Coal-fired power plants in the United States generate about 75 million tons of coal ash annually. Compared with the 267 million tons of trash that Americans generate per year, it
Bauxite is a sedimentary rock that is rich in alumina, the base for making aluminum. It is generally easy to mine because it is found near the surface of terrain.

Fly ash is the mostly mineral residue left over from burning coal by coal-fired power plants. Fly ash is pozzolanic, meaning that it has cementitious properties that make it valuable
According to a report from the Energy Information Administration, operating margins for corn-based fuel ethanol plants decreased to a multi-year low in 2019. This was due in part because production
