Secretary of the Board, can you provide information on the following: 1. Does the Company have rare earth separation technology and plans to enter the rare earth industry? 2. Does the Company have sodium ion separation technology and plans to enter the sodium ion battery industry? 3. The GTR3 and GTR4 high and middle-pressure membrane modules developed by the Company differ from traditional double membrane treatment. Are the metal ions (such as lithium, sodium, magnesium, and rare earth metals, etc.) separated by this device more thoroughly than traditional methods? Thank you!

Others

Dear investor: Hello! 1. Moving forward, the Company will monitor market dynamics and continuously focus on market development opportunities according to market demand. 2. The independently developed GTR series medium-pressure membrane device (GTR3) and high-pressure membrane device (GTR4) are mainly used for removing soluble ions in water, with a removal rate of up to 98% and a water reuse rate of over 90%.

Secretary of the Board, hello! The National Development and Reform Commission recently issued the 14th Five-Year Plan for the Development of Urban Sewage Treatment and Resource Utilization, aiming to improve water ecological environment quality, accelerate the formation of a rational layout, systematic coordination, safe and efficient, energy-saving, low-carbon pattern for urban sewage collection, treatment, and resource utilization. The water reuse rate of national prefecture-level and above water-deficient cities reaches over 25%, while in the Beijing-Tianjin-Hebei region it exceeds 35%, and in the middle and lower reaches of the Yellow River basin, the goal is to reach 30%; the harmless disposal rate of urban sludge is targeted to exceed 90%. Will there be any impact? Thank you.

Others

Dear investor: Hello! As a leader in the sewage resource recycling industry, the Company is well-positioned to capitalize on the accelerated national sewage resource recycling reform and the ongoing implementation of national sewage treatment policies, which will bring new opportunities for the Company's industrial development.

Secretary of the Board, hello. General Manager Mr. Zhang Jianfei has been engaged in liquid separation research for over 30 years. If the Secretary is uncertain about this issue, please inform Mr. Zhang for consultation before replying. The Company holds an invention patent for a method of treating high-salinity water using a multi-stage electrically driven ion membrane process, which can separate monovalent cations and multivalent cations with high recovery rates and low cost. As we know, lithium is a monovalent cation, and magnesium is a divalent cation. Given the high magnesium-lithium ratio in China's salt lakes, can this patent, or an improved version of it, be used to separate lithium salts from high magnesium-lithium ratio brine water?

Others

The Company's zero-discharge salt separation technology for high-salinity water is composed of unit operations in physics, chemistry, membrane separation, and evaporation, etc. These unit operations can be customized and combined to be used in lithium extraction projects. Currently, the Company does not have any existing orders for salt lake lithium extraction. Investors are advised to make rational investment decisions and be aware of investment risks.

The Company's prospectus disclosed that in March 2018, it had cooperated with Lianli New Materials on a wastewater lithium extraction project but did not achieve effective results. Lianli New Materials applied for relevant patents in December of the same year, with patent number CN109650416A (currently under substantive examination), many of which used the Company's technology to achieve a lithium recovery rate of ≥ 90%. Lianli New Materials applied for cancellation last month and transferred the patent to Kaiman Aluminum. I wonder if the Company has noted this? Is the Company planning to file a counterclaim regarding this patent? It is hoped that the Company will strengthen its awareness of protecting intellectual property rights in the future, and utilize its own technical advantages to enhance research and promotion of lithium extraction technologies!

Others

Dear investor: Hello! Based on the cooperation agreement, the Company jointly owns the results of the pilot test with Lianli New Materials. The Company will further verify and take corresponding measures regarding this matter. Thank you for your suggestion and attention.
