Abstract: Both the current cleaner production evaluation index system and the cleaner production standard in electrolytic manganese metal industry have played a significant role in cleaner production audit, performance assessment and promotion of the development and applications of cleaner production technologies. However, there still have several problems in the two systems, including lag in some index values, insufficiency of the indicators directly promoting the cleaner production, and narrow scope of the application of the systems. For future revision of the evaluation index system, the leading and proactive role of the LevelⅠreference values should be intensified, the indexes directly reflecting the cleaner production-related techniques, equipment and emissions be emphasized, and the application scope of the system be expanded. By establishing a practical and operable evaluation index system, the level of cleaner production of the entire industry should be promoted.
