The current cluster study followed the objective of a similar research about evaluating the initial data of 57 various kinds of IFMPI in terms of energy, materials streams, and technical aspects.<br> <strong>Methods:</strong> The present research took into consideration the assessment of initial data in the screening step of project identification to further processing via Multi-Criteria Decision Making (MCDM) models and developing a techno-economic assessment model empirically.<br> <strong>Results:</strong> A good reliability (&nbsp;a = 0.808) among the weight values in MCDM models confirmed a developed classification. The proposed economic assessment model is able to estimate the outlays for the screening step of IFMPI projects.<br> <strong>Conclusion:</strong> It can be concluded that the present study executed IFMPI in input and output materials besides &nbsp;energy streams and placed them in the reliable ranking levels using MCDM models along with Data Envelopment Analysis (DEA).</span></span><br> &nbsp; MCDM models, Food manufacturing, Food processing practices, Industries, 41 53 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-435-1&slc_lang=en&sid=1 Malek Hassanpour malek.hassanpour@yahoo.com 100319475328460011148 100319475328460011148 Yes Department of Environmental Science, UCS, Osmania University, Telangana State, Hyderabad, India.
