Applications of various solid waste powders in functional coating materials

Journal Title: China Powder Science and Technology - Year 2025, Vol 31, Issue 1

Abstract

Significance In our daily life and industrial production, large amounts of solid waste are inevitably generated. The accumulation of this solid waste can significantly impact on the living environment and socio-economic development. To effectively address the severe challenges posed by this issue, this paper focuses on the innovative applications of solid waste in functional coating materials, exploring high value-added conversion pathways for solid waste and aiming to achieve resource reuse with high economic benefits. Progress This paper systematically reviews and explores strategies for resource reuse of various types of solid waste in functional coating materials, including mining tailings, industrial solid waste, and household plastic waste. The strategies take full advantage of the characteristics of solid waste, modifying it through physical and chemical methods, which greatly enhance the inherent properties of these materials. After modification, the solid waste can be applied to functional coating materials, enabling a range of specific functions such as flame retardancy, corrosion resistance, and self-cleaning. Considering the great potential and challenges in the resource reuse of solid waste, applying it to functional coatings is a promising and highly economical solution. This approach not only alleviates the environmental pressure caused by solid waste pollution but also achieves a high-value transformation of waste through technological innovation. Conclusions and Prospects Although much research has been conducted on the application of solid waste in functional coating materials, there is still a lack of large-scale commercial applications. Therefore, further cost reduction and process optimization are urgently needed to bring the experimental results to market. The resource reuse of solid waste is promising for future development. Applying solid waste to functional coating materials is an economical way to reuse resource. This approach not only significantly mitigates the environmental harm caused by solid waste but also successfully achieves its high-value resource reuse, paving an innovative path for environmental protection and resource utilization. To mitigate the environmental impact of mineral tailings, solid waste generated during metallurgy, municipal solid waste, and other types of solid waste, both enterprises and governments must work together. Under the premise of formulating relevant laws and regulations, enterprises must voluntarily fulfill their obligations to reduce solid waste emissions and enhance the recycling and resource utilization of solid waste, addressing the solid waste issue at its source.
