Investigate the barriers of implement green supply chain in Mazandaran steel industry with a combined approach BSC / BWM

The concept of green supply chain management formed in manufacturing industries and recently put its focus on environmental issues. Various industries are trying to identify barriers for green supply chain implementation. In the past decade, due to the continuous environmental damage such as increased pollution, exhaustion of natural resources, extinction of animal and its harmful effects on humans, the growing importance of green supply chain management exists. A great tendency can be seen in Various industries to implement green supply chain. There are many obstacles to the successful implementation of the green supply chain that The aim of this research is identifying barriers to implementation of this concept by concentrating on the green supply chain researches. In this study, the combination of the BSC / BWM used and for the first time, the barriers to green supply chain were measured in terms of the Balanced Scorecard. This obstacle identified by customization model through a number of steel industry experts ranked by utilizing the best-worst method as a novel multi-criteria decision-making method. The results showed that internal processes and lack of clear environmental objectives, Lack of customer awareness about GSCM and green products and lack of technology, materials, and processes are the most important dimensions and criteria for green supply chain in the Mazandaran province steel industry respectively. Finally, some suggestions were given to overcome these barriers and reduce their effects.
