The RISE institutes Innventia, SP and Swedish ICT have merged in order to become a stronger research and innovation partner for businesses and society.
During 2017 will be one of several websites within RISE. Please visit for more information about RISE.

Cluster Research Programme 2012-2014

The current Cluster Programme started in January 2012. This programme addresses issues of great interest to our customers, like energy and raw material savings, production efficiency and new bio-based products.

The kraft pulp fibre line


The kraft pulping processes need constant refinement to stay competitive: improvement of the fibre properties and production efficiency of the kraft pulp mill both yield increased utilisation of the natural resources used in the given process. Thus, research performed within the area of chemical pulping should be driven by these areas.

Chemical and energy recovery in the kraft pulp mill


The basic idea is to gather, describe and propose solutions to well-known process disturbances induced by NPE in the recovery area and fibre line of the kraft pulp mill.

Biorefinery processes and products


Rising wood and energy costs makes it increasingly urgent for the forest-based industry to find by-product uses with higher market value than the fuel value. This is also reflected in the quickly growing involvement by forest industry companies in biorefinery activities the last few years.

Fibre, stock and product optimisation


Traditionally the stock treatment processes focus on the use of the entire pulp, or choosing a different fibre raw material. Instead, the focus should be shifted towards using and/or optimizing the components of a given stock e.g. fines, long fibers, short fibres, earlywood and/or latewood fibres. These components have largely varying properties and roles in the pulp, and certain product properties could be selectively controlled without influencing the remaining properties if this aspect is taken into consideration.

Nanocellulose process


Due to the high potential of nanocellulose in e.g. paper applications, there is a desire to make the nanocellulose process economically viable. Innventia’s laboratory scale processes have been shown to be very energy efficient and the processes have been upscaled in Innventia’s new nanocellulose pilot factory. However, there are several remaining challenges to be addressed like optimisation of the pre-treatment processes.

Optimized production by advanced paper chemistry


In order to increase the profit, paper and board producers strive to lower their raw material costs. Independent of quality, papermakers have to compromise between retention, formation, strength and dewatering. A fine paper producer might want to increase the filler content to decrease the use of the more expensive fibres or the board producer might want to use bulking fibres. In order to do so the retention has to be improved, which requires increased use of retention aids, which deteriorates the formation. The poor formation can be improved by formation aids, but these often deteriorate dewatering and the strength of the paper. The strength is also deteriorated by the increased filler content.

Process efficiency and variability in papermaking


In order to remain competitive with respect to energy and material consumption, the paper and board manufacturers need to continuously improve the efficiency of the production process and reduce the heterogeneity of the product.

Paper mechanics for improved quality


The cluster has the following aims: Provide relevant, robust, and reliable test methods. Identify mechanisms behind different types of paper behaviours. Clarify how furnish, papermaking strategy and chemical additives relate to paper properties. Define strategies to control and design paper properties.

Improved convertability of paperboard


The aim is to increase productivity, reduce customer complaints, and reduce waste caused by damaged packages by e.g. providing experimental methods for study of creasing and folding, developing generally applicable methods to assess convertability.
Contact: Johan Alfthan

New wood fibre-based materials


Our aim is to develop new wood fibre-based materials and show their potential in concept demonstrators.
Contact: Fredrik Berthold

Bio-based barriers for packaging materials


The aim is to improve fibre-based packaging materials with bio-based barrier materials. By finding concept applications, defining process and product requirements, a base from which new barrier materials can be developed has been found. Concept demonstrators will be developed based on partners’ requirements.

Tools to predict flexographic print quality for packaging


This cluster will work with hypotheses based on our sound expertise and determine the areas to investigate using the state-of-the-art measurement techniques. The focus is on the use and development of tools that can be used when improving flexographic printability, in terms of high, consistent and predictable print quality.

Tissue, 2013 – 2014


It is important for the pulp, paper and tissue industry to make efficient use of the required resources and to develop efficient production processes to remain competitive. Reducing the grammage with maintained product functionality by changing or modifying the pulp are ways of improving the cost efficiency. Important product properties for most of the tissue products are strength, softness, and absorbency. When investigating a change or modification of the fibres at lower basis weights, the effect on crucial product properties cannot be sacrificed. For the tissue industry this will require increased knowledge and better understanding on how the product properties change at lower basis weights.
