Dalian Daping Oil Chemical Co., Ltd., formerly known as Zhuanghe Tongda Oil Chemical Factory, was established in 1988. It is a large private enterprise mainly engaged in the production, processing, and research and development of soybean oil chemical products. The company has been in the oil industry for over 20 years and enjoys a high reputation among its peers. With the growth and expansion of the company's market share, in 2007, it invested 100 million RMB to build a modern, garden-style factory in the Dalian Chemical Industry Park, covering an area of 77,000 square meters. The company primarily uses by-products or waste oils from the soybean oil production process as raw materials. Through research and development and the introduction of advanced foreign technologies, along with the use of state-of-the-art production equipment, the company produces high-quality pure oleic acid, stearic acid, and black oil, among other series of products. The annual production capacity for oleic acid is 10,000 tons, with an average annual sales revenue exceeding 100 million RMB. The company's products are indispensable raw materials for the domestic chemical and pharmaceutical industries. After the new factory was built, it operated smoothly, generating significant economic and social benefits. This success is due to the adoption of the most advanced technology and equipment, including a substantial investment in building one of the most advanced biodegradable wastewater treatment plants in China, which passed national inspections at the first attempt, with all wastewater treatment indicators meeting national standards. Additionally, the company is the only enterprise in Dalian designated and qualified to legally collect used cooking oil, ensuring its proper disposal and preventing unscrupulous vendors from using it to harm public health, thus achieving great social benefits. The company adheres to a management philosophy focused on standardized management, governance according to systems, valuing talent, clear rewards and punishments, and enhancing the overall quality of all employees. It is committed to integrity and mutual benefit, brand cultivation, creating value, and giving back to society, thereby increasing its core competitiveness. The company works hand in hand with industry peers to contribute to the revitalization of China's oil chemistry sector.
