China's first full-chain green and low-carbon ethylene project was put into operation on Thursday, lifting annual ethylene capacity at the Dushanzi Petrochemical complex to more than 3 million metric tons and making it the only ethylene production base of that scale in the country's central and western regions.

Dushanzi Petrochemical is a subsidiary of State-owned China National Petroleum Corp, or CNPC.

The expansion, which will boost capacity by 1.2 million tons per year, comes as China seeks to strengthen domestic production of higher-value petrochemical materials and develop manufacturing further inland using the region's abundant oil and gas resources.

Located in Shangku Petrochemical Industrial Park in Korla, Northwest China's Xinjiang Uygur autonomous region, the project integrates renewable electricity, carbon capture and petrochemical production technologies to lower emissions while producing key industrial feedstocks, according to CNPC.
