Uncommon Energy Sources are used by manufacturers that are not usually used by other sectors, such as wood chips, bark, and wood waste materials produced during the preparation of wood pulping. The pulping process itself produces an energy source known as pulping liquor, which is also consumed as fuel. Other uncommon sources include blast furnace or coke oven gas resulting from the production of coke from coal, as well as petroleum coke and still gas produced at petroleum refineries. These are called byproducts because they result from the feedstock use of energy or the processing of nonenergy materials.
