The Magic of BriquettingBriquetting is the almost magical process of compressing the loose biomass into a compact form called as fuel briquetttes or “BIOCOAL”.
Briquetting achieves up to 90% reduction in volume, while giving a shape to biomass. The form change results in a much higher specific density of the material, which increases its combustion efficiency. It makes the Biomass a great fuel! while giving a shape to Biomass thus storage, transportation & handling costs reduces by almost 10 times, making it much easier to store and transport than loose biomass waste. Other fuel types tend to be difficult to handle and are hazardous. Briquettes can be produced in a variety of sizes and have a long shelf-life as compared to the loose material.
PollutionBriquettes are immeasurably cleaner than the other fuel alternatives - especially coal! because They do not emit any harmful substances like SO2 or nitrogen oxide during combustion. The direct burning of loose biomass in conventional grates is associated with very low thermal efficiency and widespread air pollution. The conversion efficiencies are as low as 40% with particulate emissions in the flue gases in excess of 3000 mg/ Nm3. In addition, a large percentage of un burnt carbonaceous ash has to be disposed of. In the case of rice husk, this amounts to more than 40% of the feed burnt. Most of this biomass goes to waste by being dumped into land fills and even burned, which causes air pollution. Instead of making use of the precious land that we have and polluting the air, we can use biomass to create energy and fuel, as well as feed and other agricultural necessities.
Dust pollution associated with direct combustion of loose biomass can be avoided switching over to Briquettes. Moreover the chance of fly ash is minimizes when Bio Coal Briquettes are burnt.
Considerable reduction of fine dusts and other wastes through compression of the material, into clean and compact briquettes. Reduction in the danger of fires and explosions by briquetting flammable waste the economic solution to costly fire prevention measures.
EfficiencyUniform physical dimensions & combustion characteristics, results in more efficient energy conversion. Briquettes burn in a controlled manner, slow and efficiently because of lower moisture content, higher bulk density, & lower ash content. More and more, utility Industries are using biomass briquettes to supplement or replace coal as a solid fuel source. Biomass briquettes can be used in almost any type of existing combustion grates.
CostThe purchase price of biomass briquettes is less than ,Coal , Fire wood. The " Biocoal "made from Infinite Little Master have uniform thickness, density and calorific value. This makes them suitable for use in a diverse range of applications. Biomass Briquettes offer many benefits over traditional fuels like Coal, Wood Chips, Green Wood, Nut Shells, Rice Husk and various husks, fines and fibers.
Quality & Clean FuelBiomass Briquettes has consistent quality & it is very clean to handle.

All plants, including those from the sea and other water bodies, are considered to be biomass. Though, usually, the term refers to what they leave behind that we do not use for food or materials. For example, straw, corncobs, husks, animal waste, garbage, and other things that we usually throw away and forget about.
These materials are not useless, as most people believe them to be. Although they are the left-over pieces from industrial processes and natural waste, they can be used for many different uses. And though most people wouldn't think it, these are the key to creating a better world and a better future.
Biomass is all of the matter which is organic, contains carbon, and has gone through photosynthesis and other processes. Biomass is mostly made up of plants which make use of the light from the sun to create energy through photosynthesisMany of the developing countries produce huge quantities of agro residues but they are used inefficiently causing extensive pollution to the environment. The major residues are rice husk, coffee husk, coir pith, jute sticks, bagasse, groundnut shells, mustard stalks and cotton stalks. Sawdust, a milling residue is also available in huge quantity. Apart from the problems of transportation, storage, and handling, the direct burning of loose biomass in conventional grates is associated with very low thermal efficiency and widespread air pollution. The conversion efficiencies are as low as 40% with particulate emissions in the flue gases in excess of 3000 mg/ Nm In addition, a large percentage of un burnt carbonaceous ash has to be disposed of. In the case of rice husk, this amounts to more than 40% of the feed burnt. Most of this biomass goes to waste by being dumped into land fills and even burned, which causes air pollution. Instead of making use of the precious land that we have and polluting the air, we can use biomass to create energy and fuel, as well as feed and other agricultural necessities.
Biomass is definitely a great way to help fix our earth. It is completely natural, and we can use it for fuel biomass, and many other things. There are many ways that we can get this biomass and use it to its full capacity. First of all, we should collect the residue that comes from agricultural and forestry processes. This can be used for manure, fuel, and even feed stock. Industrial waste such as used fuel can be reused to create more fuel that can be used in other fields.
The great thing about biomass is that it can be grown for our needs. Growing plants to use as biomass will not only give us biomass to use, but it will also help clean out our land and air resources.
There are many different uses of biomass, and one of the most popular is as a fuel . Biomass can create gas fuel and liquid fuel if it goes through processes. Biomass can be compressed so that it can be burned efficiently to create heat for cooking and heating. Also, biomass can be fermented in order to create liquid gas which can be used for cars and other vehicles.
ConceptThe process of "BRIQUETTING" is the physical transformation of the loose raw material into a compact form. The form change results in a much higher specific density of the material, which increases its combustion efficiency as compared to the loose material. Briquetting (compacting)the Biomass , for fuel biomass is one of the simplest forms of using biomass. The residue left from crops and harvesting can be used as fuel biomass. This way, none of it goes to waste .
Briquetting of the husk could mitigate these pollution problems while at the same time making use of this important industrial/domestic energy resource. Moreover ,Loose production waste such as dust or shavings represents a considerable cost factor. By compressing this waste material into briquettes we can decrease costs while reducing the mess and increasing safety
By briquetting waste materials, volumes can be reduced by up to 90%. This creates a significant savings on transportation/handling/storage costs for later use as a heat source or simply for more convenient disposal. An additional advantage comes from briquetting flammable waste materials such as fine dust particles that are often created from wood processing operations. Briquetting eliminates the dust from the air and the mess created when removing dust collection bags, further reducing the risk of sparks or fire.
In addition to this commercial aspect, the importance of this technology lies in conserving wood, a commodity extensively used in developing countries and leading to the widespread destruction of forests.
TechnologyBiomass densification, which is also known as briquetting has been practiced for many years in several countries. In Japan sawdust briquettes,are known as 'Ogalite', 'Prest-o-log' technology of the United States, the 'Glomera' method in Switzerland and the 'Compress' method in West Germany. At present two main high pressure technologies: ram or piston press and screw extrusion machines, are used for briquetting. While the briquettes produced by a piston press are completely solid, screw press briquettes on the other hand have a concentric hole which gives better combustion characteristics due to a larger specific area.
The screw press briquettes are also homogeneous and do not disintegrate easily. Having a high combustion rate, these can substitute for coal in most applications and in boilers, Gasifiers etc

Manufacturing ProcessFuel briquette is black / brown in colour.. When agro-waste of cellular nature is briquetted, it produces low cost, high calorific value fuel which can from a good substitute for wood and coal. This implies conversion of waste into a useful energy source. The end product has the following typical proximate analysis :-
- Waste materials are tested for their chemical composition to decide on their suitability and to select a proper mix.
- Dried Biomass material containing approximately. 10 - 15 % moisture is suitable for briquetting. However if material has higher moisture content it needs to be dried (through dryer or sun dry) before use.
- Material is screened, chopped and ground to get the desired size and bulk density and is pneumatically transported into storage bins. This helps in separation of the heavier and metallic particles and also unifying moisture content in the material. Air used is hot or wet as the case may be, for control of moisture. ln this process the cellulose bonding in biomass collapses due to application of high pressure (1200 kg/sq.cm), and temperature (200 o C) & more thereby fluidizing the lignin.
- The moisture content in the material should be lesser than 12% for best results during compaction. Material from bin is discharged to the machine through regulated conveyors where it is compressed in specially designed dies. The compression raises the temperature of the material, softening some of the inherent binders in it, which come to the surface and bind the material together.
- Briquettes formed are in the shape of logs or pellets, which are forced through tracks for proper shaping, by cooling them under pressure.
- Cooled briquettes are cut and packed in bags or stored in bulk for shipment or use.
- No Binder is required in the process.
