(WO9323351-A1)      A new composting plant consists of a number of separate reactors with a central aeration system. The aeration system is controlled and the process parameters of each reactor can be adjusted individually and independently. Pref. the temp., moisture content and compsn. of the air are controlled, and systems are provided for the sepn. of condensate and/or the recovery of waste heat. Filtration is provided for removing odorous components from the air, and a scrubber may be used for sepg. problematical substances.    USE/ADVANTAGE -   For composting biological waste materials. The ambient conditions in the reactors can be adjusted to suit the requirements of the microbiological conversion process during the composting period.
