ANDRITZ to supply upgrade to the world’s largest BCTMP system for P&W grades at Shandong Huatai Paper, China

International technology Group ANDRITZ has received an order from Shandong Huatai Paper Industry Shareholding to upgrade an existing BCTMP (bleached chemi-thermo-mechanical pulp) plant to become the world’s largest mechanical pulping line for P&W (Printing & Writing) paper production at the mill in Dongying, Shandong province, China.

Start-up is scheduled for the fourth quarter of 2022.

The existing BCTMP line will be upgraded and rebuilt to become a state-of-the-art P-RC APMP- (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) system. The fiberline’s production capacity for mechanical pulp to make P&W paper grades will thus be increased from 100,000 to at least 300,000 admt/a, making it the largest in the world.

ANDRITZ will rebuild two existing high-consistency (HC) refiners as well as the existing screw presses, disc filters and screens, and supply new equipment for all other process steps. The upgrade project features the following technological highlights:
*New MSD Impressafiner with the latest IIoT features for optimum wood chip maceration and chemical impregnation
*New Side-Entry Plug Feeder (SEPF) feeding system for constant and efficient HC refiner feeding
*Rebuild of the existing HC refiners, including the Hydraulic Commander, to enable fully autonomous monitoring and control
*New DCS system as a future-oriented control system for the new fiberline

The upgraded mechanical pulping line will process a mixture of eucalyptus, poplar and acacia wood chips. The scope of supply also includes the basic engineering as well as the supervision of mechanical installation, commissioning and start-up.

Wang Hairong, Project Director of Shandong Huatai Paper Industry Shareholding says: “ANDRITZ offered a very convincing overall concept to boost our fiber quality and production capacity. With the new line we will also gain high flexibility in production – this exactly meets our needs.“

Shandong Huatai Paper Industry Shareholding is part of the Huatai Group, a company listed on the Shanghai Stock Exchange and an important global player in the paper and chemicals production sectors. The group is the world’s largest producer of newsprint and the largest producer in the chlorine-alkali industry in China. Besides this, the group makes all sorts of P&W paper, tissue and specialty paper grades. The Huatai Group produces three million tons of paper and board as well as two million tons of chemicals per year.

GreenFirst Announces Plan to Spin-Out Kap Corporation

GreenFirst Forest Products Inc. announces that it intends to complete a spin-out transaction of Kap Corporation, whereby the shares of Kap will be held directly by the shareholders of the Company. The Spin-out is expected to be completed in Q4 2024. GreenFirst will hold a shareholder meeting on September 12, 2024, where shareholders will be able to vote on the Spin-out. The record date for shareholders entitled to vote at the Meeting will be August 8, 2024. The Spin-out of Kap is part of the natural progression of the decentralization and deconsolidation of the newsprint mill that was originally disclosed by GreenFirst in the Fall of 2023. The Spin-out will enable GreenFirst to focus on its core business of being a pure-play lumber producer, offering shareholders a stake in any future upside from the development of Kap. Under the new structure, Kap will be able to explore numerous possibilities that were not feasible under the original GreenFirst ownership structure. As a separate company, Kap will consider independent financing alternatives and partnerships in the future. Kap Paper Inc. is the only chip consuming facility in Northeastern Ontario and the Spin-out provides Kap Paper with the potential to pursue new opportunities to support the green economy as part of a broader Northern Ontario forest strategy.

Rails Instead of Roads – Koehler Invests 1 Million Euros

As part of sustainable logistics concepts and in order to increase supply chain reliability for an important raw material, pulp, Koehler is making greater use of rail transportation. “We have expanded the existing rail connection, which was too small, added manual underground switches to it, and also purchased a modern shunting robot. This will enable employees to handle shunting work at the plant independently and flexibly and to process four times as much incoming tonnage,” explained Andreas Riedlinger, logistics team leader at Koehler. Total investments amounted to EUR 1 million. Since the start of the year, three to four weekly block trains have re-placed deliveries by truck, which amounted to as many as 15 per day.
