Composting is a preferable treatment option for putrescible waste disposal. In the small-scale composting, the control of the process is easy and high quality compost is usually produced while the conditions of industrial composting and small-scale composting are so different especially in developing country that municipal solid waste (MSW) is collected as commingled. Unfortunately, there is still a lack of information and experiences regarding the successful industrial composting from commingled municipal solid waste (CMSW). Therefore, this study was conducted on the compost production from CMSW in Shiraz City, Iran, with the composting capacity of 100 tonnes per day. The common process of windrow composting was modified for industrial composting in Shiraz City. The efficiency of the modified process was assessed using physical, chemical, and economic analyses. In addition, the maturity and stability of produced compost was evaluated using different indices such as fertilizing index (FI), clean index (CI), static respiration index (SRI), cumulative respiration index (CRI), and C-CO2 production index (C-CO2 Index). Finally, solutions and suggestions were presented to improve the system performance. Results showed that although the input putrescible waste to composting site has low homogeneity, produced compost in Shiraz City has a “good” quality. The produced compost with FI and CI of about 4.2 and 3.6, respectively, has high fertilizing potential and medium heavy metal content and can be sold without any restriction. Based on the economic analysis, poor marketing, strategies of bad marketing, lack of public awareness, and visible impurities, in spite of complying with the required standards, are the main reasons for the low sale price. The results of this study can be valuable for industrial composting in the cities where wastes are not separated at source.
