Doublestar starts up scrap tire pyrolysis plant

Zhumadian, China - Doublestar has started up phase one of a scrap tire pyrolysis plant in Zhumadian, Henan province that is able to handle 100,000 tonne rubber or 10 million passenger car tires each year.

“The plant has been running smoothly for over a month,” said Doublestar Group chairman and general manager Chai Yongsen during his speech at the China Rubber Conference held in Guangzhou.

Located in Zhumadian’s Runan county, the new plant’s phase one has 133,000 m2 land area and received €44 million (330 million yuan) investment.

The 100kt of scrap tires at Doublestar’s new plant would produce 45kt pyrolysis oil, 35kt carbon black, 12kt steel cord and 8kt pyrolysis gas each year, generating €48 million annual revenue.

This is the world’s first plant of its kind with “zero pollution, zero emission, zero residue,” said Chai.

Doublestar also plans to build two more scrap tire pyrolysis plants in Shiyan, Hubei and Qingdao, Shandong.
