Circular Economy Integration in Nanotechnology: A Socio-Economic Evaluation of Zinc Oxide Nanoparticles in Sustainable Alloy Production

Abstract

The integration of nanotechnology into industrial production has opened new pathways for sustainable development, particularly within the framework of the circular economy. This study examines the role of zinc oxide (ZnO) nanoparticles in enhancing sustainable alloy production from a socio-economic perspective. The primary objective is to explore how the use of ZnO nanoparticles contributes to resource efficiency, waste reduction, and improved material performance, while also assessing economic feasibility and industry adoption. A quantitative research design was employed using a structured questionnaire distributed among professionals in manufacturing, construction, and materials-related industries. The study focuses on key factors including environmental awareness, perceived economic benefits, and perceived barriers influencing technology adoption. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine relationships among variables. The findings reveal that perceived economic benefits have the strongest positive effect on technology adoption, followed by environmental awareness, while perceived barriers negatively influence adoption decisions. The model demonstrates moderate to strong explanatory power, indicating that socio-economic factors significantly shape the adoption of nanotechnology in industrial processes. The results further suggest that ZnO nanoparticles are perceived to enhance alloy durability and reduce environmental impact, supporting circular economy objectives. The study concludes that integrating ZnO nanoparticles in alloy production offers both economic and environmental advantages. However, barriers such as high costs and limited technical knowledge must be addressed. It recommends policy support, industry training, and awareness initiatives to promote sustainable nanotechnology adoption. This research contributes to interdisciplinary literature by linking materials science innovation with socio-economic and sustainability perspectives.
