Abstract:

As a high-energy-consuming and high-carbon-emitting industry, the ceramic industry is facing significant pressure to reduce emissions under China’s “dual carbon” goals.Low-carbon technologies are crucial for its transformation.This study systematically analyzed the current development status of low-carbon technologies in the ceramic industry, both demestically and globally, compiling a list of such technologies categorized into raw material substitution, ultra-high energy efficiency improvement, energy structure adjustment, and product structure adjustment. To scientifically evaluate these technologies, a comprehensive evaluation system was established, comprising 12 indicators across six dimensions: energy consumption, technical efficiency, economic benefits, pollution control, carbon reduction effectiveness, and policy orientation. The entropy weight-TOPSIS model was adopted for comprehensive analysis. The entropy weight method was used to determine the weights of each indicator. The results show that energy saving and carbon emission reduction are the core concerns, with the technology penetration rate and technology energy saving rate being the most critical decision-making indicators. The weights of energy consumption and carbon emission reduction are also significant. The entropy weight-TOPSIS method is applied to evaluate 10 low-carbon technologies already implemented in the ceramic industry. The results indicat that ceramic thinning technology (0.76), raw material dry preparation technology (0.58), coal-to-gas conversion technology (0.49), and waste heat utilization technology (0.43) have high relative closeness scores, making them the currently recommended priority options. Ammonia-hydrogen zero-carbon combustion technology had the lowest relative closeness. Technologies such as continuous raw material slurry preparation systems, integrated powder preparation processes, and photovoltaic power generation are at a medium level.Through multidimensional evaluation, this study reveals the priority sequence of low-carbon technologies in the ceramic industry, providing a decision-making reference for technology selection in the industry’s green and low-carbon transition.

Key words: ceramic industry, low-carbon technology, indicator system, entropy weight-TOPSIS evaluation, carbon emission reduction
