Valmet will supply what it says is the world’s largest bleached chemi-thermomechanical pulp (BCTMP) line to Guangxi Sun Paper Co., Ltd.’s new Beihai mill in China.

The start-up is scheduled for the fourth quarter of 2021. The order was included in Valmet’s orders received of the second quarter 2020. The value of the order will not be disclosed.

Valmet’s delivery is part of Sun Paper’s new greenfield mill in Beihai, which will eventually have a total pulp and paper capacity of 3.5 million tonnes annually.


This order complements the fine paper machine, automation and recovery boiler order, which Valmet announced in April 2020 and the cooking and fiberline order announced at the beginning of June.

The Valmet-delivered BCTMP line is integrated to a folding boxboard line, which will have capacity of 1,800 air-dried metric tonnes per day.

Valmet’s delivery includes the main equipment for the BCTMP line including refiner and wash press technology. The EPS delivery scope covers engineering, procurement and site supervision. Training, site services and corresponding spare parts are also a part of the scope.
