Rules of making charcoal
Ford cars. To make use of the waste wood generated by the sawmill, a chemical plant was constructed and in operation by 1924. The chemical plant reclaimed, from every ton of scrap wood, a variety of saleable byproducts. The 610 pounds of charcoal reclaimed per ton was manufactured into briquettes and sold as Ford Charcoal.

As Enforcement Lags, Toxic Coal Ash Keeps Polluting U.S.
Over the last century, U.S. coal-powered electricity generation has produced at least 5 billion tons of coal ash, enough waste to fill a line of rail cars reaching the moon. Nearly 60 percent of U.S. annual coal ash production was recycled in 2021, mostly for cement and concrete, according to the American Coal Ash Association.

Coal Ash Basics | US EPA
Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coal-fired power plants. Coal ash includes a number of by-products produced from burning coal, including: Fly ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.

Sustainable ceramics derived from solid wastes: a review
Granite dust waste is produced in the rock mining during blasting and crushing of rocks. It is retained a high amount of SiO 2 and Al 2 O 3 with some amount of fluxes (Na 2 O & K 2 O) and coloring compound (Fe 2 O 3) [Citation 75]. So far, this waste can also be considered as alternatives for the conventional raw materials of ceramics.
