Our main services and products include (1) wastewater treatment, (2) river water quality management, and (3) microbial products that are used for water quality enhancement and pollutant removal. For the fiscal year ended October 31, 2023, our revenue primarily comes from (1) provision of wastewater treatment service, representing approximately 25.49% of our revenue; (2) provision of river water quality management service, representing approximately 46.39% of our revenue; and (3) sale of microbial product, representing approximately 28.03% of our revenue.

We have an in-house research and development (“R&D”) team with members possessing technical expertise in engineering and chemistry as well as a sharp business sense that we believe can accurately capture and meet our customers’ needs. As of the date of this prospectus, we own 12 patents and 9 software copyrights.

We have received a number of industry awards and certifications recognizing our success and achievements, including the “Yantai City Industrial Design Center” awarded by the Yantai Municipal Bureau of Industry and Information Technology in 2022, the “Yantai New Special Expertise Enterprise” awarded by the Yantai Municipal Bureau of Industry and Information Technology in 2022, the “High-Tech Enterprise” awarded by the Shandong Provincial Department of Science and Technology, Shandong Provincial Department of Finance, and Shandong Provincial Taxation Bureau of the State Administration of Taxation in 2019 and 2022, the “Shandong Province ‘One Enterprise, One Technology’ Innovative Enterprises” awarded by the Shandong Provincial Bureau of Small and Medium Enterprises in 2015.

Our Products and Services

Our main services and products include (1) wastewater treatment, (2) river water quality management, and (3) microbial products that are used for water quality enhancement and pollutant removal. For the fiscal year ended October 31, 2023, our revenue primarily comes from (1) provision of wastewater treatment service, representing approximately 25.49% of our revenue; (2) provision of river water quality management service, representing approximately 46.39% of our revenue; and (3) sale of microbial products, representing approximately 28.03% of our revenue.

Set forth below are the services and products provided by our Operating Subsidiary:

Wastewater Treatment

Our wastewater treatment services primarily focus on protein-rich wastewater treatment. Our innovative protein-rich wastewater treatment system is designed to address the environmental challenges associated with high-concentration organic waste faced by the agri-food processing industry. This system efficiently extracts and repurposes valuable proteins and polysaccharides from soybean wastewater, a common byproduct of soybean product production. Our process consists of three key steps: (1) extraction through centrifugal separation and temperature regulation, (2) purification and concentration using ultrafiltration, nanofiltration, and reverse osmosis, (3) followed by sterilization and spray drying to produce edible protein products. Unlike traditional multi-stage biochemical treatments that merely aim to meet discharge standards, our method recovers a substantial amount of soluble proteins and polysaccharides, significantly reducing raw material and water costs for our customers, while ensuring the reusability of our treated water.

River Water Quality Management

Proper ecological river restoration and treatment play a vital role in constructing contemporary eco-cities and promoting sustainable urban development. Contrary to the traditional river restoration methods which consist of physical method (e.g., cleaning the river bottom silt and transfer artificial oxygenation into the river, which temporarily alleviate the pollution but do not address the root cause) and chemical method (referring to the addition of algaecide and flocculant into the river as cleaning agents, which tends to create secondary pollution and cause further damage to the underwater biological environment), we adopt a microbial bacteria remediation technology that uses microbial bacteria to promote the growth of pollutant-decreasing microorganisms, resulting in an increase in the dissolved oxygen concentration in the river and transforming the environment from anaerobic to aerobic. We believe the microbial bacteria remediation technology will increase biodiversity in the long run, raise the level of dissolved oxygen significantly, and eliminate black odor water in rivers.

Microbial Products for Water Quality Enhancement and Pollutant Removal Purposes

We have independently developed a variety of microbial products and agents that can quickly and efficiently improve water quality, remove pollutants, and treat black odor water. Our main products include a chemical oxygen demand (COD) reducing bacteria where COD refers to the amount of oxygen needed to oxidize soluble and particulate organic matter in water); an efficient algae removal bacteria, which can quickly remove algae, improve water transparency, dissipate sedimentary substrate and organic residues from the bottom of waterbodies, and prevent water eutrophication; an ammonia nitrogen decreasing bacteria, which is mainly used to decrease ammonia nitrogen in wastewater by cultivating biological strains that consume pollutants and removing organic ammonia nitrogen and inorganic ammonia nitrogen in water; a river conditioner, which is widely used in the ecological treatment and restoration of lakes and rivers; and a protein-rich wastewater treatment.
