Manufacturing businesses in underdeveloped nations like Bangladesh began using Sustainable Supply Chain Management (SSCM) to assure and carry out their environmental duty. Obtaining sustainable output in the setting of SSCM is quite difficult. This study examines the knit composite industry's current Supply Chain Management (SCM) and its impact on the environment. The negative impact that existing SCM has on the environment is grave and hazardous. Three considerations environmental, social, and economic concerns are taken into account to close the gap between the SSCM & the firm's manufacturing process. These serve as examples of SSCM in the production process and aid in making it sustainable from the standpoints of the producer and the consumer. As a result, this article first expresses issues regarding the drivers in SSCM and how they are incorporated into the SSCM process. Then, several obstacles are identified & graded using the Analytical Hierarchy Process (AHP) & Triangular Fuzzy Numbers (TFN) technique. The decision-makers will be helped by this suggested model to reduce the main obstacles to SSCM.
