From August 14th to August 19th, Professor Su Xintai, supported by the China-Belarus International Cooperation Exchange Program of the National Natural Science Foundation of China (Regulation Synthesis and Performance Study of Heterogeneous Fenton Catalyst based on Mesoporous Fe-N-C Material, 22111530287), and Mr. Tian Guoji, the General Manager of Guangzhou Kaicheng Drying Equipment Co., Ltd., visited and exchanged with the Institute of General and Inorganic Chemistry of the National Academy of Sciences of Belarus.

Professor Alexander RATKO, Deputy Director of Scientific and Innovation at the Institute of General and Inorganic Chemistry of the National Academy of Sciences of Belarus, Dr. Tatyana Kouznetsova, and others received the Chinese delegation and accompanied them to visit the largest sewage treatment plant in Belarus, the Minsk Sewage Plant.

During the visit, both sides exchanged and reported on the progress of the project, and conducted in-depth discussions on future cooperation prospects. China and Belarus will carry out close cooperation in the publication of papers, engineering and technical development, and industrial applications. They also signed a five-year cooperation agreement and will carry out cooperative research in the following three areas:

1. Production of adsorbent materials from urban sludge, production of humic acid potassium fertilizers, and application development;

2. Key technology development and application of peat catalytic production of humic acid potassium/humic acid potassium fertilizers;

3. Key technology development and application of resource utilization of potassium mine tailings for mineral fertilizer production.

Professor Su Xintai is giving a progress report on the project at the research institute

Project Background

Belarus has potassium salt reserves of 7.3 billion tons, and the mineable amount of potassium salt in 2021 is 600 million tons, accounting for 18% of the global total. The potassium fertilizer production exceeds 12.7 million tons. The Starobin mine is the largest in Belarus and the third largest in the world, with reserves of 10 billion tons. China imports approximately 2 million tons of potassium fertilizer from Belarus each year, making it one of China's major potassium fertilizer suppliers. Potassium fertilizer resources are a priority area for cooperation between China and Belarus and have significant strategic importance. The overall cooperation environment is good, and there is tremendous potential.

The total assessed reserves of peat in Belarus are 2.4 billion tons, with approximately 12% suitable for industrial development, covering an area of approximately 89,000 hectares, with reserves of approximately 26.9 million tons. The current annual mining volume is 2 million tons. Most of Belarus' peat is used for fuel and low-end improvement fertilizers. The development technology and quality are relatively backward, while China's demand for peat in the soil improvement and breeding industry is increasing. The China-Europe peat train was opened for the first time in 2022, exporting 12,000 tons of peat to China, and will export hundreds of thousands of tons annually in the future. Therefore, there is immense cooperation potential between China and Belarus in the development and utilization of peat resources.

The cooperation partner from Belarus is Professor Andrei Ivanets from the institute, who was elected a Corresponding Member of the National Academy of Sciences of Belarus in 2021. The two sides have already collaborated and published 7 academic papers in professional journals such as Science of the Total Environment, Chemosphere, and Journal of Environmental Chemical Engineering. The Belarusian side has a good research foundation and achievements in inorganic adsorbents, catalytic materials, and potassium fertilizer production and processing technology. Professor Su Xintai's team from the Chinese side has a good research foundation in peat, urban sludge, catalytic production of potassium humate fertilizer from biomass solid waste, and the utilization of potassium mine tailings. Guangzhou Kaicheng Drying Equipment Co., Ltd. from the Chinese side has excellent engineering practice and experience in pyrolysis and drying equipment and processes. The three parties will strengthen cooperation in solid waste treatment and resource utilization in the next five years to promote China-Belarus cooperation and explore the markets of the European Union and the Eurasian Union.
