As a core production unit of Shandong Haihua Group, Shandong Haihua Co., Ltd.'s soda ash plant, with an annual soda ash production capacity of 2.8 million tons, ranks first among domestic synthetic alkali producers, accounting for approximately one-tenth of the national total capacity. It is a leading single-plant synthetic alkali manufacturing base globally.
The plant, formerly known as Shandong Weifang Soda Ash Plant, was established in 1983 as a key national "Seventh Five-Year Plan" project and commenced operation in 1989. After years of technological upgrades and capacity optimization, it now has two production lines, one new and one old, employing the industry-mature ammonia-soda process to stably produce light soda ash, heavy soda ash, and food-grade soda ash. Its products are widely used in key sectors of the national economy, including building materials, chemicals, metallurgy, printing and dyeing, and food processing.
Leveraging its coastal location and abundant brine resources, Shandong Haihua Soda Ash Plant has continuously promoted intelligent transformation and green, low-carbon upgrades. It has been successively awarded the titles of National Green Factory, Energy Efficiency "Leader" in Key Energy-Consuming Industries, and "Good Products Shandong" Brand Enterprise. Many of its process technologies and energy-saving indicators are at the advanced level in the industry.
Currently, the company is accelerating the upgrading and energy-saving environmental protection transformation project of its soda ash plant, with a total investment of 4.837 billion yuan. Through process iteration and equipment upgrades, it will further improve energy efficiency, reduce overall energy consumption, consolidate its scale advantage and technological leadership in the domestic synthetic alkali field, and provide solid support for the high-quality development of my country's soda ash industry.
