Immature and poorly stabilized compost may pose a number of problems related to their various applications and land disposal. Poorly stabilized compost may lead to production of various toxic compounds which may change soil chemistry and contaminate the ground water sources on land disposal. Present study focuses on Comparative study on assessment of compost maturity through carbon, nitrogen C/N ratio obtained in different phases of rotary drum composting and vermicomposting technique. Industrial sludge in the present study was collected from Common Effluent Treatment Plant (CETP) Bhiwadi in state of Rajasthan India. CETP Bhiwadi treating the waste water from large cluster of different small scale industries (SSI). The end product obtained in the study had lower C/N Ratio than initial value in both rotary drum composting and vermicomposting techniques and decrease in C/N ratios shows the organic matter breakdown, compost maturity and stabilization achieved.
