“…Important factors in the process of composting are, particle size of the substrate, moisture content, temperature, pH, C:N ratio, nutrient content and toxic substances. Many studies have reported on the process of composting and quality of compost formed from different types of organic wastes (Goyal et al 2005;Caceres et al 2006;Huang et al 2017;Chaudhary and Mishra, 2019;Jain et al 2019). The present review was undertaken to evaluate the total time taken by different types of organic wastes to convert into compost and the changes in temperature, pH and C:N ratio during the process of composting.…”
