Coal is an important energy source but also a major source of pollution in China. To address this, clean coal technology focuses on using coal in ways that don't produce pollution from burning it. The authors suggest that finding effective, eco-friendly ways to use coal without burning it is essential for the future. By exploring alternatives to burning coal directly for energy, like non-fuel uses, we can reduce the environmental impact. They highlight the importance of non-fuel applications for coal in clean coal technology and propose various methods to achieve this goal.
