In biochemistry, cellulose acetate refers to any acetate ester of cellulose, usually cellulose diacetate. It was first prepared in 1865. A bioplastic, cellulose acetate is used as a film base in photography, as a component in some coatings, and as a frame material for eyeglasses; it is also used as a synthetic fiber in the manufacture of cigarette filters and playing cards. In photographic film, cellulose acetate film replaced nitrate film in the 1950s, being far less flammable and cheaper to produce.

A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900°C and 1,400 °C, are generally drawn off and recovered. There are also coking plants where the released components are burned: this is known as a heat recovery process. A layer of ash then forms on the surface of the resulting coke. The degassing of the coal gives the coke a highly sought-after porosity. The gases are broken down by fractional condensation into hydrocarbon tars, sulfuric acid, ammonia, naphthalene, benzol, and coke gas; these products are then purified in further chemical reactors. Germany still has five coking plants in operation to meet the needs of its domestic industry.
