Fly ash emitted from the coal-fired power plant is the major contributor of the outdoor airborne particulate matters (PMs). Coal beneficiation, an industrial process to improve the quality of raw coal by removing ash-bearing components, can be a cost-effective sustainable and clean technology to reduce the emission of hazardous trace metals.

The environment ministry in May last year decided that it will no longer regulate the ash content of coal used by thermal power plants. It issued a notification that overturned its January 2014 regulation that made it mandatory for all coal-based power plants located 500 km or more from the pit-head or coal mine to use raw or blended or beneficiated coal with no more than 34 percent ash content.
