Recently, the media tour for the 2025 "China Longevity Town · Quangang" Half Marathon kicked off on March 22. The first stop of the interview group was the Quangang Petrochemical Park, where they explored the new materials project of Fujian Baihong Chemical Co., Ltd. At the construction site, a massive liquefied gas low-temperature tank was already completed, and workers were installing pipes on the top of the tank.

The liquefied gas low-temperature tank is installing pipes.

As a key provincial project, this new materials project is divided into three phases, with a total investment of approximately 13.8 billion yuan. The market applications of the products cover three emerging industries: biodegradable materials, the photovoltaic industry, and automotive power batteries. The first phase involves an investment of about 5.8 billion yuan and is currently under construction, with the main projects being the annual production of 150,000 tons of maleic anhydride and 430,000 tons of carbonate series products.

The ongoing project is the green and intelligent technological transformation of Fujian Baihong Chemical New Materials, which includes production facilities for 474,000 tons/year of carbonate series products and 150,000 tons/year of anhydride products. This project will establish an internationally advanced digital workshop for new materials, meeting the requirements for automated production and the intelligent digital needs of downstream customers in areas such as testing and logistics. "Currently, the laboratory building and the central control building of the project are basically completed, and the main production facilities have been installed and are undergoing pipeline welding and other work," said Vice General Manager Lv Tao. The anhydride facility is expected to start trial production in May, while the carbonate combined facility is expected to begin trial production in July.
