(WO9811035-A1)      In a process to treat effluent air containing organic particles discharged from a thermal treatment process, the effluent air is returned to the thermal treatment esp. a force-ventilated composting chamber, enriched as necessary with oxygen, for renewed treatment. The novelty is that: (a) the effluent air gases are re-heated before being returned to the treatment chamber; (b) the gaseous metabolic products are separated from the ambient air by preferably a molecular sieve; (c) the mixture of rotting particles is treated alternately with aerobic and anaerobic gas mixtures, depending on the nitrogen content; (d) depending upon the dominant strain of micro-organisms present, the rotting mixture is treated alternately with a moisture-saturated and a hygroscopic mixture of gases; (e) water is added to the effluent gases before they are returned to the gas treatment chamber.    USE -   The process promotes the biological-thermal composting process, or stabilises the organic components within a composting waste mass. The less cells are generated by a composting mass in an atmosphere with a low oxygen content.    ADVANTAGE -   The volume of cells generated is minimised; these do not have to be subsequently broken down to form a mature compost mass or one capable of storage.
