Shandong Dongjia Group Co., Ltd., one of the top ten brands of titanium dioxide, a large-scale titanium oxide production base in Asia, is a comprehensive enterprise integrating titanium oxide development/supporting sulfuric acid/steam reuse/by-product ammonium sulfate/waste heat power generation/comprehensive utilization of the circular industrial chain

Shandong Dongjia Group was established in 2002, with 4 wholly-owned and holding companies, covering an area of 700,000 square meters and employing more than 2,200 people, including nearly 600 scientific and technological personnel. With an annual output of 160,000 tons of titanium oxide, 900,000 tons of sulfuric acid and 60,000 tons of ammonium sulfate, the group has developed into one of the largest titanium oxide production bases in Asia.

Scientific and technological innovation is an inexhaustible driving force for the long-term development of enterprises. Over the years, we have always adhered to the concept of rejuvenating enterprises with science and technology, innovation and development, and the average annual investment in scientific and technological research and development exceeds 3.7% of sales revenue, with nearly 600 professional and technical personnel, including more than 50 senior technical personnel. On the basis of the existing postdoctoral research workstation, academician workstation, provincial enterprise technology center and Taishan scholar position, the leading technology research and development center of the domestic titanium oxide industry has been established. Cooperate with the Institute of Process Engineering, Chinese Academy of Sciences to complete the "Titanium Dioxide Cleaner Production Technology and Demonstration" project; It has passed the scientific and technological achievement appraisal of the "ammonium sulfate titanium dioxide clean production process" organized by the State Commission of Industry and Information Technology, the Chinese Academy of Environmental Sciences and the China Petroleum and Chemical Industry Federation, and the process will be promoted nationwide as a clean production standard for the domestic titanium dioxide industry. The continuous improvement of the company's innovation ability has greatly improved the company's brand awareness and market share while effectively stabilizing product quality, and has also enabled the company to gradually grasp the right to speak in the industry in the fierce market competition.

The group adheres to scientific development, extends the industrial chain in strict accordance with the model of "resources-products-renewable resources", and gradually forms a circular industrial chain of "titanium oxide as the leader, supporting sulfuric acid, steam reuse, by-product ammonium sulfate, waste heat power generation, and comprehensive utilization". The "Twelfth Five-Year Plan for Comprehensive Utilization and Industrial Development of Vanadium and Titanium Resources" issued by the National Development and Reform Commission is an important guide for the efficient allocation of vanadium and titanium resources, industrial layout adjustment, and technological upgrading. The group has successively won the titles of "National Advanced Unit of Comprehensive Utilization", "Advanced Collective for the Development of Circular Economy" and "Excellent Enterprise with the Most Sense of Social Responsibility in Zibo City". Dongjia is a national advanced unit of chemical environmental protection, won the title of "low-carbon Shandong" advanced enterprise, was awarded the advanced unit of energy conservation in Shandong Province by the provincial government, and was awarded the company "key supporting technology unit for environmental protection and cleaner production in the petroleum and chemical industry" by the China Petroleum and Chemical Industry Federation.
