Reduce LOI Carbon Content
Fly ash is produced by coal powered power plants during the combustion of coal. In the past, fly ash was dispersed into the atmosphere along with flue gases. Environmental agencies created laws to reduce fly ash emissions so now more than 65% of fly ash produced from coal power stations is disposed of in landfills and ash ponds.
Increases in landfill and disposal costs prompted the recycling of fly ash in portland cement, bricks, cinder blocks and other building materials. Recycling fly ash also reduces the demand for virgin materials that would need quarrying or other materials that may be energy-intensive to create.
