Abstract: In this article, a clear-cut comparative research has been conducted on various types of energy production technologies utilised for bagasse including combustion, pyrolysis, gasification, anaerobic digestion and alcoholic fermentation. Furthermore, these technologies have been analysed and modelled in MATLAB software to select its best usage in the conditions of Iran. Moreover, it takes into consideration three technical, economic and environmental viewpoints along with the development of an essential and acceptable data bank. In the technical study, parameters which are of great significance in implementation and manufacturing the technologies are determined. Then with the help of creditable methods of evaluation such as Delphi and focus group, these parameters are compared and weighted. In the economic study, with the calculation of economic indicators such as break-even point, net present value, internal rate of return and payback period, these technologies were compared. In order to facilitate decision making, three scenarios were considered based on international foreign currency. The environmental comparison of technologies were also made by calculating the degree of greenhouse gases reduction and other polluting gases with regard to the determined emission factors for the power plants in the country and their related external costs.
