Hainan Sikeyuan Green Energy Technology Co., Ltd. was established on September 9, 2024, and is located in the Yangpu Economic Development Zone of Danzhou City, Hainan Province. Hainan Sikeyuan’s 300,000 tons per year bioenergy project is a key green and low-carbon initiative in Hainan Province, with a total investment of around 1.2 billion yuan; it is located in the Yangpu Petrochemical Industrial Zone. The project uses waste animal and plant fats such as acidified oil and gutter oil as raw materials to build a 300,000 tons per year bio-jet fuel hydrogenation facility and a 2,000 Nm³/h light hydrocarbons hydrogen production facility, in order to produce green energy products such as biodiesel, bio-jet fuel, and bio-naphtha.
Construction of the project began in September 2025, with continuous work carried out during the Spring Festival in 2026; 350 workers were involved in the on-site operations. At present, efforts are being accelerated to complete the steel structure construction, equipment installation, and decorative work. Completion is scheduled for June 2026. Once completed, it is expected to reduce carbon dioxide emissions by over 400,000 tons per year, which is of great significance for optimizing the regional energy structure and supporting the green and low-carbon development of Hainan Free Trade Port.
As of January 2026, significant progress has been made in the construction of the 300,000-ton/year bioenergy project at Sikeyuan in Hainan, which is being carried out through EPC contracting by China Fifth Ring Engineering Co., Ltd., a subsidiary of China National Chemical Engineering Corporation. The first three core refining reactors were successfully installed within 3 days, marking the official start of the equipment installation phase for the project.
