Sibur, Russia’s largest producer of polymers and synthetic rubbers, has announced that construction of its flagship investment project, the Amur Gas Chemical Complex (Amur GCC) in Russia’s Far East, was 92% complete as of the end of 2025.
The Amur GCC is set to become one of the world’s largest polymer production facilities, with a design capacity of 2.3 million tons of polyethylene and 0.4 million tonnes of polypropylene per year. The first commercial batches of polyethylene are expected in the third quarter of 2026, with polypropylene production scheduled to begin in 2027.
Sibur’s new facility is located near the Chinese border and close to Russia’s Pacific ports. This geographic position makes exports from the Amur GCC to Southeast and South Asian markets economically attractive.
The scale of production, use of advanced process technologies, and access to hydrocarbon feedstocks from Eastern Siberia place the facility in the first quartile of the global cost curve, ensuring strong competitiveness and resilience to market volatility.
The Amur GCC will produce polyethylene grades that Sibur has not manufactured previously, including mHDPE, which enhances the elasticity of multilayer films without compromising transparency, and PERT polyethylene for hot-water pipes with elevated strength requirements. The complex will also produce specialty polypropylene grades for injection moulding and BOPP films.
Commissioning activities are currently underway at the complex’s steam cracking unit. During the cracking process, hydrocarbon feedstock – ethane and LPG – is converted into ethylene and propylene at temperatures of around 850°C. In terms of environmental performance, the steam cracking unit will meet best-in-class global standards.
The Amur GCC is Sibur’s largest project since the launch of the ZapSibNeftekhim polymer complex in Western Siberia in 2019. ZapSibNeftekhim has a capacity of 2.5 million tonnes of polyethylene and polypropylene per year, with products exported to dozens of countries worldwide, including China, Turkey, and Vietnam.
