hydrogen, usually including atoms of oxygen, often nitrogen and also small quantities of other atoms, including alkali, alkaline earth, and heavy metals.These metals are often found in functional molecules such as the porphyrin which include chlorophyll which contains magnesium.

Categories of biomass materials:-

Within this definition, biomass for energy can include a wide range of materials.

There are five basic categories of material:

1- Virgin wood, from forest arboricultural activities or from wood processing.
2- Energy crops:- high yield crops grown specifically for energy applications.
3- Agricultural residues:- residues from agriculture harvesting or processing.
4- Food waste, from food and drink manufacture, preparation and processing, and post-consumer waste.
5- Industrial waste and co-products from manufacturing and industrial processes.

Biomass is a renewable source of fuel to produce energy because:

-waste residues will always exist – in terms of scrap wood, mill residuals and forest resources; and
-properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops.


Biomass power is carbon neutral electricity generated from renewable organic waste that would otherwise be dumped in landfills, openly burned, or left as fodder for forest fires.

When burned, the energy in biomass is released as heat. If you have a fireplace, you already are participating in the use of biomass as the wood you burn in it is a biomass fuel.

In biomass power plants, wood waste or another waste is burned to produce steam that runs a turbine to make electricity, or that provides heat to industries and homes. Fortunately, new technologies — including pollution controls and combustion engineering — have advanced to the point that any emissions from burning biomass in industrial facilities are generally less than emissions produced when using fossil fuels (coal, natural gas, oil). Re-Energy has included these technologies in our facilities.

ADVANTAGES of Biomass Energy:-

1) It’s a renewable source of energy.
2) It’s a comparatively lesser    pollution generating energy.
3) Biomass energy helps in cleanliness in  villages and cities.
4) It provides manure for the agriculture and gardens.
5) There is tremendous potential to generate biogas energy.
6) Biomass energy is relatively cheaper and reliable.
7) It can be generated from everyday human and animal wastes, vegetable and agriculture left-over etc.
8) Recycling of waste reduces pollution and spread of diseases.
9) Heat energy that one gets from biogas is 3.5 times the heat from burning wood. 10) Because of more heat produced the time required for cooking is lesser.

DISADVANTAGES of Biomass Energy:-

1)  The cost of construction of biogas plant is high, so only rich people can use it.
2)  A continuous supply of biomass is required to generate biomass energy.
3) Some people don’t like to cook food on biogas produced from sewage waste.
4)  Biogas plant requires space and produces a dirty smell.
5)  Due to improper construction, many biogas plants are working inefficiently.
6)  It is difficult to store biogas in cylinders.
7)  Transportation of biogas through the pipe over long distances is difficult.
8)  Many easily grown grains like corn, wheat is being used to make ethanol. This can have bad consequences if too much of food crop is diverted for use as fuel.
9)  Crops which are used to produce biomass energy are seasonal and are not available for the whole year.

Biomass is a very helpful source of renewable energy that’s come at the second number after hydro energy.
