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 Paper Production and Pulp

The quality of the wood chips is crucial for pulp manufacturing, and at RISE, we offer several different analyses to ensure the quality of the wood chips. By carefully examining and assessing various properties, we can identify an…

Wood - Evaluation of Results on Performance Test

In conjunction with investments and renovations in paper and pulp production lines, it is common to conduct warranty runs. This may involve anything from replacing a sieve or part of the equipment to, for example, entire pulping o…

Wood Handling Studies Improve Production Economics

The cost of wood is the largest expense for pulp mills, hence the need to minimize wood losses during debarking is significant. However, debarking cannot occur too quickly, as it increases the bark content in the wood chips delive…

Real-time Chip Impregnation Pilot

Impregnation studies are of interest for all chemical pulp processes, whether the end product is paper pulp or dissolving pulp. It is especially important to have properly impregnated chips for pulp mills seeking to increase produ…

Studies of Wood Properties - Important for Process and Final Product

By studying wood, one can obtain insights crucial for answering several important questions within the pulp and paper industry. One of these questions is whether it is possible to introduce new wood species into production while m…

Bleaching of Cellulose

By understanding the bleaching process and implementing necessary adjustments and optimizations, the paper and pulp industry can produce high-quality products with desired characteristics and durability. This not only helps meet c…

Cooking of Cellulose and Residues on a Pilot Scale

The pilot digester is a central component of the process within the pulp and paper industry, and its flexibility is crucial for meeting various requirements and needs that may arise in production conditions. At RISE, we have dedic…

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.

Quality Assessment of Pulp for the Production of Fluff Pulp

With an increased population, sanitary products are used to a greater extent. At RISE, producers for fluff pulp can optimize and develop the process and product, both for the sake of the environment and the user, and performing a …

Demand for Effective Sulfur Purification Solutions

The increasing demand for efficient solutions for the collection and disposal of Dilute Non-Condensable Gases, (DNGC) has become more pronounced, especially with the EU's tightened regulations requiring industries to use the …

Expertise in Dissolving Pulp for Textile

Dissolving pulp is an important product used in the manufacture of fiber materials, which are used in the textile industry.

Mechanical pulping

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

Fluff pulp

With an increased population, sanitary products are used to a greater extent. Producers for fluff pulp can at RISE optimize and develop the process and product, both for the environment and the user, and performing a quality asses…

Lignocellulose - Pulp Technology

Pulp production plays a central role in the bioeconomy, the transition towards a fossil-free society, and circular processes. The main part of the fiber line is the pulp mill, where wood is treated with chemicals to produce pulp w…

Separation of Lignocellulose and Residue

The earth's circular and renewable raw materials are in demand and should be sufficient for a lot and increasing the need for research and development of them so that each element is put to good use. Separation of cellulose from f…

Steel Belt Press - Stronger Materials

By applying high pressure and heat, the fibers in the pulp can be compressed and bonded together in a way that increases the paper's density and strength. The lignin in the mechanical pulp plays a crucial role in creating str…

Development of tissue products in small-

The experimental paper machine, XPM, can produce paper in grammages between 15 and 300 gsm. As it is equipped with a Yankee cylinder it can also very easily be used for pilot scale production of tissue.

XPM - Paper pilot for research

The Experimental Small Paper Machine (XPM) constitutes an important paper pilot and is a cost-effective tool for conducting tests and evaluating new applications for pulp and chemicals. Its cost-effectiveness and ability to genera…
