Chain Expo | Serbia's Silver Bell Group visits Guogangtong and shows strong interest in solid-liquid separation technology and aquaculture wastewater purification and extraction technology

2025-08-22

On July 17, 2025, the highly anticipated Chain Expo was crowded with people, attracting numerous international companies from all over the world to actively participate. The delegation of Silver Bell Group, a well-known Serbian enterprise, paid special attention to the independent research and development of solid-liquid separation technology and aquaculture wastewater purification and extraction technology by Guogangtong. They made an important visit to Guogangtong and conducted in-depth exchanges on the technology, showing strong interest.

On the morning of that day, the Silver Bell Group delegation arrived at the exhibition area of Guogangtong located at the Chain Expo. As a leading enterprise in the field of Agricultural Waste resource utilization, Guogangtong showcased multiple cutting-edge technologies and innovative solutions at this Chain Expo. Among them, solid-liquid separation technology and aquaculture wastewater purification and extraction technology attracted the attention of many participants, and Silver Bell Group was one of them.
During the visit, the technical team of Guogangtong provided detailed technical explanations to representatives of Silver Bell Group. The solid-liquid separation technology and the purification and extraction technology of breeding liquid waste are innovative technologies independently developed by Guogangtong for the treatment of cow breeding manure, achieving targeted output of "nutrient base nutrient solution regenerated water", effectively solving industry pain points such as difficult treatment of cow breeding manure, low recovery rate, and limited utilization added value.

The advantages of this technology are very significant. The nutrient base is rich in a large amount of organic nutrients, etc. After blending, it can be directly used as a feeding material for animal protein insects. The high value-added animal insect protein obtained after breeding meets the needs of the breeding industry chain; The separated regenerated nutrient solution is rich in a large amount of nitrogen, phosphorus, and potassium inorganic salts, which are important basic raw materials needed for algae, soilless cultivation, and biological fermentation mother liquor; Reclaimed water can be used as reclaimed water, aquaculture water, high-density fish farming supplementary water, and even higher purity according to needs, and applied to various links in the supply chain.
Relying on this resource utilization technology system that covers the entire process of "collection, treatment, transformation, and application" of dairy cow manure, Guogangtong focuses on biotechnology and constructs a sustainable industrial ecology around the recycling of Organic Waste and the utilization of agricultural and animal husbandry resources. Integrate resources such as technology research and development, equipment manufacturing, and project operation to provide one-stop services for large, medium, and small-scale breeding farms, and provide solutions for industrial green transformation and upgrading. The representatives of Silver Bell Group listened attentively, occasionally raising questions about technical details, application cases, and future cooperation possibilities, and the two sides engaged in lively discussions.

The relevant person in charge of Silver Bell Group stated that they have been seeking advanced technology partners globally to enhance their competitiveness in the fields of agricultural breeding and environmental protection. The solid-liquid separation technology and the purification and extraction technology of aquaculture wastewater are highly compatible with their business development direction, and are expected to bring new opportunities for their company's business expansion and innovation. This visit and exchange have given them a deeper understanding of the technology. In the future, a professional team will be arranged to further connect with the China Hong Kong Stock Connect and explore the specific mode and feasibility of cooperation.
The China Hong Kong Stock Connect also welcomes the visit of Silver Bell Group and looks forward to establishing a long-term cooperative relationship with this Serbian enterprise. Through this exchange, both parties have enhanced mutual understanding and trust, laying a solid foundation for future cooperation in technology and market expansion. With the continuous integration and development of the global industrial chain, cross-border technology exchange and cooperation like this will bring more development opportunities for enterprises, and also promote technological progress and innovative development in the agricultural breeding and environmental protection industries.
