Innventia AB is a Swedish research institute formed as a limited company engaged in research, development and missions in the pulp and paper industry, packaging industry and the graphics industry. The activities range from basic research to direct consulting and development assignments in the three industrial areas of the final products bio-based energy, chemicals and materials, graphic media, packaging and logistics. Before April 2009 the institute was named STFI-Packforsk AB. The President is Birgitta Sundblad, who took over the post from Gunnar Svedberg, upon his retirement in June 2011. Wikipedia.

BANUS project aims to develop new multilayer structures for food packaging applications, in order to evaluate their properties as functional barriers, using conventional polymers to achieve new functionalities and open new potential markets for the traditional recycling companies in Europe. Taking into account that the main objective of the project is to guarantee the suitability of the developed functional barrier layers, it is necessary to check that, independently of the quality of the used recycled material, the functional barrier is able to avoid any migration of contaminants to food. A great advantage of BANUS approach is to be able to guarantee food safety when using recycled materials (plastic and paper) even coming from non-authorized recycling processes in food packaging structures. The project will consider the substitution of a percentage of virgin material by recycled material (paper or plastic) in the selected structures in order to develop more environmental friendly food packaging structures. As the main requirement of food packages is always to guarantee food safety for consumers, this substitution will be achieved after evaluating the functional barriers positioned between recycled layers and foodstuffs.

• Background: It is with increasing interest that wood materials are now being considered as a green resource. For improving the product performance of wood derived materials new ways of separating them from wood are required. Thus, there is a great demand for a better understanding of the ultrastructure of wood and how the components are interaction on a molecular level in building up its properties. • Material and method: By the use of microscopic and spectroscopic techniques combined with mechanical forces, new knowledge regarding especially the role of the matrix polymers, the hemicelluloses and lignin, has been gained. This relates specifically to molecular interaction and orientation. • Results: It is here demonstrated that all of the wood polymers within the secondary cell wall exhibit a preferred orientation along the fibrils. The degree of orientation decreases in the order cellulose, hemicelluloses to the lignin which only shows a small degree of orientation, probably induced by structural constrains. • Conclusion: This orientation distribution is probably what has to be considered to better predict transverse cell wall properties. Moisture accessible regions are also aligned in a parallel arrangement in the cellulose fibrils explaining its high moisture resistance. The lignin is surprisingly inactive in the stress transfer in the secondary wall. This could perhaps be related to the function of lignin providing compressive, hydrostatic resistance in the lenticular spaces between fibrils, when longitudinally straining the fibre. This knowledge of the ultrastructural properties of the wood polymers, here presented, provides for a better understanding of the cell wall properties. © 2014, INRA and Springer-Verlag France.

Papermaking is to a large extent a multiphase flow process in which the structure of the material and many of the relevant properties of the final product are determined by the interaction between water and the wood fibers. The dominant feature of a suspension composed of wood fibers and water is its inherent propensity to form bundles of mechanically entangled fibers, known as fiber flocs. However, the phenomena apparent throughout the papermaking process are not unique but in fact have a generic fluid dynamical nature. © 2011 by Annual Reviews. All rights reserved.

A process for lignin removal from alkaline pulping liquors (black liquors) has been developed within the FRAM2 R&D Program (Future Resource Adapted Pulp Mill, part 2). The lignin product (Fig. 1) from a demonstration plant, owned and operated by Innventia (formerly STFI-Packforsk), was characterized and used in different combustion trials with good results - co-firing of lignin and bark in a fluidized bed boiler, co-firing with coal in a PFBC (Pressurized Fluidized Bed Combustion) boiler and firing of lignin in a fullscale lime kiln. The process development and operation of the demonstration plant has displayed good results. Runnabilily in the demonstration plant and the lignin quality have been both very good. The work done on the investment and operational costs showed great potential for improving the concept of economy, which is very promising.

The overall objectives are to demonstrate a new biobased, renewable and economically viable carbon fibre (CF) precursor lignin produced in Europe with European raw material and to develop conditions for its processing into CF and structural CF composites. The target is a cost-effective biobased CF for use in reinforced composites delivering sufficient enough strength properties for large-volume automotive applications. Reducing vehicle weight is a decisive factor for successful fulfilment of the future targets in EU regulations regarding CO2 emissions from the automotive sector. CF reinforced plastics has been introduced as a low-weight material replacing/complementing steel and aluminium. Todays CF production is based on use of a petroleum-based raw material, PAN, which is costly due to the starting precursor and the process for turning it into CF. Most PAN used in Europe is imported. The automotive sector has identified a need for a cheaper lower-grade CF to meet the demands of components in normal consumer cars. Lignin from kraft pulp mills is a green, sustainable, abundant and cost-efficient new potential CF precursor. The European pulp and paper industry has a need for additional revenues due to the global competition and the decline in printing and writing paper. Successful lignin applications like CF will create new business opportunities and new jobs also in rural areas where the pulp mills are located. The development of lignin-based CF is still in laboratory scale and material properties meeting high-quality product demands is the main challenge. Now a new technology in commercial operation makes it possible to produce lignin with new properties, higher purity and with less impact on the pulp mill operation. The idea is to tailor kraft lignin properties already in the lignin separation/upgrading and optimise the lignin for target automotive applications. The consortium has unique competence through the complete value chain to realise this new concept.
