坤彩全力推進全球首套鹽酸萃取法二氧化鈦項目建設，這項獨創的鹽酸萃取法生產工藝在節能環保方面具備顯著優勢，長期來看，符合國家“碳達峰”“碳中和”的政策要求。工信部答復政協提案時表示，國家高度重視鈦白粉產業發展，積極推進新工藝產業化和資源綜合利用，未來或將二氧化鈦納入國家戰略資源儲備。在加快推進核心工藝攻關及新工藝試點方面，工信部將會同有關部門密切關注鹽酸萃取法鈦白粉工藝技術研發及產業化進展，穩步推進新工藝試點。

坤彩全資子公司正太新材料二氧化鈦項目總投資達數十億，于2019年下半年開工建設，原計劃于2021年初建成部分產能投產，該項目在建設時與東南電化簽訂了氯化氫供應合同，2020年萬華化學收購了東南電化相關項目并實施了技術改造和產業整合，公司被迫改變項目計劃重新建設相關配套設施來應對氯化氫供應不足的問題，對該項目投產造成延誤，年產20萬噸二氧化鈦及三氧化二鐵項目已于2022年4月份投入正式生產。

Kuncai, the world's first hydrochloric acid extraction process has significant advantages in terms of energy-saving and environmental protection, it is also in line with the national "carbon peak" and "carbon neutral" policy requirements. China's Ministry of Industry and Information Technology indicates that the state attaches great importance to the development of the titanium dioxide industry. The new process of industrialization and comprehensive utilization of resources will be actively promoted. In the future, titanium dioxide will be included in the national strategic resource reserve. The Ministry of Industry and Information Technology will pay attention closely to the progress of titanium dioxide process technology research and development and industrialization of hydrochloric acid extraction method with relevant departments, and steadily promote the new process pilot.

A wholly-owned subsidiary of Kuncai, Zhengtai New Materials Co., its titanium dioxide project, with a total investment of billions, has recently been put into operation with an annual production capacity of 200,000 tonnes of titanium dioxide and iron oxide.
