On April 14, Tianyuan Co., Ltd. announced its intention to invest 930 million yuan in building a project that aims to produce 200,000 tons per year of ion-exchange membrane caustic soda through the comprehensive utilization of waste salt. Tianyuan Co., Ltd. stated that it has invested in a project to produce 100,000 tons of titanium dioxide via the chlorination process per year. In order to properly handle the waste salts generated during the production of titanium dioxide by this method and ensure a stable supply of chlorine, the company is working to expand its basic chlor-alkali chemical industry chain. It aims to establish an integrated green circular industrial system featuring complete supply of key resources and efficient utilization of those resources, covering the areas of chlorine, titanium, phosphorus, iron, and lithium. Its subsidiary, Yibin Haifeng Huirui Co., Ltd., has acquired new land and is investing in the phased construction of a project that will produce 200,000 tons per year of ion-exchange membrane caustic soda through the comprehensive utilization of waste salts.
This project appears to be a significant move by Amagasaki Co., Ltd. in the areas of circular economy and the extension of industrial chains; in particular, the recycling of waste salt represents a noteworthy aspect of it. There are several points worth noting: In terms of technical feasibility, the treatment of waste salts generated in the production of titanium dioxide via chlorination has always been a challenge for the industry. If industrial-scale utilization of these waste salts to produce caustic soda can be achieved, it would hold great value as a reference for other companies in this sector. However, the specific process route and impurity control strategies have not been disclosed yet, and this is the key aspect. Economic analysis: An investment of 930 million yuan enables a production capacity of 200,000 tons; the unit investment cost is lower than the average level for new projects in this industry (which is generally around 5,000 yuan per ton), likely due to the utilization of existing infrastructure. It is recommended to pay attention to the energy consumption and cost data in the environmental impact assessment report going forward. It should be noted that the actual performance of such projects involving comprehensive utilization of resources often depends on the stability of the raw materials; it is recommended to continuously monitor the reliability of the sources of these waste salts.
