Wastes emerged as potential alternative energy to flourish in various useful materials and commodities for human demands. In the civilized nation's variety of industrial projects of plasma, reactors underwent the decision-making models, project approval and even exploitation stages from long ago. The current study comprised waste materials utilization in diamond deposition purposes via chemical vapor deposition for constructing future industries firstly. To select the best plasma reactor were employed seven multi-criteria decision-making models in combination with three kinds of weighing systems to select the best plasma reactor empirically. Initial data for assessment possessed from a deep literature review based on probative technologies. It was classified and prioritized the plasma reactors in a coherent connection for direct gasification operation and placed them in a relevant arrangement media for partial gasification assortment. The developed assortment of plasma reactors was generally indicated as alternating current, direct current, glow, microwave, high-Frequency plasma, laser, Plasmatron and flame at direct gasification operation respectively. The high degree of stability among multi-criteria decision-making models and the sensitivity analysis employed for the weights and ranks released for alternatives and criteria had confirmed the precision and validity required. Also, on the global level, the findings of the present study proved the implementation of direct current plasma gasification reactors in large scale industries.
