The results showed that in the present situation, considering that the cost of project) fixed and variable costs (are much higher than the proceeds of the residual income, this process is not from the private sector investors point of view. In order to examine the financial feasibility, three scenarios of change include a 15% reduction in fixed costs of the project, a 30% increase in revenue from the sale, and finally in terms of indirect benefits of reducing health costs due to proper waste management performance, Was investigated. The results showed that in terms of these changes in the above scenarios, the internal rate of return will be 40% and the benefit-to-cost ratio will be about 1.20 and the payback period will be 4.25 years, so the waste management process can be financially feasible. The results of this study can provide the necessary information for determining governmental incentives to make the process of waste management by the private sector.
