State-of-the-Art CTMP Facility

The factory is designed to offer a broad range of products based on our CTMP pulp, SCA More. Additionally, we have the capability to customize solutions for customers around the globe. Enabled by the availability of and expertise in handling various wood types, including pine, spruce, aspen, contorta, and particularly birch. A versatile yet challenging raw material, setting SCA apart as one of the very few pulp producers in the world capable of effectively processing it. Moreover, the integration of new technology and equipment has further improved environmental performance.

In the production of chemical thermomechanical pulp (CTMP), wood chips are treated with sodium sulfite and steam before being ground into pulp, which is then bleached with hydrogen peroxide. We produce the sodium sulfite ourselves from sulfur dioxide and sodium hydroxide. As part of the pulp production process, district heating is also generated for the local area.

There were several important reasons for expanding CTMP production at the Ortviken industrial site. Significant efforts were required to modernize the old mechanical pulp facility at the Östrand pulp mill, and the move also simplified expansion plans for the sulfate pulp mill. The modern equipment at Ortviken saved both time and money, as the CTMP facility was installed in existing buildings, while a  new chip handling system and a building for dewatering, drying, and baling were established. The total investment amounted to 1.45 billion SEK.
