(DE19547784-A1)      Composting organic materials, especially refuse containing organic material, in an enclosed vessel (4) using forced aeration, comprises measuring the nitrogen content of the airstream leaving the composting vessel.    Also claimed are: (i) an arrangement for the above process where an enclosed vessel has a means for forced aeration, and instruments to measure the nitrogen content in the airstream leaving the vessel, especially to measure the electrical conductivity and/or ammonia content of the water entrained in the airstream; and (ii) a compost produced by the above process and/or arrangement.    USE -   Used compost organic materials such as waste (claimed) e.g. domestic waste containing organic matter, to produce fuel pellets or briquettes or to make part-composed products.    ADVANTAGE -   The process affords more precise control of the composting process so that a more satisfactory product is reliably obtained in less time, especially from domestic waste, than by known methods. The process minimises carbon dioxide generation by prematurely halting the composting process.
