Shandong Dongjia Group Co., Ltd. was established in 2002 and has four wholly-owned and holding companies, covering an area of ​​700,000 square meters, with more than 2,200 employees, including nearly 600 scientific and technological personnel. The group produces 160,000 tons of titanium oxide, 900,000 tons of sulfuric acid, and 60,000 tons of ammonium sulfate annually, and has developed into one of the largest titanium oxide production bases in Asia.

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 developing enterprises through science and technology and innovative development. The average investment in scientific and technological research and development each year exceeds 3.7% of sales revenue, and there are nearly 600 professional and technical personnel, including more than 50 senior technical personnel. Based on the existing postdoctoral research workstations, academician workstations, provincial enterprise technology centers and Taishan scholar positions, a titanium oxide technology research and development center is established. Cooperate with the Institute of Process Engineering of the Chinese Academy of Sciences to complete the "Titanium Dioxide Clean Production Technology and Demonstration" project; passed the "Ammonium Sulfur Titanium Co-production Titanium Dioxide organized by the State Commission of Industry and Information Technology, the Chinese Academy of Environmental Sciences, and the China Petroleum and Chemical Industry Federation. Clean production process "Scientific and technological achievements identification, this process will be promoted nationwide as the clean production standard for the domestic titanium dioxide industry. The continuous improvement of corporate innovation capabilities has effectively stabilized product quality while greatly improving corporate brand awareness and market share, and has also enabled companies to gradually gain the industry's voice in the fierce market competition.

The Group insists on scientific development and strictly extends the industrial chain in accordance with the model of "resource-product-renewable resources", and gradually forms the "titanium oxide as the leader, with sulfuric acid, steam reuse, by-product ammonium sulfide, waste heat power generation, and comprehensive utilization" Circular industrial chain. The "12th Five-Year Plan for Comprehensive Utilization of Vanadium Titanium Resources and Industrial Development" issued by the National Development and Reform Commission is an important guide for efficient allocation of vanadium titanium resources, adjustment of industrial layout, and technological upgrading and transformation of my country's vanadium titanium resources. It clearly states that Dongjia Group is included in vanadium titanium Resource industry base is the first in the titanium dioxide industry, and it is also a high recognition of Dongjia's achievements in the comprehensive utilization of titanium resources in recent years.
