Composting represents one of the technologies of processing of biodegradable municipal waste. Samples collected from composting plants were analyzed chemically, physically and microbiologically. The pH of biowaste samples increased from 6.5 to 8.6. The total carbon to nitrogen ratio decreased in the course of composting from 40:1 up to the value of 25:1 while the total nitrogen to phosphorus ratio decreased from 10:1 up to 8:1. Indicator groups of microorganisms were monitored in compost samples. Representatives of the genus Enterobacter, namely E. cloacae and E. aerogenes, were identified in the samples on the basis of biochemical tests. The bacterial groups needed for efficient composting, i.e. the orders Bacillales and Actinomycetales, were present in appreciable amounts.
