FAQ

Biomass briquettes are a sustainable fuel alternative in India, made from compressed organic matter like agri waste. They are widely used for heating, cooking, and electricity generation, particularly in regions lacking access to conventional fuels. India has abundant biomass resources, making briquette production a promising path to cleaner energy.

What are biomass briquettes?

They are compact blocks of organic materials (like agricultural residues) that are pressed together and used as fuel.

The calorific value of the finished briquettes is approx 4000 k.cal/kg. The calorific value may vary depending on the different RM used. It can replace any kind of coal like lignite, firewood, steam coal etc

They are used for heating, cooking, and electricity generation.

They are a renewable, cost-effective, and environmentally friendly alternative to fossil fuels.

  • Briquettes are cheaper than coal.
  • Oil, coal or lignite, once used, cannot be replaced.
  • There is no sulfur in Briquettes, thus does not pollutes the environment.
  • Biomass briquettes have a higher practical thermal value
  • Briquettes have much lower ash content (2-10% as compared to 20-40% in coal).
  • Combustion is more uniform compared to coal
  • Briquettes are usually produced near the consumption centers and supplies do not depend on erratic transport from long distances.
  • Briquettes give much higher boiler efficiency because of low moisture and higher density.
  • Briquettes, are easy to store, pack and hygienic to handle.

Briquettes have high specific density (1200 Kg/m3) and bulk density (800 Kg/m3) compared to 60 to 180 Kg/m3 of loose biomass.

Biomass is often collected by farmers or biomass aggregators, who use methods like slashing, raking, and baling.

Briquettes are widely used for any thermal application where coal can be utilize i.e. steam generation in boilers, heating purpose etc.
briquettes can replace following conventional fuels that are used in mass quantities:

  • Diesel
  • Kerosene
  • Furnace Oil
  • Lignite
  • Coal
  • Firewood

Following industries can make maximum use of briquettes

  • Ceramic and Refractory Industry
  • Solvent Extraction Plant
  • Chemical Units
  • Dyeing Plants
  • Milk Plants
  • Food Processing Industries
  • Vegetable Plants
  • Spinning Mill
  • Lamination Industries
  • Leather Industries
  • Brick Making Units
  • Other Industries having Thermal Applications
  • Gasifier system in Thermal
  • Textile Units

While biomass briquettes are generally considered more environmentally friendly than fossil fuels, burning them can still contribute to air pollution, especially with poor combustion.

Very low ash content as low as 3 to 8% compared to 20% to 40% in coal.
