It is crucial to integrate sustainability practices across the whole supply chain and the production process to make a manufacturing system sustainable. It is a demand in today's industrial sector, especially in developing nations like Bangladesh which has an emerging economy. A thorough literature analysis and expert input will identify the most important economic, environmental, and social assessment criteria for choosing sustainable suppliers. The Stepwise Weight Assessment Ratio Analysis (SWARA) method will determine the weights of the selected evaluation criteria. The ultimate ranking of suppliers in the Agro-food industry will then be determined using the Fuzzy Topsis approach utilizing the criterion weight from the SWARA method. This study is anticipated to help decision-makers in the Agro-food sectors of developing nations choose suppliers who are both long-term economically and ecologically sustainable
