<p>Process and device for processing materials from which methane and other chemicals, being harmful to the environment, may escape, e.g. for processing manure or sewage sludge. The starting material is heated and the escaping gases are subjected to a washing treatment with water or a circulating solution of a chemical washed out of the gas, e.g. ammonia. The methane in the gas escaping from the washing device is burned and the developed heat is, at least partly, utilized for heating the starting material.</p> |
