Waste coal

From Global Energy Monitor

According to the Department of Energy, waste coal is "Usable material that is a byproduct of previous coal processing operations. Waste coal is usually composed of mixed coal, soil, and rock (mine waste). Most waste coal is burned as-is in unconventional fluidized-bed combustors. For some uses, waste coal may be partially cleaned by removing some extraneous noncombustible constituents. Examples of waste coal include fine coal, coal obtained from a refuse bank or slurry dam, anthracite culm, bituminous gob, and lignite waste."[1] Waste coal is referred to as "culm" in the Eastern Pennsylvania anthracite fields and as "gob" or "boney" in the bituminous coal mining regions.[2]
