(WO9415893-A1)      For the microbial degrading of organic waste, with an intermediate air flow through it, the duration of the rest periods between ventilation is controlled according to the lowest value of the O2 content of the exhaust air.    Also claimed is an assembly with a container (1) and a ventilation base (3) formed by adjacent longitudinal profiled members or rods (23) at a small gap from each other.    The exhaust air is extracted from the zone over the waste material at the same time as the air is fed in, or shortly after. The ventilation periods have a duration of 1-5 minutes, with a ventilation air vol. according to the capacity of the container. The waste material temp. is held below 75 deg.C. The ventilation air is fed in upwards, from below. The extracted air is fed through an active filter. The ventilation period duration is controlled so that the O2 content of the exhaust air does not fall below 16 Vol.%.    USE/ADVANTAGE -   The operation is for rotting and microbial degrading of organic waste material. Method gives an effective control of the rotting process, where ventilation air is fed through intermittently.
