Weichang Manchu and Mongol Autonomous County Binfa Potato Starch Co., Ltd. adopts the "base + farmers + company" integrated water and fertilizer operation model to achieve large-scale, specialized, and industrialized operation of green food, fully relying on the advantages of the county's potato production base. Adhering to the business philosophy of "expanding markets with price, winning trust with quality, driving capacity with technology, and gaining reputation with service." Weichang Manchu and Mongol Autonomous County Binfa Potato Starch Co., Ltd. adopts measures such as unified seed purchasing, unified agricultural techniques, and unified product acquisition, signing purchase contracts with numerous farmers to establish close production-sales relationships. The company has built a potato base of 8,000 mu, driving 3,312 households, including 500 impoverished households with 1,516 people. Raw materials cover over 40 villages in 6 surrounding townships, increasing the annual per capita income of farmers by nearly 10,000 yuan. The enterprise insists on a green circular development model and deepens the intensive processing of potatoes. To solve the environmental disposal of potato residue and wastewater from starch processing, the company will invest 32.8 million yuan to build an industrialization project for high-protein potato residue products. After the production line is put into operation, the protein index of potato residue will be elevated by adding evaporated and concentrated juice water to the residue, producing high-protein feed raw materials for livestock, poultry, and ruminants, turning waste into treasure. This constructs a "starch production - by-product deep processing" closed-loop industrial system, providing technical support for the high-value utilization of potato processing waste.
