Founded in 2000, SEAWIN is an enterprise focused on the harvesting and utilization of marine biological resources for the advancement of agricultural opportunity. Thanks to the technological advantages of Ocean University in China and the rich local marine resources, we have developed and introduced a new type of seaweed fertilizer. Currently, our main line of products include seaweed extract, seaweed fertilizer, seaweed foliar fertilizer, common formula fertilizer, and fertilizer raw materials.
Our seaweed fertilizer plays an outstanding role on the improvement of the ecological environment in topsoil. This results in better food quality by adding nutrients for plants to grow stronger. SEAWIN places great emphasis on the quality management of our products and we have been granted a series of international certifications, like the ISO9001 Quality Management System Certification, ISO 14001 Environmental Management Systems Certification, ISO 18001 occupational health and safety management system certification and ECOCERT Certification.
By providing superior products and services to farmers, houseplant enthusiasts, and agricultural organizations all over the world, we have developed and grown branches in the USA and Australia, and our products are exported to more than 50 countries.
With 18 years of technical resources accumulation, more than 100 researchers are engaged in the research and development department of SEAWIN. We have been collaborating with universities and related research institutions for many years. Thanks to these research efforts, we have obtained nearly one hundred patents (including 32 patents related to seaweed fertilizer) and dozens of other major innovations.
Over the last three years, SEAWIN has engaged in 39 research projects regarding technological innovation, such as 5 projects in Ministry of Science and Technology (China), 2 provincial projects, 2 projects in National Marine Fisheries Service, and we have made fruitful achievements through these projects.
SEAWIN has built 3 seaweed product production bases in Jiaozhou Qingdao, Rushan Weihai and Rongcheng Weihai, covering a total area of 400 thousand square meters.
In this production base, we have a non-destructive green algae testing workshop, resource utilization of green algae workshop, biological organic fertilizer processing workshop, and organic water soluble fertilizer workshop. Highly automatic processing equipment is utilizes, like our dewatering extruder, bailing press, reaction tank, and microbial fermentation systems. These machines minimize manufacturing costs as well as improve output and efficiency. From this facility, SEAWIN can produce 10 thousand tons of green algae powder, 2 thousand tons of green algae polysaccharides, 300 thousand tons of biological organic fertilizer and 100 thousand tons of organic soluble fertilizer annually.
The Rushan production base is located close to the Yellow Sea with abundant marine biological resources, such as oyster, kelp and byproducts of aquatic products. Here we have a protein polypeptide workshop and biological organic fertilizer workshop. The base is outfitted with production equipment like a triple-effect concentrator, reaction tank, degradation tank and spray drying tower. The annual output of marine protein polypeptide and biological organic fertilizer is 2 thousand tons and 200 thousand tons respectively.
Both the Rongcheng production base and Rushan production base are located in Weihai. Relying on the location advantage, there are rich kelp resources near the Rongcheng production base which is equipped with highly automatic washing equipment, a blanching device, conveyor, and fully automatic food grade packing machine. The output of food grade kelp is 50 thousand tons annually in this production base.
