Sustainable Manufacturing as an Approach for Achieving Operational Performance Excellence (Case study)

Sustainable Manufacturing (SM) is an increasingly adopted approach, especially in the industrial sector, that promotes non-wastefulness by reducing negative impacts, enhancing energy and resource efficiency, and minimizing waste. In this study, a proposed theoretical framework for the logical relationship between the research variables is represented. The research study is a Case Study based on the descriptive analytical method for one of the pharmaceutical companies operating in Egypt to examine the impact of implementing Sustainable Manufacturing on Operational Performance Excellence (OPE). The sample of analysis is a Purposive Sample of the production line of product (X) suspension, where a comprehensive survey was conducted across all employees working on the production line of product (X), as its manufacturing includes the common steps shared by majority of liquid preparation line products, and the increase in the number of unnecessary activities on this production line compared to other pharmaceutical products. A dual-software approach, combining the strengths of Smart PLS V.3 for Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis with IBM SPSS V.29 for descriptive and inferential statistics is used to test all the hypothesized relationships under investigation. The results and empirical evidence shows the significant negative effects of unnecessary activities on operational performance underscore the importance of identifying and eliminating wasteful processes and activities within manufacturing operations, although respondents generally perceive minimal presence of unnecessary activities and wastes in their production processes. The findings also identify that SM implementation and unnecessary activities elimination represent critical success factors for OPE. As SM implementation serves as a critical driver of OPE, unnecessary activities represent significant impediments to performance outcomes.
