Abstract
Abstract A method of and apparatus for converting a prepared refusesewage sludge mixture by biological decomposition into an earth substance, wherein the refuse-sewage sludge mixture is introduced into a container closed at all sides. Air is infed in a controlled manner transversely through the refuse-sewage sludge mixture within such closed container, and the decomposition process is carried out continuously.
