Abstract
Composting is the most viable treatment for biodegradable solid waste. Numerous techniques have been developed by different agencies to carry out composting. The most common method is aerobic bin method carried out on small scale. Compost piles and windrow methods needs larger land area and are mainly carried out by industries. The total time for completion of composting depend upon the type of substrate and the methods employed. Moisture content, temperature, pH and C:N ratio are among the most important factors for carrying out composting. The present review emphasised on the estimation of time taken by different types of substrates under different methods of composting and the changes in temperature, pH and C:N ratio occurring therein.
