Weichang Manchu and Mongol Autonomous County Binfa Potato Starch Co., Ltd. was established on April 15, 2005, located in Shanwanzi Township, Weichang County, with a registered capital of 10 million yuan, covering an area of 32,120 square meters and a building area of 12,240 square meters, with total assets reaching 86.8 million yuan. It currently has an office building of 1,700 square meters, a production workshop of 1,200 square meters, a sewage treatment workshop of 5,800 square meters, a warehouse of 3,000 square meters, and a fresh-keeping storeroom of 540 square meters. It has introduced a set of equipment produced by Inner Mongolia Bosda Machinery Co., Ltd., with a daily production of 150 tons of refined starch, an annual designed production capacity of 10,000 tons, and an output value of 60 million yuan. The company currently has 52 employees, including 8 professional and technical personnel, 12 management personnel, and 32 workers.

Weichang Manchu and Mongol Autonomous County Binfa Potato Starch Co., Ltd. adopts the "base + farmers + company" integrated water and fertilizer management model, forming large-scale, specialized, and industrialized operations for green food, fully relying on the advantages of the county's potato production base. Adhering to the business philosophy of "expanding the market 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 forms such as unified seed purchasing, unified agricultural technical measures, and unified product purchasing, signing purchase contracts with a large number of farmers and establishing close production-sales relationships. The company has self-built a potato base of 8,000 mu, driving 3,312 farmer households, including 500 impoverished households with 1,516 people. Product raw materials cover more than 40 villages in 6 surrounding townships, increasing annual per capita income for farmers by nearly 10,000 yuan.

The enterprise adheres to a green circular development model, deeply cultivating the potato intensive processing industry. To solve the environmental disposal problems of potato residues and wastewater from starch processing, the company will invest 32.8 million yuan to construct a high-protein potato residue product industrialization project. After the production line goes into operation, by evaporating and concentrating the juice water and adding it to the potato residue to enhance the protein index of the residue, high-protein feed raw materials will be produced, which can be used for poultry, livestock, and ruminant breeding, 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.
