This project is called White Coal Plant and is a process of converting Agro waste and forestry
waste into biomass briquettes/Bio coal. The biomass briquetting is the best renewable source of energy for
healthy environment and economy. Its complete Eco-friendly green energy project.
We all are well aware with the importance of energy and its sources. Energy is the key factor in the
economic development of every country. The demand of energy is increasing day by day and the supplies of
sources are limited. It is globally red alert for fossil fuel like petrol, kerosene, natural gas, LPG and lignite
etc. this has made a huge gap between demand and supply of energy. Renewable energy is the ultimate
solution, which can fill this gap. Most of advanced countries have adopted this concept and accepted this
project and have retained their natural resources to get the solution of energy and fuels.
Main concept of this project is to produce the material as a bio-coal, which is made from the wastages. We
cannot destroy the wastages totally but we can use it with the help of briquetting plant and can produce the
briquettes which ultimately generate energy. To provide the energy in low cost is the main concept of the
Almost any biomass can be briquetted. Briquetting plants set so far in India are using saw dust, bamboo
dust, bagasse, cotton stalk, coffee husk, groundnut shell, mustard husk/stalk, pine needles, rice husk, sugar
mill waste, jute waste, coir pith and other wastes & residues like castor shell, tobacco stem, tea waste, tree
bark, wild grasses & shrubs i.e. any type of agriculture waste or forestry waste can be also briquetted
individually or in combination without using any binder.
Raw material like saw dust is screened and stalk (Forest & Agro waste) are chopped by cutter chipper
cum grinder (Single action) if the raw material size is bigger than 25mm.
For using material of two or more types, it should be mixed in suitable form.
If raw material has high moisture then it should be reduced by sun drying or using turbo dryer.
Normally if the moisture level is higher than 15% there would be a requirement of dryer.
Raw material (of desired size) is transported by pneumatic system to holding bins fixed over
By screw conveyor, material moves from bin to the press.
Material is compressed by ram through taper bored die. By compression temperature is raised & lignin
come to the surface and binds the material by its natural binder.
Briquettes are formed in shape of log and it is automatically pushed through cooling line to the storage
