Bio coal/ white coal or saw dust briquette are non-conventional source of renewable energy made by pressing agriculture waste under high pressure & contains no external chemical or binding material. Due to its clean energy (does not emit any green house gases), high density, low ash & high thermal efficiency, its being used as substitute to coal, wood furnace oil, etc. by industry.
