Abstract

A solid fuel comprised of waste materials and a method of using the same are disclosed. The composition is made up of a heating value component, a neutralizing component and a nuisance waste component. Each of these components is a material which is readily available as a waste. Each component may be either solid or liquid, however, the total composition may not be more than 40% liquid. The nuisance waste component is a compound or mixture of compounds which often present disposal problems for industry. The nuisance wastes may include chlorinated hydrocarbons such as polychlorinated biphenyls, sulfur containing compounds, biological wastes and/or metals which are converted to stable and more easily disposed of compounds as the fuel briquette is burned in a kiln or furnace so that an inexpensive fuel is created from the waste products.
