Located in the vibrant and fertile land of Yishui, Shandong Province, Shandong Kunda Biotechnology Company Ltd., since its establishment in 2009, has been committed to deep cultivation in biochemical engineering and practicing green development. Through precise industrial layout, continuous technological breakthroughs, and unwavering commitment to responsibility, it has gradually grown into a leading enterprise in the industry with both scale and core competitiveness. Rooted in the Yishui Economic Development Zone, and relying on regional resources and innovative technologies, SHANDONG KUNDA has steadily advanced in the fields of food additives, fine chemicals, and pharmaceutical intermediates, writing a remarkable chapter of independent development and industrial empowerment.
SHANDONG KUNDA leverages local resource endowments to build a characteristic industrial system centered on sweet potatoes, achieving a full-chain upgrade from basic raw materials to high-value-added products. Utilizing the abundant sweet potato resources of Yishui, Linyi, and imported cassava resources from Southeast Asia, the company has built an integrated upstream and downstream production line with fermentation technology at its core, transforming ordinary sweet potatoes into diverse fine chemical products. This has extended into seven high-value-added industrial chains, including potassium sorbate, vitamin B3, and 2,3-dichloropyridine, producing more than 100 products widely used in food, pharmaceuticals, cosmetics, and other fields. KUNDA BIOTECHNOLOGY COMPANY focuses on the in-depth development of its core products. Its sorbic acid (potassium) products hold a 40% share of the global market, and its ethylamine series products have the largest market share in China. Nicotinamide has been awarded the title of "Single Champion Product in Shandong Province's Manufacturing Industry." With its superior quality, its products are exported to more than 120 countries and regions worldwide. The products have passed multiple international certifications, including ISO 9001, ISO 22000, KOSHER, and HALAL, solidifying its foundation in overseas markets.
Technological innovation is the core secret to SHANDONG KUNDA BIOTECHNOLOGY's continued leadership. The company is deeply committed to the research and development of fermentation processes and biocatalysis technologies. It has been successively recognized as a national high-tech enterprise, a provincial-level manufacturing single-champion enterprise, and a provincial-level enterprise technology center. It has established a mechanism for industry-university-research collaboration with multiple universities and research institutions, including Jiangnan University and Shandong University, jointly building a biocatalysis joint laboratory and overcoming several core technologies in the industry. Among its achievements, the company's jointly developed biological method for niacin production has elevated niacin conversion concentration to the highest international level, achieving green refining with zero emissions. This technology won the second prize of the Shandong Provincial Science and Technology Progress Award. Based on this technology, the world's first 10,000-ton-level biological niacin production line was built. In 2024, the product's output value reached 834 million yuan, with exports accounting for nearly 60%. At the same time, the company, guided by green development principles, invested in a fusel oil comprehensive utilization project. Using advanced processes to transform waste into valuable resources, it solves the industry's waste disposal problems while separating high-value-added products, building a circular economy model of "resources-products-recycled resources," and creating a unique bio-chemical industrial park.
Thanks to its sound business strategy and continuous capacity upgrades, SHANDONG KUNDA has achieved simultaneous growth in scale and efficiency. The company produces 60,000 tons of ethylamine, 120,000 tons of acetaldehyde, and 60,000 tons of refined sweet potato starch annually. Its ethylamine production accounts for 70% of the national total, filling a gap in the provincial industry. In 2024, the company achieved an output value of 2.77 billion yuan, tax revenue of 106 million yuan, and export value of 144 million US dollars. From January to September 2025, the output value reached 2.19 billion yuan, maintaining a steady growth trend. Currently, the company is advancing a 660 million yuan acetaldehyde industry chain extension project, which will be constructed in two phases, including 30,000 tons/year of 3-cyanopyridine, 30,000 tons/year of nicotinamide, and 20,000 tons/year of 2,2-bipyridine production lines. 429 sets of new equipment will be purchased. Upon completion, the project will further strengthen the industry chain advantages and enhance the global competitiveness of its core products.
For many years, KUNDA BIOTECHNOLOGY COMPANY has repeatedly received industry recognition for its outstanding comprehensive strength, being selected among the top 200 Chinese light industry enterprises, the top 500 Chinese agricultural enterprises, and the top ten enterprises in the Chinese food additives and ingredients industry. As a key provincial-level agricultural industrialization leading enterprise, it deeply empowers local development. The company purchases nearly 200,000 tons of sweet potatoes from Yishui every year, making sweet potatoes a "golden nugget" for farmers' income through raw material procurement and job creation, effectively contributing to rural revitalization and regional industrial upgrading, and fulfilling its corporate social responsibility through practical actions.
Looking ahead, Shandong Kunda Biotechnology Company Ltd. will continue to uphold the philosophy of "technological innovation, integrity management, quality first, and customer paramount," deeply cultivating the biochemical industry. We will continuously strengthen our advantages in technological innovation and supply chain extension, driving the SHANDONG KUNDA BIOTECHNOLOGY brand towards a higher level and a broader international stage. In the wave of green development and industrial upgrading, KUNDA BIOTECHNOLOGY COMPANY will move forward with more steady steps and superior quality, continuously breaking through technological barriers, expanding industrial boundaries, and writing a new chapter in the high-quality development of the biochemical industry, forging a more globally influential industry benchmark.
