ARIPPA is a not-for-profit trade association comprising thirteen independent power producers in Pennsylvania that generate approximately 831 megawatts of electricity by using environmentally-friendly Circulating Fluidized Bed (CFB) boiler technology to burn coal mining refuse.

Hundreds of millions of tons of unusable coal mining wastes (called "culm" in the eastern Pennsylvania anthracite region and "gob" or "bony" in the western Pennsylvania and West Virginia bituminous coal mining regions) have long imposed an environmental burden on the land.

Now, through the use of CFB technology, this "coal waste" is converted into electricity in an environmentally responsible way. Moreover, the unsightly refuse piles and the problems associated with them are gradually disappearing.

At the same time, thousands of acres of land are being reclaimed for productive use and turned into wildlife habitat or into future development sites.
