Visit any village and you will see women cooking over cow dung fired stoves, the air full of smoke and their eyes smarting. Now, imagine a scenario where they are cooking using wood or biomass, but there is no smoke and cooking becomes a pleasure. India has a huge rural population and there is an immense potential for briquettes that can be sold as a better alternative to wood or cow dung or any other form of fuel. Briquettes made in briquetting plants on the machines could also meet the needs of industries in cities. The business is highly profitable and with a reasonable investment you can expect steady, volume business that is expected to increase in upcoming years.

Overview of a briquetting plant

A typical briquetting plant comprises of the briquetting machines, a turbo dryer, a crusher-shredder and a powder making hammer mill. Raw materials used are groundnut husks, sugarcane bagasse, saw dust or rice husk or any agricultural waste. The process flow of a briquetting plant is as follows:

• The raw materials are put through a crusher to slice materials for the shredding process. The shredder reduces materials to even smaller sizes, applicable for woody branches, bagasse and similar products, turning them into powder ready to be fed to briquetting machine.

• If sawdust, rice husks or groundnut husks are used, then these are first sun dried to reduce moisture content to 12% or less.

• If the moisture content is high, the turbo dryer is used for quick drying.

• This powder is fed into a briquetting machine that employs a high power press to compress the powder into briquettes. High pressure generates high temperature and softens lignin in the cellulose, which then acts as a binder.

• The briquettes so formed are dried using torrefaction, pyrolysis or carbonization. This is essential if the briquettes are to burn without producing smoke.  The core of the briquetting plant is the briquetting machine.

A turbo dryer is optional if a manufacturer is assured of dry raw material like groundnut husks, saw dust or rice husk.

The smallest plant can output about 300 to 700 kgs briquettes per hour. Investment is easily recouped through sales and there is a ready market for briquettes. Given their advantages and if made available at a competitive price, briquettes could replace traditional fuels in rural scenarios. As such, it is a profitable venture and is absolutely recession proof.

There are other benefits of setting up briquetting plants using briquetting machines to manufacture briquette for fuel. State and Central government subsidies are available in addition to easy finance at low interest rate and long term repayment, accelerated depreciation, income tax holiday for five years and so on. Presently, there is less competition, but even if other Briquetting plants should come up, there will always be a huge market. Fuel is a necessity and if smokeless fuel is available cheaply at the same price as wood or coal, it will be an added incentive for more people to go in for briquettes.

Sanjay Tilala is an expert with a reputed organization dealing in manufacturing of Briquetting press machines. He has vast experience of decades in machinery manufacture and his special interest in generating renewable sources inspired him to branch out into manufacturing briquetting press manufacturing.
