Expeditious growth of population and urbanization has led the global challenge for Municipal Solid Waste
(MSW) management. An investigation on rapid composting of biodegradable city waste was carried out with
three treatments, two on a rapo-composter with and without consortia of thermophilic ligno-cellulolytic mi crobes and third is the common practice of compost producer. The quality of compost i.e. the maturity and
stability index was tested at four different stages of decomposition. After 30 days of decomposition it was
elucidated that rapo-composter with consortia (Bacillus sps., Streptomyces sps., Rhizomucor pusillus and Aspergillus
flavus) fasten the decomposition time. This paper finds uniqueness in deriving 10 maturity parameters, 6 stability
parameters with one parameter as confirmatory test of compost toxicity. It was concluded from the study that the
Water Soluble Carbon (WSC) and Organic Nitrogen (Org. N) ratio is the key regulator of maturity parameter and
the dehydrogenase (DHA) activity is important factor for compost stability.
