Abstract

The invention concerns a microbiological method for the decomposition of organic wastes, the waste material being subjected to a composting process under aerobic conditions in a closed container to which air is supplied. Air is passed through the waste material at intervals, the spent air being drawn off together with the gaseous decomposition products. The length of the intervals between the air feed periods is controlled as a function of the lowest value of the O2 concentration measured in the spent air. The spent air which collects in the space above the composting material is preferably drawn off at the same time as air is supplied, or shortly afterwards, the O2 concentration being measured at this time. Alternatively, the O2 concentration in the space between the heap of waste and the container end wall or the O2 concentration of the gas in the heap of waste can be monitored.
