Abstract
A method for producing hydrogen and/or other gases from steel plant wastes and waste heat is disclosed. The method comprises the steps of providing molten waste from steel plant like molten slag in a reactor. The molten slag is contacted with water and/or steam in the presence of a reducing agent to form a stream of hydrogen and/or other gases. The hydrogen and/or other gases can then be extracted from the stream of gases from the reactor.
