In a process for the production of fiber substances from waste which contains aerobically unstable components, the waste is subjected to aerobic decomposition at a temperature of at least 50.degree.C in the presence of oxygen to form a fibrous mass and then the mass is treated with solvents which dissolve these components. This eliminates the odor characteristic of fiber substances produced from waste. An arrangement for carrying out the process is also disclosed.
