Prior to commercializing a product of interest, techno-economic principles are used to determine viability of the process flow. The aim of this paper was to conduct a desktop research on the process flow of interest (the technology and the raw material of interest) using techno-economic approach thereby determining the commercializing a product. As much as Silicon Nitride based materials that are sintered through the application of Spark Plasma Sintering SPS technology have grasped the interest of researchers for commercial possibilities, a techno-economic study of commercializing Silicon Nitride based materials using SPS technology was not found during the desktop research. The results obtained indicated that there is a common agreement among authors about techno-economic application. It was therefore concluded that techno-economic approach/ principle(s) can be used to determine the commercialization of any product.
