MoRe Research

MoRe Research AB is being integrated into RISE. The rebranding from MoRe Research to RISE will take place in stages from 1 December 2024. The change not only means a new name, but also an increased focus on offering first-class se…

Papermaking Network in 60 minutes

On 25 May, RISE invites you to an hour-long live event where we introduce the Papermaking Network. With our new initiative, we want to gather representatives from all Scandinavian mills for pulp, graphic paper, specialty, packagin…

Analysis of wood chips for pulp & paper production

The quality of the wood chips is critical to the production of pulp, and at RISE we offer several different analyses to ensure the quality of the wood chips. By carefully examining and evaluating various properties, we can identif…

Bleaching of Cellulose

By understanding the bleaching process and making the necessary adjustments and optimisations, the pulp and paper industry can produce high-quality products with the desired properties and durability. This not only helps to fulfil…

Efficient Evaluation of Antifoam Solutions in the Process Industry

By utilizing the customer's filtrate or other process fluids, we can efficiently evaluate various antifoam solutions without the need for extensive and costly full-scale trials.

Mechanical pulping

Are you looking for energy efficient pulp production or improved bulk in your board grade? RISE could be your helping hand.

Gas measurements - DNCG

What is normally called dilute non-condensable gases, DNCG contains a mixture of different sulfur-containing substances; hydrogen sulfide, methyl mercaptan, DMS and DMDS.

Analyses - process chemicals & materials

In the cellulose industry, it is crucial that process chemicals are carefully analysed, controlled and classified in order to be able to take appropriate measures in case of post-processing of materials.

Studies of Wood and Wood Handling

Studying wood can provide insights that are crucial to answering several important questions in the pulp and paper industry, one of which is whether it is possible to introduce new wood species into production while maintaining th…
